According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals, protect the skin matrix through the inhibition of enzymatic degradation, or promote collagen synthesis in the skin, affecting skin elasticity and tightness(1).
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 the skin, including wrinkles, roughness, the appearance of fine lines, lack of elasticity, and de- or hyperpigmentation marks(2).
Vitamin E may have a substantial and therapeutic effect in reducing major signs of aging, some scientists suggested.
The results were published by a number of respectable institutes, including Universiti Kebangsaan Malaysia and University of Ljubljana,
Vitamin E, a fat-soluble vitamin, consisting of eight different variants (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) with varying levels of biological activity, 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..
According to the Universiti Kebangsaan Malaysia, in stress-induced premature senescence (SIPS) model of human diploid fibroblasts (HDFs), γ-tocotrienol (GTT), a vitamin E variant showed to delay cellular senescence of human diploid fibroblasts through the inhibition of intrinsic mitochondria-mediated pathway which involved the regulation of pro- and anti-apoptotic genes and proteins(3) and prevented cellular aging in human diploid fibroblasts(4), probably through modulating gene expression(5) and protected against oxidative stress-induced cellular aging by modulating the telomere length possibly via telomerase(6).
The molecular mechanism of the tocotrienol-rich fraction (TRF) study insisted that the variants protect against H(2)O(2)-induced oxidative stress in human skin fibroblast culture by modulating the expression of Skin Aging in COL I and COL III genes(Collagen gene) with a concomitant increase in the rate of total collagen synthesis(7).
According to the National University of Malaysia, f alpha-tocopherol (ATF), another variant of vitamin E protected against H(2)O(2)-induced DNA damage and telomere shortening of normal human skin fibroblast cells derived from young and old individual donors(8).
Topical administration of alpha-tocopherol (ATF), in medium doses, may provide some degree of photoprotection against UVA(9).
Some researchers suggested the potential of vitamins in reduced aging progression is a result of the balance between various skin antioxidants of vitamins E and C, through new delivery systems in the induction of delivering vitamins C and E into the skin simultaneously(10).
Other antioxidants such as vitamin E, certain flavonoids, and the carotenoids, β-carotene, lycopene, and lutein, found in healthy foods may also improve skin health through protection against inflammation, oxidative stress, breakdown of the extracellular matrix(11).
In Indian women with facial signs of aging study, the composition of niacinamide, panthenol, and tocopheryl acetate significantly reduced appearance of hyperpigmentation, improved skintone evenness, appearance of lightening of skin, versus control in 6 weeks(12).
Taken together, the composition of vitamin E and other antioxidants and their variants may be effective
in reduced early onset of skin aging and inhibited skin aging progression, but large sample size and multi centers studies to improve this validation are necessary.
Overdoses of vitamin E supplements 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.
