Skin Eternal contains five key ingredients that together protect the skin and support healthy skin tissue. Ascorbyl palmitate is a fat-soluble vitamin C ester, which may be more effective than water-soluble C in providing antioxidant protection to the lipids in cell membranes, according to in-vitro research. DMAE is an immediate precursor of choline, an important component of skin cell membranes. Alpha-lipoic acid is a powerful fat- and water-soluble antioxidant that recycles the antioxidant vitamins C and E. Grape seed extract scavenges lipid and water-soluble free radicals, and supports the integrity of elastin and collagen.
