Rating (out of 5): 3

Vitamin E (tocofersolan) is commonly used in dermatological products to support or treat dry and/or flaky skin. The scientific rationale for its use is based on Vitamin E's role as a lipid-soluble antioxidant, which can help protect skin cell membranes from oxidative damage induced by environmental stressors such as UV radiation. Tocofersolan, a water-soluble derivative of Vitamin E, is particularly valued for its improved bioavailability and formulation properties in topical and oral products.

Clinical studies and dermatological literature provide moderate evidence for the moisturizing and barrier-supporting effects of Vitamin E in topical preparations. For example, topical Vitamin E has been shown to enhance skin hydration, reduce transepidermal water loss, and support the integrity of the stratum corneum (the skin's outermost layer). It is also frequently included in formulations for conditions like atopic dermatitis and xerosis (abnormally dry skin). However, the evidence is mixed regarding its superiority over other emollients, and most studies highlight its benefit primarily as part of multi-ingredient formulations rather than as a standalone therapy.

Overall, the use of Vitamin E (including tocofersolan) for dry or flaky skin is supported by plausible mechanisms and some clinical data, but high-quality, large-scale trials are limited. Its effectiveness is considered moderate, especially in cases of mild to moderate dryness, and it is generally regarded as safe for topical use.
