Skin Eternal’s five key ingredients support healthy skin tissue and protect the skin. In Vitro research suggests that Ascorbyl palmitate, a fat-soluble vitamin C ester, may be more beneficial in providing the protection of antioxidants to the lipids in the skin’s cell membranes than water-soluble C. DMAE is a predecessor of choline, a vital part of skin cell membranes. Alpha-lipoic acid is a potent water- and fat-soluble antioxidant that reuses the antioxidant vitamins E and C. Grape seed extract assimilates water-soluble and lipid free radicals, and upholds the participation of collagen and elastin.
