Functions
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Bleaching
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Skin Protecting
Helps rebuild and strengthen your skin barrier — the invisible shield that keeps moisture in and irritants out. Essential after over-exfoliating or harsh weather.
Nourishes & Protects
Traditional Use
Developed as a fat-soluble vitamin C derivative that combines ascorbic acid with linoleic acid (an essential fatty acid) to provide both antioxidant and skin barrier support in modern skincare.
