Rating (out of 5): 3

Vitamin E, specifically in the form of mixed tocotrienols, has some scientific support for its use in managing dry and/or flaky skin, though the bulk of evidence is moderate and more robust for alpha-tocopherol than for tocotrienols. Vitamin E is a fat-soluble antioxidant that helps protect cell membranes from oxidative damage, which can contribute to skin barrier dysfunction and dryness. Topical application of vitamin E (mainly alpha-tocopherol, the most studied form) has been shown in several clinical and laboratory studies to improve skin hydration, enhance barrier function, and reduce transepidermal water loss. These effects can help alleviate dry and flaky skin.

While oral supplementation of vitamin E also contributes to overall skin health, the direct evidence for oral tocotrienols specifically improving dry skin is limited. Most studies and dermatological formulations focus on topical vitamin E (including both tocopherols and tocotrienols), where its antioxidant, anti-inflammatory, and moisturizing properties help reduce irritation and improve skin texture. Some small clinical studies and animal research suggest tocotrienols may be even more potent antioxidants than tocopherols, but high-quality, large-scale clinical trials in humans are lacking.

In summary, scientific evidence moderately supports the topical use of vitamin E, including tocotrienols, for dry/flaky skin, while oral tocotrienols require more research for this specific application. The ingredient is widely used in dermatological products for its established role in supporting skin barrier function and hydration.
