Kyle J.Norton Skin aging is one of most visible ageing process which occurs constantly in our skin organ. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals, to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin, affect skin elasticity and tightness(a). Other suggested that free radicals induced domino effects in production of reactive oxygen species, can react with DNA, proteins, and fatty acids, causing oxidative damage and impairment of antioxidant system, leading injuries damage regulation pathways of skin, including wrinkles, roughness, appearance of fine lines, lack of elasticity, and de- or hyperpigmentation marks(b).
Vitamin D is a fat-soluble secosteroids found in small amount in few foods, including salmon, mackerel, sardines and tuna. The vitamin plays an important role in modulation of cellular proliferation, apoptosis induction, tumor growth suppression and promotion in absorption of minerals, including calcium, iron, magnesium, phosphate and zinc.
1. Plasma of vitamin D
Levels of 25-hydroxyvitamin D levels [25(OH)D] levels was associated to risk of skin aging as the study at Universitätsklinikum des Saarlandes, showed that UV-radiation exerts both skin aging -promoting and -inhibiting effects on skin aging. Altered mineral homeostasis caused by a high vitamin D activity, exhibited the premature aging that include, besides short lifespan, retarded growth, ectopic calcification, immunological deficiency, osteoporosis, atherosclerosis, hypogonadism, skin and general organ atrophy but laboratory investigations convincingly shoed that vitamin D compounds protect the skin against the hazardous effects of various skin aging-inducing agents, including ultraviolet (UV) radiation(1). Therefore optimal serum concentration are necessary due to its U-shaped risk(2). The Stanford University School of Medicine study indicated that vitamin D deficiency enhanced low scores for specific photodamage parameters including erythema/telangiectasias, hyperpigmentation, and wrinkling(3), specially in the skin from the 77- and 82-yr-old subjects revealed that aging can decrease by greater than twofold the capacity of the skin to produce previtamin D3(4).
The effects
According to Treviglio-Caravaggio Hospital, daily supplementation of vitamin D indicated is about 800-1,000 IU/day but may increase up to a maximum dose of 2,000 IU/day in conditions of severe vitamin D deficiency with a concomitant reduced or no sun exposure, reduced dietary intake and reduced calcium absorption(5)(6). Some researchers suggested that intrinsic skin aging may reflects the reduction processes that are common in internal organs, as the reduced production of sex hormones influence skin morphology and functions, skin permeability, wound healing, sebaceous lipogenesis, and the metabolism of skin cells in both sex and Vitamin D administered and antioxidant treatment may be beneficial(7). In postmenopausal health, low levels of vitamin D may induce obesity, malabsorption syndromes, medication use (e.g. anticonvulsants, antiretrovirals), skin aging. According to Universidad de Zaragoza, Increased level of the vitamin through regular sunlight exposure (without sunscreens) for 15 min, 3-4 times a week, in the middle of the day in summer may be beneficial, but supplementation intake of vitamin D2 (ergocalciferol) or vitamin D3 (cholecalciferol) should be monitored depending on the dose used and the presence of concomitant medical conditions such as renal disease(8). Dr Johnson MA at the University of Georgia, insisted " Diminished synthesis of vitamin D in the skin that occurs with aging and poor dietary intake contribute to the high prevalence of poor vitamin D status in older adults"(9). Dr. Heaney RP. suggested that cutaneous vitamin D3 synthesis declines with age, it would require input of an additional 2600 iu/d (65 microg/d) of oral vitamin D3 to ensure that 97.5% of older women have 25(OH)D values at or above desirable levels"(10).
Taken altogether, optimal serum concentration was found to interact in enhancing the reduced production of sex hormones and reducing photodamage parameters including erythema/telangiectasias, hyperpigmentation, and wrinkling due to aging.

Skin aging in Vitamin C points of view
Skin aging is one of most visible ageing process which occurs constantly in our skin organ. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals, to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin, affect skin elasticity and tightness(a). Other suggested that free radicals induced domino effects in production of reactive oxygen species, can react with DNA, proteins, and fatty acids, causing oxidative damage and impairment of antioxidant system, leading injuries damage regulation pathways of skin, including wrinkles, roughness, appearance of fine lines, lack of elasticity, and de- or hyperpigmentation marks(b).
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin, found in fresh fruits, berries and green vegetables. It is best known for its free radical scavengers activity and regenerating oxidized vitamin E for immune support. In skin aging, the vitamin may improve solar radiation protection and epidermal aging(1) through production of collagen due to its antioxidant activity(2)(3).
Epidemiological studies, linking vitamin C in prevention of skin damage and aging have produced some consistent results(3a)(3b)(3c), but the large sample size and multi canters studies are necessary to validate it effectiveness.
1. Plasma levels of vitamin C
L-ascorbic acid, was known for its effects on skin-whitening and against anti-oxidation causes of skin aging. During the aging process, levels of vitamin C was found slowly deplete, according to Tokyo Metropolitan Institute of Gerontology in the measurement of plasma and urine of C57BL/6 male mice turnover during 3 to 30 months of aging(4). Therefore, restoration of physiological levels of vitamin C inside the cells might improve the lysosomal degradation (protection of cell from the degradative enzymes, through protection of the cytosol) in the outflow pathway cells and prevent the pathogenesis of glaucomadegrade proteins(5).
Unfortunately, some researchers that higher levels of circulating vitamin C may not provide protection against incident radiographic knee OA, and be associated with an increased risk of knee OA(6) and the 1Panorama Research Institute and Regenerative Sciences Institute, insisted "careful attention to individual and family medical history and personal genomic data may prove essential to make wise dietary and supplement choices to be combined with exercise(7).
2. The effects
According to the Minghsin University of Science and Technology, in doses dependent manner, concentration of L-ascorbic acid, induced absorption of the collagen solution in exhibition of smoothing wrinkles and clear up the spots(8). Ascorbic acid (AA) is essential in stimulation for collagen gene expression. In type 1 and type 4 collagen and SVCT2, the vitamin was found to enhance the expression of type 1 and type 4 collagens and SVCT2 mRNA in cultured human skin fibroblasts at 100 μM AA eplaced every 24h for 5 days to prevent depletion(9). The Chiang Mai University study also supported the effects of ascorbic acid in anti-aging process through exhibition pro and active MMP-2 inhibitory(10). Other study suggested the combined vitamins, including vitamin C in a single formulation had a slightly lower degradation rate and more stable formulations as compared to different preparations containing only one of the vitamins(11)(12). Amazingly, in vivo, application of vitamin C showed to significant reduction of oxidative stress in the skin, an improvement of the epidermal-dermal microstructure and a reduction of fine lines and wrinkles in aged skin within a relatively short period of time of product application(13). The Bruce and Associates study also insisted the effectiveness of vitamin C application over 12 week period as the vitamin enhanced the overall intensity of pigmentation, fine lines and wrinkles, tactile roughness, and laxity with 100% of satisfied overall appearance of tested subject skin(14).
Taken altogether, vitamin C was found to be effective in slowdown skin aging regardless to the cause, through its antioxidant status, down regulated the expression of Matrix metalloproteinase (MMPs) and enhanced production of collagens. Daily ingestion of high-dose vitamin C may be considered safe, but in rare incidence, overdoses in a prolonged period of time, may cause intra-renal oxalate crystal deposition, a fatal nephrotoxicity(15)(16).

Skin aging in Vitamin A points of view
Kyle J.Norton(Draft Article)
Skin aging is one of most visible ageing process which occurs constantly in our skin organ. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals, to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin, affect skin elasticity and tightness(a). Other suggested that free radicals induced domino effects in production of reactive oxygen species, can react with DNA, proteins, and fatty acids, causing oxidative damage and impairment of antioxidant system, leading injuries damage regulation pathways of skin, including wrinkles, roughness, appearance of fine lines, lack of elasticity, and de- or hyperpigmentation marks(b).
Vitamin A is a general term of Vitamin A Retinol, retinal, beta-carotene, alpha-carotene, gamma-carotene, and beta-cryptoxanthin best known for its functions for vision health and antioxidant scavenger and essential for growth and differentiation of a number of cells and tissues.
1. Retinols
Activation of both all-trans retinoic acid and 9-cis retinoic acid in nuclear retinoic acid receptors (RARα, RARβ, and RARγ), may associated to skin aging(1). In chronologically aged and photoaged human skin due to alternation of connective tissue collagen, caused by cysteine-rich protein 61(2) (CCN1, a negative regulator of collagen homeostasis). application of all-trans retinoic acid (RA), the major bioactive form of vitamin A in skin, significantly increased type I procollagen and reduced collagenase (matrix metalloproteinases-1, MMP-1)and suppressed recombinant human CCN1(3).
P-Dodecylaminophenol derived from the synthetic retinoid, in the skin of hairless mice study, exhibited the increased cytokeratin 16 expression which is essential in skin healing and maintenance, without causing the desquamation and erythema(4). In a vivo study in assessing major aging signs and performing three-dimensional profilometry and digital imaging during a 9-month double-blind placebo-control involving 48 volunteers, topical application of a ROL-containing product not only improved all major aging signs including wrinkles under the eyes, fine lines and tone evenness, but also promoted keratinocyte proliferation, induced epidermal thickening and alleviated skin aging signs, without any significant adverse reaction(5). Retinyl retinoate 1, another synthetic version of retinols, showed inhibitory activity against c-Jun than retinol and superior effects on collagen synthesis compared to retinol, and may have the potential to be conveniently used as an additive in cosmetics for prevention and improvement of skin aging and medicines for the treatment of skin troubles(6). Some researchers suggested that topical retinol improves fine wrinkles associated with natural aging, through its effects in induction of glycosaminoglycan, increased collagen production are most likely responsible for wrinkle effacement. Retinol-treated aged skin is more likely to withstand skin injury and ulcer formation along with improved appearance(7). Application of a stabilized 0.1% retinol-containing moisturizer showed the improving lines and wrinkles, pigmentation, elasticity, firmness and overall photodamage(8). N-retinoyl-D-glucosamine, a retinoic acid agonist in the study in comparison with retinol acid, showed the same effective of both in complete disappearance of the wrinkles caused by UVB irradiation probably via RAR transactivation activity, but the synthetic agonist showed no adverse effect in causing skin irritation(9).
2. Carotenoids(beta-carotene, alpha-carotene, gamma-carotene and beta-cryptoxanthin) and Retinal Carotenoids, plant pigments, converted to vitamin A after intake, though to play an important role in prevention and treatment of some diseases through it antioxidant effects.
Nutrition rich in carotenoids is best known to prevent cell damage, premature skin aging, and skin cancer(10). It has been reported to possess potent anti-oxidant properties and widely used in the skin care industry either as topically applied agents or oral supplements in an attempt to prolong youthful skin appearance(11)(12). Free radicals cause of premature skin aging and lead to immunosuppression and the formation of skin diseases, administration of carotenoids may interact with free radicals to enhance the protection system against that destructive(13). Other study suggested that Stress factors such as illness, UV and IR radiation of the sun, and smoking and alcohol consumption reduce the concentration of the carotenoids in the skin of that lead to deeper and denser of the furrows and wrinkles(14).
The testing of high doses of sun-emitted UV-radiation induce reactive oxygen species (ROS) as major pro-oxidants thus inducing premature skin aging, showed a positive effect of Carotenoid-tablets combined with placebo-cream in induced less carotenoid accumulation than carotenoid-tablets alone(15) of that suggested that In contrast to topical application, the systemically applied carotenoids are stored in the body fat tissue and slowly released onto the skin surface with sweat and sebum. Retinaldehyde (RAL) showed a significant improvement of wrinkles(forehead wrinkles, nasolabial folds, crow's feet and perioral wrinkles)(16).In fact, deficiency of vitamin A may result of induced premature aging. In skin of streptozotocin (STZ)-induced type 1 diabetic rats, showed over expression of matrix metalloproteinase -2 (MMP-2) and hyaluronidase (HAase) but not on vitamin A treated mice, through promoting the production of collagen in dermis and inducing cell growth and inhibition of epidermal differentiation in skin tissues(17).
Taken altogether, vitamin A and its variants are found to be effective in prevention of skin damage and skin aging caused by over expression of type I procollagen and under expression of collagenase (matrix metalloproteinases-1, MMP-1).
Recommended intakes of vitamin A, according to the Institute of Medicine of the National Academies (formerly National Academy of Sciences) is 600 µg daily as extremely high doses (>9000 mg) can be toxicity as causes of dry, scaly skin, fatigue, nausea, loss of appetite, bone and joint pains, headaches, etc. As always, all articles written by Kyle J.

N-retinoyl-D-glucosamine, a retinoic acid agonist in the study in comparison with retinol acid, showed the same effective of both in complete disappearance of the wrinkles caused by UVB irradiation probably via RAR transactivation activity, but the synthetic agonist showed no adverse effect in causing skin irritation(9).
2. Carotenoids(beta-carotene, alpha-carotene, gamma-carotene and beta-cryptoxanthin) and Retinal Carotenoids, plant pigments, converted to vitamin A after intake, though to play an important role in prevention and treatment of some diseases through it antioxidant effects.
Nutrition rich in carotenoids is best known to prevent cell damage, premature skin aging, and skin cancer(10). It has been reported to possess potent anti-oxidant properties and widely used in the skin care industry either as topically applied agents or oral supplements in an attempt to prolong youthful skin appearance(11)(12). Free radicals cause of premature skin aging and lead to immunosuppression and the formation of skin diseases, administration of carotenoids may interact with free radicals to enhance the protection system against that destructive(13). Other study suggested that Stress factors such as illness, UV and IR radiation of the sun, and smoking and alcohol consumption reduce the concentration of the carotenoids in the skin of that lead to deeper and denser of the furrows and wrinkles(14).
The testing of high doses of sun-emitted UV-radiation induce reactive oxygen species (ROS) as major pro-oxidants thus inducing premature skin aging, showed a positive effect of Carotenoid-tablets combined with placebo-cream in induced less carotenoid accumulation than carotenoid-tablets alone(15) of that suggested that In contrast to topical application, the systemically applied carotenoids are stored in the body fat tissue and slowly released onto the skin surface with sweat and sebum. Retinaldehyde (RAL) showed a significant improvement of wrinkles(forehead wrinkles, nasolabial folds, crow's feet and perioral wrinkles)(16).In fact, deficiency of vitamin A may result of induced premature aging. In skin of streptozotocin (STZ)-induced type 1 diabetic rats, showed over expression of matrix metalloproteinase -2 (MMP-2) and hyaluronidase (HAase) but not on vitamin A treated mice, through promoting the production of collagen in dermis and inducing cell growth and inhibition of epidermal differentiation in skin tissues(17).
Taken altogether, vitamin A and its variants are found to be effective in prevention of skin damage and skin aging caused by over expression of type I procollagen and under expression of collagenase (matrix metalloproteinases-1, MMP-1).
Recommended intakes of vitamin A, according to the Institute of Medicine of the National Academies (formerly National Academy of Sciences) is 600 µg daily as extremely high doses (>9000 mg) can be toxicity as causes of dry, scaly skin, fatigue, nausea, loss of appetite, bone and joint pains, headaches, etc. As always, all articles written by Kyle J.

Skin aging in Foods points of view
Kyle J. Norton(Draft article)
Skin aging is one of most visible ageing process which occurs constantly in our skin organ. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals, to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin, affect skin elasticity and tightness(a). Other suggested that free radicals induced domino effects in production of reactive oxygen species, can react with DNA, proteins, and fatty acids, causing oxidative damage and impairment of antioxidant system, leading injuries damage regulation pathways of skin, including wrinkles, roughness, appearance of fine lines, lack of elasticity, and de- or hyperpigmentation marks(b).
The degradation of the epidermal and dermal layers of the extracellular matrix (ECM), the non-cellular component present within all tissues and organs, such as UV Exposure, decline of lysosomal/endosomal cathepsin K, S and V activity(c) as well as environment factors such as irregular dryness, dark/light pigmentation, sallowness, severe atrophy, telangiectases, premalignant lesions, laxity, leathery appearance and deep wrinkling, etc., cause modification of the surface of skin and the physical properties of that lead to skin aging. Certain foods have been found to be effective in protect the skin against natural aging, including green tea and garlic.
1. Garlic
Garlic (Allium sativum) is a species in the onion genus, belonging to family Amaryllidaceae, native to central Asia. It has been used popularly in traditional and Chinese medicine in treating common cold and flu to the Plague, blood pressure cholesterol levels, natural antibiotic, etc.
In wrinkle formation, caffeic acid and S-allyl cysteine found in garlic significantly inhibited the degradation of type І procollagen and the expressions of MMPs in vivo and attenuated the histological collagen fiber disorder and oxidative stress in vivo, through decreased oxidative stress and inflammation by modulating the activities of NF-κB and AP-1, and exhibited an indirect anti-oxidant effect by suppressing cyclooxygenase-2 (COX-2) and induced nitric oxide synthase (iNOS) expressions levels and down-regulated transcriptional factors(1). Its garlic's antioxidant properties may either prevent or delay chronic diseases associated with aging(2). According to Aarhus University, garlic not only protected skin cell from undergo aging process but also inhibited the abnormal growth of skin cells, through its on long-term growth characteristics, morphology and macromolecular synthesis of human fibroblasts(3).
2. Ginger
Ginger (Zingiber officinale) or ginger root is the genus Zingiber, belonging to the family Zingiberaceae, native to Tamil. It has been used in traditional and Chinese medicine to treat dyspepsia, gastroparesis, constipation, edema, difficult urination, colic, etc.
In formation of wrinkles induced by UV exposure in rat or hairless mouse skin, extract of Zingiber officinale, significantly inhibited the fibroblast-derived elastase at a suberythemal dose, in prevention of the decrease in skin elasticity in both types of animal skin(4).
3. Black bean
Small roughly ovoid legumes with glossy black shells, genus Phaseolus, belongs to the family Fabaceae and can bought in most grocery stores all around the year in dried and canned forms. It is believed that black bean was first domesticated growth in South America.
According to Jiangnan University, chemical constituents in black bean sprouts may potentiate as additives in anti-aging and whitening skin cosmetic products due to its antioxidant properties(5).
On UVB-induced apoptotic skin cell death, anthocyanins a major chemical compound found in black bean, not only reduced UVB-induced reactive oxygen species levels but also inhibited UVB-induced apoptotic cell death through the prevention of caspase-3 pathway activation and reduction of proapoptotic Bax protein levels(6). Other study also found the effectiveness of anthocyanins in modulation of oxidative disorders including UVB-induced inflammation(7).
4. Avocado
Avocados are a commercially valuable fruit and are cultivated in tropical climates throughout the world, it is a green-skinned, pear-shaped fruit that ripens after harvesting and native to the Caribbean, Mexico, South America and Central America, belonging to the flowering plant family Lauraceae.
Daily intake of one-half a Hass avocado (68 g), may support cardiovascular health, weight management and healthy aging(8). Study on the of ingestion of an unsaponifiable avocado and soya extract (P.I.A.S.) indicated a very probable presence of phytosterols and a richer proportion of cholesterol, precursors particularly methostenol in the skin of rats fed(9).
5. Passion fruit
Passionflower is also known as passion vines,, in the genus Passiflora , belonging to the family Passifloraceae, native to southeastern parts of the America. The herb has been used in traditional medicine in treating nervous tension including anxiety, insomnia, seizures, sleep problems and hysteria.
Passion fruit seed extract, piceatannol, and scirpusin B affected the keratinocyte by upregulated the glutathione (GSH) levels in keratinocytes in a dose-dependent manner, suppressed the UVB-induced generation of reactive oxygen species (ROS), and enhanced matrix-metalloproteinase (MMP)-1 activity(10). A flavone chrysin from Passiflora caerulea Linn. and a benzoflavone moiety (BZF) recently isolated from Passiflora incarnata Linn in rat skin study, showed a great potential for clinical and therapeutic applications against the physiological and biochemical effects of aging(11).
6. Mango
Mango tree is a flower plant of genus of Mangifera, belonging to the family Anacardiaceae, native to the subtropical and tropical southeast Asia. The
Beide exerting its antioxidant with anti-inflammatory and immunomodulatory activities, mango extract showed to inhibit wrinkle formation and damage to collagen fiber against UVB-induced skin aging in hairless mice(12). Polyamine, a major chemical constituent of mango and other plants may be potential target for reduced aging skin as the level of spermidine was maximal in 10-week-old mice and markedly reduced in 26-week-old mice(13).
7. Apple
Apple is the pomaceous fruit of the apple tree, a species of the rose family Rosaceae. It is one of the most widely cultivated tree fruits. The tree is originated in Central Asia.
Apple whole fruit and its chemical compound showed to protect cells from aging through influence aging and oxidative stress(14). The study from Taipei Medical University, in the study of its chemical compounds suggested the use of extract of M. doumeri var. formosana (containing phenolic compounds) in anti-aging or cosmetic products(15) through exhibition of anti-oxidant and tyrosinase reducing activities(16).
9. Sea buckthorn fruit
Sea buckthorn is a shrub in the genus Hippophae, belonging to the family Elaeagnaceae, native to in
the wide regions of the Atlantic coasts of Europe right across to northwestern Mongolia and also
northwestern China.
A sea buckthorn (Hippophae rhamnoides L.) fruit blend (SFB) containing sea buckthorn fruit extract,
exhibited a protective and therapeutic drug candidate against skin aging by regulating the moisture
content, MMP expression levels and SOD activity in UV radiation-induced skin aging in hairless mice,
according to the study by the Pusan National University(17).
10. Grape
Grape is a woody vines of the genus Vitis, belong to the family Vitaceae, native to southern Turkey.
Trans-resveratrol, a polyphenol extracted from grape, showed a remarkable improvement in decreased aging signs(18). In facial skin morphology and functionality, combination of grape seed extract and soy phospholipids showed to have the potential in induced signal transduction pathways in facial hypodermis, resulting in anti-aging effects throughout all skin compartments, including dermal and epidermal layers(19). Clinically and biometrically, composition of lycopene, acerola extract, grape seed extract and Biomarine ComplexT showed to increase parameters of cutaneous hydration, reduction of pH, ultrasound density and a histological increment of collagen and elastic fibers (both on the face and arm), through a reduction of seborrhea (only on the face)(20).
11. Pomegranate
Pomegranates is a fruit-bearing small tree, genus Punica, belonging to family Lythraceae, native to Iran but has been cultivated in Asian since ancient time.
Pomegranate are among many plants ma be beneficial in protect against human skin aging(21), In the
study at the Kyung Hee University Global Campus, Punica granatum (pomegranate) extract showed a positive effect in protecting skin against UVB-induced damage in cultured human skin fibroblasts, through increased expression of procollagen type I and decreased expression of MMP-1(22). In an immortal human keratinocyte line (Hala cell line), pomegranate polyphenol extract POMx protected HaCaT cells against UVB-induced oxidative stress and markers of photoaging(23). Ellagic acid, a polyphenol compound presented in berries and pomegranate, prevented collagen destruction and inflammatory responses caused by UV-B, according to the Hallym University(24).
12. Almond skin
Almond consists of an outer hull and a hard shell with the seed (nut) inside is native to the Middle East. It is most widely cultivated seed in the world for it economic and health benefit.
The study of α-Tocopherol (AT) and polyphenols (AP) present in almonds ahainst UV exposure causes of oxidative stress, inflammation, erythema, and skin cancer, showed the positive effect of AT and AP, applied to medium or topically, in photoprotection against UVA(25)(26).
13. Cacao bean and cola nut
Caocao a small tropical American evergreen tree, of the genus Theobroma, belonging to the family Malvaceae. Its seed has been used for making chocolate and cocoa mass, cocoa powder.
Cola tree is a genus Cola, belonging the family Malvaceae, native to the tropical rainforests of Africa.
Topical application of plant extracts and their xanthine derivatives showed to suppressed wrinkle formation, dermal connective alteration, and collagen accumulation(27). The 1Natura Innovation and Product Technology Ltda, Cajamar study indicated the antioxidant effects of cacao in protection against oxidative causes of skin cell damage(28).
14. Olive oils
Olive is belongs to the the family Oleaceae, native to the coastal areas of the eastern Mediterranean Basin and south end of the Caspian Sea. Its fruit, is also called the olive and the source of olive oil.
Unsaturated fatty acid (PUFA) found abundantly in olive oil may be effective in alleviation of skin problems such as dryness and those related to the aging process. The Università degli Studi di Torino study showed the use of combination of hemp seed and olive oils may inhibit the problem through spraying in some gel-emulsions(29). According to the Procter & Gamble Company, olive-derived fatty acid ethoxylates, not only showed to restore antioxidant enzymes in skin keratinocytes and fibroblasts, but also reduced melanin production by an adrenergic receptor mechanism in melanocytes(30).
15. Date palm kernel extract
Date palm tree is a genus of Phoenix, belonging to the family Arecaceae, native from lands around Iraq. According to Vincience Research Center Date palm kernel
extract, in the study of 10 Ten healthy women volunteers, between the ages of 46 and 58 years, applied
the cream formula with 5% date palm kernel or placebo on the eye area twice a day for 5 weeks,
application of date palm kernel reduced the total surface of wrinkles by 27.6% (p = 0.038), the depth of
wrinkles by 3.52% (p = 0.0231). These results are statistically significant and were clinically confirmed
where visual improvement was seen in 60% of the volunteers treated(31).
16. Lemon oil
Lemon is a species of Citrus Aurantifolia, belongs to the family Rutaceae. It has around shape are with green to yellow in color and 3–6 cm in diameter and native to Southeast Asia.
According to University of Catania, Italy, a natural compound isolated from lemon oil (Lem1) not only showed to significantly increase the antioxidative potential of skin biosurface in healthy volunteers and a strong antioxidant effects in inhibition of free radical-mediated reactions, as evaluated in vitro and in vivo(32) and may provide a better understanding of the endogenous antioxidant potential of skin and the real validity of a natural antioxidant biotechnology in the antiaging management of the skin(33).
Taken altogether, the list of foods have been found effectively in protection of photoagingnd alleviation of skin symptoms due to aging, as well as through influence of the expression of procollagen type I and MMP-1.

Clinically and biometrically, composition of lycopene, acerola extract, grape seed extract and Biomarine ComplexT showed to increase parameters of cutaneous hydration, reduction of pH, ultrasound density and a histological increment of collagen and elastic fibers (both on the face and arm), through a reduction of seborrhea (only on the face)(20).
11. Pomegranate
Pomegranates is a fruit-bearing small tree, genus Punica, belonging to family Lythraceae, native to Iran but has been cultivated in Asian since ancient time.
Pomegranate are among many plants ma be beneficial in protect against human skin aging(21), In the
study at the Kyung Hee University Global Campus, Punica granatum (pomegranate) extract showed a positive effect in protecting skin against UVB-induced damage in cultured human skin fibroblasts, through increased expression of procollagen type I and decreased expression of MMP-1(22). In an immortal human keratinocyte line (Hala cell line), pomegranate polyphenol extract POMx protected HaCaT cells against UVB-induced oxidative stress and markers of photoaging(23). Ellagic acid, a polyphenol compound presented in berries and pomegranate, prevented collagen destruction and inflammatory responses caused by UV-B, according to the Hallym University(24).
12. Almond skin
Almond consists of an outer hull and a hard shell with the seed (nut) inside is native to the Middle East. It is most widely cultivated seed in the world for it economic and health benefit.
The study of α-Tocopherol (AT) and polyphenols (AP) present in almonds ahainst UV exposure causes of oxidative stress, inflammation, erythema, and skin cancer, showed the positive effect of AT and AP, applied to medium or topically, in photoprotection against UVA(25)(26).
13. Cacao bean and cola nut
Caocao a small tropical American evergreen tree, of the genus Theobroma, belonging to the family Malvaceae. Its seed has been used for making chocolate and cocoa mass, cocoa powder.
Cola tree is a genus Cola, belonging the family Malvaceae, native to the tropical rainforests of Africa.
Topical application of plant extracts and their xanthine derivatives showed to suppressed wrinkle formation, dermal connective alteration, and collagen accumulation(27). The 1Natura Innovation and Product Technology Ltda, Cajamar study indicated the antioxidant effects of cacao in protection against oxidative causes of skin cell damage(28).
14. Olive oils
Olive is belongs to the the family Oleaceae, native to the coastal areas of the eastern Mediterranean Basin and south end of the Caspian Sea. Its fruit, is also called the olive and the source of olive oil.
Unsaturated fatty acid (PUFA) found abundantly in olive oil may be effective in alleviation of skin problems such as dryness and those related to the aging process. The Università degli Studi di Torino study showed the use of combination of hemp seed and olive oils may inhibit the problem through spraying in some gel-emulsions(29). According to the Procter & Gamble Company, olive-derived fatty acid ethoxylates, not only showed to restore antioxidant enzymes in skin keratinocytes and fibroblasts, but also reduced melanin production by an adrenergic receptor mechanism in melanocytes(30).
15. Date palm kernel extract
Date palm tree is a genus of Phoenix, belonging to the family Arecaceae, native from lands around Iraq. According to Vincience Research Center Date palm kernel
extract, in the study of 10 Ten healthy women volunteers, between the ages of 46 and 58 years, applied
the cream formula with 5% date palm kernel or placebo on the eye area twice a day for 5 weeks,
application of date palm kernel reduced the total surface of wrinkles by 27.6% (p = 0.038), the depth of
wrinkles by 3.52% (p = 0.0231). These results are statistically significant and were clinically confirmed
where visual improvement was seen in 60% of the volunteers treated(31).
16. Lemon oil
Lemon is a species of Citrus Aurantifolia, belongs to the family Rutaceae. It has around shape are with green to yellow in color and 3–6 cm in diameter and native to Southeast Asia.
According to University of Catania, Italy, a natural compound isolated from lemon oil (Lem1) not only showed to significantly increase the antioxidative potential of skin biosurface in healthy volunteers and a strong antioxidant effects in inhibition of free radical-mediated reactions, as evaluated in vitro and in vivo(32) and may provide a better understanding of the endogenous antioxidant potential of skin and the real validity of a natural antioxidant biotechnology in the antiaging management of the skin(33).
Taken altogether, the list of foods have been found effectively in protection of photoagingnd alleviation of skin symptoms due to aging, as well as through influence of the expression of procollagen type I and MMP-1.

Benign prostatic hyperplasia(BPH) in Vitamin E Points of View
Benign prostatic hyperplasia(BPH) is defined as a condition of increased in the number of cells of prostate gland, causing partial, or sometimes virtually complete obstruction of the urinary tract. According to statistic, BPH commonly starts at age of 30 and symptoms usually can not be realized until age of 50. More than half of men between age of 60-70 are experience symptoms of BPH and only 10% are required treatment.
Vitamin E, a fat soluble vitamin, consisting eight different variants (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) with varying levels of biological activity(2), found abundantly in corn oil, soybean oil, margarine, wheat germ oil, sunflower,safflower oils, etc. plays an important role in neurological functions and inhibition of platelet aggregation, regulation of enzymatic activity, free radical scavenger, etc..
Epidemiological studies, linking vitamin E in reduced risk and treatment of benign prostatic hyperplasia have not been consistent(1)(2)(3).
A composition, consisting cernitin, saw palmetto, B-sitosterol, vitamin E has shown to significantly reduce nocturia and frequency and diminish overall symptomatology of BPH, according to the Georgetown University Medical Center(4). Some researchers suggested that Benign prostatic hypertrophy (BPH) may be associated to the long-term exposure of the prostate to the strong androgen 5alpha-dihydrotestosterone (DHT) due to aging induced conversion of free testosterone and food supplementation with extracts of Serenoa repens and a combination of the antioxidants selenium, (cis)-lycopene and natural vitamin E, together with fish oil rich in long-chain polyunsaturated essential fatty acids of the omega-3 group may be effective as pharmaceutical 5alpha-reductase inhibitors in partial androgen deficiency correct testosterone substitution(5). Vitamin E, as an antioxidant and free radical scavenger may be effective in reduced oxidative stress as patients with BPH were found with significant decrease in plasma alpha-Toc and Asc level(6)(7). Although diet and dietary supplement intervention appeared to slow BPH progression, over consumption of dietary supplements may be harmful(8).
Taking altogether, without going into reviews, vitamin E may be effective in reduced risk and treatment of patients with BPH. Over doses of vitamin E supplement can cause symptoms of blurred vision, weakness, dizziness, nausea, diarrhea, etc., please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Benign prostatic hyperplasia(BPH) in Vitamin D Points of View
By Kyle J. Norton
Benign prostatic hyperplasia(BPH) is defined as a condition of increased in the number of cells of prostate gland, causing partial, or sometimes virtually complete obstruction of the urinary tract. According to statistic, BPH commonly starts at age of 30 and symptoms usually can not be realized until age of 50. More than half of men between age of 60-70 are experience symptoms of BPH and only 10% are required treatment.
Vitamin D is a fat-soluble secosteroids found in small amount in few foods, including salmon, mackerel, sardines and tuna. The vitamin plays an important role in modulation of cellular proliferation, apoptosis induction, tumor growth suppression and promotion in absorption of minerals, including calcium, iron, magnesium, phosphate and zinc.
Epidemiological studies, focusing the use of dietary vitamin E in reduced risk of benign prostatic hyperplasia(BPH) have produced inconsistent results(a)(b).
1. Vitamin D receptor(VDR) and BPH
The study of 222 prostate cancer patients, 209 benign prostatic hyperplasia (BPH) patients, 128 male controls who were over 60 years old and without any evidence of prostate cancer or BPH, and 198 female controls in Japanese men to exp;ore the genetic mutation of polymorphism in the VDR gene for risk of prostate cancer and BPH found the positive effect of BsmI polymorphism in the VDR gene in protection against prostate cancer(1). Other study showed rs731236 variant of the vitamin D receptor had a protective effect for LUTS, a common symptoms of men with BPH(2), and VDR Fok I polymorphisms may be correlated with BPH complicated by histological prostatitis, the study of Graduate School, South Medical Universit showed(3). In Indian population, Taq-I and Bsm-I genetic variants of VDR gene influence susceptibility BPH(4). But in the study of polymorphims with functional significance in the Bsm, Apa 1 and Taq 1 genes were therefore compared in 28 prostate cancer (CaP), 44 benign prostate hyperplasia (BPH) and 30 control cases in Thailand, indicated no significant variation in distribution of these three groups. Of that suggested these variations in the distribution frequencies from country to country and depending to other factors such as sun exposure, dietary and other lifestyle factors(5).
2. The serum of Vitamin D
Some researchers suggested that serum of vitamin D may be an indication of early onset of benign prostatichyoerplasia BPH. According to the study by American Urological Association Education and Research, low levels of 25-OH vitamin D is associated with benign prostatic hyperplasia(6). But a study by Democritus University of Thrace showed no clear relationship between vitamin D and serum levels of PSA or-of f/t-PSA in PD patients(7).
3. The effects
BPH(1). BXL-628. a vitamin D3 analog, showed to decrease prostate growth and BPH symptoms, through inhibition of cell migration and cytoskeleton remodeling in altered bladder contractility associated with BPH-induced lower urinary tract symptoms(8). Elocalcitol, a vitamin D3 analog, reduced the static component of BPH by inhibiting the activity of intraprostatic growth factors downstream of the androgen receptor, by targeting the RhoA/ROCK and NF-kappaB pathway(9). The New York University School of Medicine study showed increase intake of vitamin D impact an adverse correlation with decreased BPH prevalence(10). Another novel nonsecosteroidal VDR agonist (CH5036249) showed an cell growth inhibitory activity of CH5036249 to be comparable to that of 1alpha,25(OH)2D3(11). Other analogs, including BXL-353, may also be potential for patients with BPH(12).
Taking altogether, serum of vitamin D may not be realizable diagnosis in determine the early onset of BPH, but Vitamin D analogs are associated to reduced risk and treatment of Benign prostatic hyperplasia(BPH).

Benign prostatic hyperplasia(BPH) in Vitamin A Points of View
Benign prostatic hyperplasia(BPH) is defined as a condition of increased in the number of cells of prostate gland, causing partial, or sometimes virtually complete obstruction of the urinary tract. According to statistic, BPH commonly starts at age of 30 and symptoms usually can not be realized until age of 50. More than half of men between age of 60-70 are experience symptoms of BPH and only 10% are required treatment. Epidemiological studies, linking herbal medicine in reduced risk of benign prostate hyperplasia have produced a certain positive result, but multi centers and large sample size to identify the principle ingredient and to validate these result are necessary.
Vitamin A is a general term of Vitamin A Retinol, retinal, beta-carotene, alpha-carotene, gamma-carotene, and beta-cryptoxanthin best known for its functions for vision health and antioxidant scavenger and essential for growth and differentiation of a number of cells and tissues.
Recommended intakes of vitamin A, according to the Institute of Medicine of the National Academies (formerly National Academy of Sciences) is 600 µg daily as extremely high doses (>9000 mg) can be toxicity as causes of dry, scaly skin, fatigue, nausea, loss of appetite, bone and joint pains, headaches, etc.
1. Retinols
Vitamin A (retinol) and its derivatives, the retinoids concentration was 2-fold elevated in BPH compared with the tissues of normal prostate, and prostate carcinoma tissues of that may be an indication of role of retinoids in the physiology of the prostate and possibly also in the pathophysiology of prostate cancer(1). In human INSL3 in patients with benign prostate hyperplasia (BPH), all-trans-retinoic acid showed to up-regulate LGR8 gene activity in a dose- and time-dependent manner while having no effect on INSL3 gene activity(2). the study of the effects of 9-cis retinoic acid (9cRA) in suppressing prostate cell proliferation (PECP) and carcinogenesis in p27(Kip1) deficient mice, showed that 9cRA suppress prostate intraepithelial neoplasia (PIN) in all three p27(a cell cycle suppressor gene) genotypes through decreased suppress prostate cell proliferation (PECP) and increased cellular senescence(3).
2. Carotenoids(beta-carotene, alpha-carotene, gamma-carotene and beta-cryptoxanthin) Carotenoids, plant pigments, converted to vitamin A after intake, play an important role in prevention and treatment of some diseases through its antioxidant effects. Dietary carotenoids risk of BPH and prostate cancer is associated to age and fat intake. The study of 100 patients with prostate cancer and two different control series [100 benign prostatic hyperplasia (BPH) patients and 100 general hospital patients] showed a risk differentiation of reduction by dietary beta-carotene and vitamin A was significant in the older men (70-79 years), but not in the younger men (50-69 years) with protective effect against prostate cancer related to the low overall fat intake in Japan(4). According to Johns Hopkins Bloomberg School of Public Health, consumption of fruit and vegetables rich in beta-carotene was inversely related to BPH(5)(6).
The Kyoto University study, in a case-control study of prostatic cancer and BPH, consisted of 100 patients with prostatic cancer, matched for hospital, age (+/- 3 yr) and hospital admission date (+/- 3 months) to patients with benign prostatic hyperplasia (BPH) and hospital controls indicated a correlation of daily intake of beta-carotene (RR = 2.13: 1.20-3.77), as compared with hospital controls, were significantly correlated with prostatic cancer development(7). Lower concentration of of carotenoids, may be an indication of disease progression rather than the systemic inflammatory response in patients with prostate cancer reported by the 1University Department of Surgery, Royal Infirmary(8). Unfortunately, according to Kyoto Prefectural University of Medicine, serum beta-carotene and smoking are associated to increased risk with the development of BPH(9).
Taking altogether, although controversial, vitamin A may be associated to reduced risk of BPH but further large sample size studies are necessary to clarify it effectiveness. Overdoses can lead to toxic symptoms. Please make sure you follow the guideline of the Institute of Medicine of the National Academies. As always, all articles written by Kyle J.
