Moreover, it was observed that vitamin E, as a physiological component of cellular membranes, is responsible for their stability and proper level of fibroblasts moisture. Tocopherols are used in cosmetic preparations for dehydrated and damaged skin. Preparations with vitamin E moisten and grease the skin and it becomes smoother and better-toned. It is mainly connected with vitamin E antioxidative abilities although it is not the only aspect of its activity. On the basis of numerous studies, both in vivo and in vitro, it has been revealed that vitamin E plays an important role in regulation of many cellular functions on DNA level, by the influence on gene expression.
