What It Does

A fat soluble antioxidant that protects cell membranes from free radical damage. Works synergistically with vitamin C.

Vitamin E, specifically tocopherol and tocotrienol, is a fat-soluble antioxidant that protects cell membranes from oxidative damage. It is one of the most important antioxidants in the body and is naturally present in skin. Topically applied vitamin E provides additional antioxidant protection, moisturization, and supports wound healing.

Vitamin E works synergistically with vitamin C, with each regenerating the other after neutralizing free radicals. This partnership makes vitamin E particularly effective when combined with other antioxidants. Vitamin E also has emollient properties, improving skin texture and reducing moisture loss.

Japanese skincare incorporates vitamin E across all product categories, from serums to sunscreens to cleansing oils. It is often combined with other antioxidants like vitamin C, astaxanthin, or green tea for enhanced protection. DHC is particularly known for vitamin E-rich formulations.
