Rating (out of 5): 3

Vitamin E, particularly in the form of alpha-tocopheryl succinate, is widely used in skin care due to its well-documented antioxidant properties. Scientific evidence supports its role in protecting skin cells from oxidative stress caused by environmental factors such as UV radiation and pollution. As a fat-soluble antioxidant, Vitamin E helps neutralize free radicals that can damage skin lipids, proteins, and DNA, thereby contributing to the maintenance of healthy skin and potentially slowing visible signs of aging. Several in vitro and animal studies have demonstrated that alpha-tocopherol and its esters (including alpha-tocopheryl succinate) reduce lipid peroxidation and inflammation in the skin. Clinical studies in humans have shown that topical and oral Vitamin E may improve skin hydration, enhance wound healing, and reduce the erythema (redness) associated with UV exposure, though results are sometimes mixed and often depend on the formulation and concentration used.

Despite the positive findings, limitations exist: some clinical trials have failed to show significant benefits for certain skin conditions, and bioavailability of esterified forms (like the succinate) may vary. However, the overall body of evidence supports a beneficial, though moderate, role for Vitamin E in general skin care, particularly as an adjunct to other treatments and as part of a broader antioxidant strategy. Its use is therefore justified by scientific validation, though the strength of evidence is not maximal.
