About





            

                
Vitamin E is the major lipid-soluble antioxidant in human skin, concentrated in the stratum corneum. It accumulates in cell membranes and protects polyunsaturated fatty acids from lipid peroxidation. Research suggests vitamin E works synergistically with vitamin C for photoprotection, and combined oral supplementation is associated with reduced sunburn response (higher MED).

            

        

        

        
        
        

            

  
How It Works





            

                
Fat-soluble antioxidant that accumulates in cell membranes and protects polyunsaturated fatty acids from lipid peroxidation; supports skin barrier function by maintaining stratum corneum lipid integrity; works synergistically with vitamin C to regenerate oxidized tocopherols.
