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.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Neutralizes Free Radicals
Traditional Use
A modern synthetic ester combining phytosterols with both linoleic and linolenic acids. Created for cosmetic formulations to provide emollient and skin-conditioning benefits.
