Vitamin E (specifically vitamin E acetate, or tocopheryl acetate) has some scientific evidence supporting its use in the management of dermatitis, though the evidence is limited and not robust. Vitamin E is known for its antioxidant properties, which may help protect skin cells from oxidative stress and support skin barrier function. Several small clinical studies and case reports have explored topical vitamin E in various forms of dermatitis, including atopic dermatitis and contact dermatitis. Some studies suggest that topical application may reduce symptoms such as itching, erythema, and edema, likely due to its anti-inflammatory and skin-protective effects.

However, the studies are generally small, sometimes open-label, and often combine vitamin E with other agents, making it difficult to attribute effects solely to vitamin E. There is also variability in formulations (e.g., vitamin E acetate vs. tocopherol) and dosages used. Oral vitamin E has less evidence for efficacy in dermatitis and is not widely recommended for this purpose. Topical vitamin E is more commonly used, but high-quality randomized controlled trials are lacking. Vitamin E acetate is favored in topical products for its stability and relative safety.

In summary, while there is some scientific backing for the topical use of vitamin E (including vitamin E acetate) in dermatitis, the quality and quantity of evidence are limited, and its use is better supported as adjunctive or supportive rather than primary therapy. More rigorous clinical trials are needed to firmly establish its efficacy for dermatitis.
