Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Locks In Moisture
Traditional Use
A highly lipophilic vitamin C ester developed for improved stability and penetration in oil-based cosmetics, designed to overcome the oxidation issues of unmodified vitamin C.
