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.

Reduces Inflammation

Brightens Skin

Fights free radical damage

Traditional Use

First isolated in 1951 as a mitochondrial cofactor in cellular metabolism. Its antioxidant properties in skincare were discovered in the 1990s when researchers recognized its ability to regenerate other antioxidants and reduce oxidative damage.
