Rating (out of 5): 3

Vitamin E is commonly used in skin care products for its antioxidant properties. Scientific research has provided moderate evidence supporting its role in protecting the skin from oxidative stress caused by environmental factors such as UV radiation and pollution. Vitamin E (tocopherol) neutralizes free radicals, helping to prevent cellular damage in the skin. Several in vitro and animal studies demonstrate that topical vitamin E can reduce UV-induced skin damage and inflammation. Some small human studies suggest that vitamin E may improve skin texture, reduce signs of aging, and enhance wound healing, especially when combined with other antioxidants like vitamin C. However, evidence from large, well-controlled clinical trials in humans is limited, and results are often mixed regarding its efficacy in treating scars, stretch marks, or chronic skin conditions.

Historically, vitamin E has been used in cosmetics and topical formulations for decades, largely based on its reputation as a "skin vitamin." It is generally considered safe for most people when applied to the skin, though there is a risk of allergic reaction in some individuals. Overall, while the scientific evidence is not overwhelmingly robust, it does support the use of vitamin E in maintaining general skin health, primarily through its antioxidant effects and potential to support the skin barrier.
