Scientists may have found a natural and potent herbal plant used for the delay of skin aging, according to the studies.
Skin aging is a natural and biological process of the human which can be stopped.
Long-term free radical damage to the skin through oxidative stress is the major cause of skin aging.
Exposure to the sun (photoaging) and pollution, and loss of subcutaneous support (fatty tissue between your skin and muscle) are some of the risk factors associated with the skin aging.
Some researchers suggested that skin expression may be considered as a refect of the general health of an individual. An unhealthy skin due to skin nutritional deficiency has been a target by the dermatology and cosmetic industries.
Dr.Silke K. Schagen in the study that links between nutrition and skin aging, said, "Vitamins, carotenoids, tocopherols, flavonoids and a variety of plant extracts have been reported to possess potent antioxidant properties and have been widely used in the skin care industry either as topically applied agents or oral supplements in an attempt to prolong youthful skin appearance".
The results strongly suggested that by providing enough nutrition to the skin needs, extrinsic causes of skin aging can be delayed
In skin wrinkle, according to the results of the studies by the Monash University, Melbourne, a high intake of certain food groups are associated with the speeding up of wrinkle, including meat, dairy, and butter. High intake of vegetables, legumes and olive oil appeared to be protective against cutaneous actinic damage.
Aloe Vera is species of succulent plant in the genus Aloe, belonging to the Family Xanthorrhoeaceae, native to Sudan. It has become very popular for commercial cultivation due to its health benefits.
The herbal plant has been used in herbal medicine in treating many kinds of disease, including wound, burn healing, minor skin infections, sebaceous cysts, diabetes, and elevated cholesterol, etc. It is also one of many popular herbs studied in scientific ways with some conflicting results.
The ten main areas of chemical constituents of Aloe vera include amino acids, anthraquinones, enzymes, minerals, vitamins, lignins, monosaccharide, polysaccharides, salicylic acid, saponins, and sterols.
They all work together in a synergistic way to create healing and health-giving benefits, according to Gertrude Baldwin in the article of THE BENEFITS OF THE USE OF ALOE VERA IN HERBAL PREPARATIONS.
With an aim to find a natural ingredient or whole food for the delay of skin aging researchers at the Seoul National University Boramae Hospital examined the effect of aloe gel on the clinical signs and biochemical changes of aging skin.
The experiment included 30 healthy female subjects over the age of 45 given 2 different doses (low-dose: 1,200 mg/d, high-dose: 3,600 mg/d) of aloe vera gel supplementation for 90 days with their baseline status as a control.
Aloe gel intake, the facial wrinkles improved significantly (p<0.05) in both groups, and facial elasticity improved in the lower-dose group.
The injection of the gel also increased the skin photoprotection and the type I procollagen mRNA levels in controlling the rate of procollagen synthesis.
The results were accompanied by the matrix (MMP-1) mRNA levels associated with the breaking down the interstitial collagens, types I, II, and III, particularly in the higher-dose group.
Type I procollagen was substantially increased throughout the dermis in Aloe treatment of the group.
Dr. Cho S, the lead scientist said, "Aloe gel significantly improves wrinkles and elasticity in photoaged human skin, with an increase in collagen production in the photoprotected skin and a decrease in the collagen-degrading MMP-1 gene expression".
The Kyung Hee University Global Campus in the investigation of the effects of Aloe vera on ultraviolet (UV) irradiation induces photo-damage of the skin, which in turn causes depletion of the dermal extracellular matrix and chronic alterations in skin structure.
By the comparison of the baby Aloe shoot extract (BAE, immature aloe extract), which is from the one-month-old shoots of Aloe vera, and adult aloe shoot extract (AE), which is from the four-month-old shoots of Aloe vera, protective effect on UVB-induced skin photoaging in normal human dermal fibroblasts (NHDFs). researchers found that NHDF cells treated UVB-irradiation suppressed the matrixes associated with the breaking down the interstitial collagens, types I, II, and III, and the levels of inflammatory cytokines similar to that of the above study, compared to the AE-treated cells.
BAE treatment elevated type I procollagen which was reduced in photodamaged skin. mediated by the increasing levels of TGF-β1 levels which is a multifunctional cytokine.
The findings clearly suggested that herbal Aloe vera may be considered an anti-aging functional remedy with no side effects.
