Vitamin E, including its gamma tocopherol form, has some scientific basis for use in supporting or treating dermatitis, but the evidence is limited and not robust. Vitamin E is well known for its antioxidant and anti-inflammatory properties, both of which are relevant to skin health. Some studies have shown that topical or oral vitamin E may improve symptoms of atopic dermatitis (a common form of eczema), reduce skin inflammation, and help in the healing process by protecting cell membranes from oxidative damage. For example, a few small clinical trials have found that oral vitamin E supplementation can reduce the severity of atopic dermatitis symptoms and decrease itching. There is also evidence supporting the use of topical vitamin E in improving skin barrier function and reducing irritation.

However, most of the research does not distinguish between different forms of vitamin E, and alpha-tocopherol is far more commonly studied than gamma-tocopherol. Gamma tocopherol is less prevalent in supplements and dermatological preparations, and its specific effects in dermatitis are not as well documented. Current clinical guidelines do not universally recommend vitamin E as a primary treatment for dermatitis due to inconsistent results and a lack of large, high-quality studies. In summary, while there is some scientific support for the use of vitamin E in dermatitis, particularly in its alpha form, the evidence is limited and should be considered supplementary rather than primary treatment.
