Rating (out of 5): 2

Vitamin E, including mixed tocotrienols, has been studied for its role in supporting skin health, particularly in conditions of dryness and flakiness. Vitamin E is a lipid-soluble antioxidant that helps protect cell membranes from oxidative stress, which is relevant because oxidative damage can impair skin barrier function. There is evidence from in vitro and animal studies suggesting that tocotrienols, a form of vitamin E, possess higher antioxidant activity than tocopherols, potentially offering more pronounced protective effects for the skin.

Human studies investigating the topical and oral use of vitamin E for dry or flaky skin are limited and the results are mixed. Some small clinical trials and case series have shown that topical vitamin E (usually as alpha-tocopherol) can improve skin hydration and reduce symptoms of dryness, but robust studies with tocotrienol-rich formulations are lacking. Most over-the-counter skin products use tocopherol rather than tocotrienols, so direct evidence for mixed tocotrienols is sparse.

Overall, while there is some biological plausibility and preliminary evidence that vitamin E (including tocotrienols) may help support skin barrier function and reduce dryness, high-quality clinical trials are lacking. The use of vitamin E for dry or flaky skin is therefore supported by limited scientific evidence, warranting a moderate-low rating.
