Functions
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Neutralizes Free Radicals
Traditional Use
Developed in the mid-20th century as a fat-soluble derivative of vitamin C to improve stability and skin penetration compared to L-ascorbic acid, addressing the instability issues of native vitamin C in skincare.
