Rating (out of 5): 2

Vitamin E (including mixed tocopherols and tocotrienols) has been investigated for its role in skin health and as a supportive treatment for dermatitis, particularly atopic dermatitis. Scientific evidence supporting its use is limited but present, primarily from small clinical trials and animal studies. Vitamin E acts as an antioxidant, which may help reduce oxidative stress and inflammation in the skin—both factors in dermatitis pathogenesis.

Some small randomized controlled trials (RCTs) have shown that oral vitamin E supplementation can reduce symptoms of atopic dermatitis, such as itching and severity scores, when compared to placebo. For example, a double-blind RCT published in the International Journal of Dermatology (2015) found that oral vitamin E (400 IU daily) improved eczema severity scores over 8 months. There is also in vitro and animal evidence suggesting that vitamin E can reduce inflammatory markers and skin barrier disruption.

However, the overall quality and quantity of evidence is modest. Most studies are small, of limited duration, and often use vitamin E in combination with other antioxidants, making it difficult to isolate its effects. Topical vitamin E is also sometimes used, but evidence for its effectiveness is weaker and there are reports of contact dermatitis in some individuals. Major dermatology guidelines do not currently recommend vitamin E as a first-line therapy for dermatitis.

In summary, there is scientific—though limited—evidence that vitamin E may help support dermatitis management, but it is not considered a primary or standalone treatment.
