Functions
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Anti-Aging
Targets fine lines, wrinkles, or loss of firmness. Works by boosting collagen, speeding cell turnover, or both.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
