Vitamin E has been studied for its role in supporting skin health, including in conditions like dermatitis. Topical vitamin E has antioxidant and anti-inflammatory properties that are thought to help reduce oxidative stress and inflammation, which are central features of many types of dermatitis, such as atopic dermatitis and contact dermatitis. Several small studies and clinical trials suggest that vitamin E—particularly in topical formulations—may provide modest benefit in alleviating symptoms like itching, redness, and scaling. For example, a randomized controlled trial published in the "International Journal of Dermatology" (2015) reported that oral vitamin E supplementation led to a significant improvement in eczema severity compared to placebo. Other studies have examined topical use and found it may speed healing and decrease inflammation in some cases.

However, the evidence base is limited by small sample sizes, short follow-up, and methodological weaknesses. Not all studies have found significant benefits, and there is variation in results depending on the formulation (oral vs. topical), dose, and type of dermatitis. Major guidelines do not currently recommend vitamin E as a first-line or mainstay treatment for dermatitis, though it may be used as an adjunct in some cases. Overall, while there is some scientific support, the evidence is not robust, and more high-quality, large-scale studies are needed.
