Skin aging in Vitamin B3 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).
Niacin, is also known as vitamin B3, nicotinic acid, an organic compound with the formula
C6H5NO2, found abundantly in chicken, beef, fish, cereal, peanuts and legumes. It is best known for its effects in lowering cholesterol and triglycerides and removing toxic from our body and promoting production of steroid hormones.

Vitamin B3 may be effective to protect against skin-aging through its antioxidant activity(1)(2)(3) such as allowness, wrinkling, red blotchiness and hyperpigmented spots(3a)
In the comparison of the effect on aging skin among  a cosmetic niacinamide/peptide/retinyl propionate product regimen vs. a prescription 0.02% tretinoin product regimen, researchers at the showed that the composition significantly improved wrinkle appearance after 8 weeks relative to tretinoin, with comparable benefits after 24 weeks with well tolerate adverse effects(4). In facial hyperpigmentation, composition of topical niacinamide and N-acetyl  reduced the appearance of irregular pigmentation including hypermelaninization(5) and niacinamide alone enhanced skin lightening, and hyperpigmented lesions(6) through inhibiting melanosome transfer from melanocytes to keratinocytes(7).  A daily facial lotion application containing vitamins B3 and E and provitamin B5 on the facial skin of Indian women, 30-60 years of age, for 10 weeks, showed a significantly reduced appearance of hyperpigmentation, improved skin tone evenness, appearance of lightening of skin, and positive effects on skin texture, as early as 6 weeks(8). In Global gene expression skin aging process, compounds niacinamide and hexamidine, may effect the skin hydration, barrier, matrix, pigmentation through theirs' antioxidant capacity(9). According to Kinki University School of Medicine, application of composition containing 4%  niacinamide in 30 healthy Japanese females who had wrinkles in the eye areas showed to reduced wrinkles in the eye areas through a marked and moderate improvement in 64% of the subjects with a significant difference as compared with the control site(10) and niacinamide aloneexhibited a significant reductions in fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness (yellowing)(11)(12).

Taken altogether, strong evidence suggested that vitamin B3 used alone or combination with other antioxidants may be beneficial in reduced the early onset skin aging and skin aging progression.  Overdoses of vitamin B3 may induce symptoms of severe skin flushing combined with dizziness, rapid heartbeat, itching, nausea, vomiting, abdominal pain, etc. As always,  all articles written by Kyle J.
