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.

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.

Soothing

Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.

Nourishing

Protecting

Traditional Use

A modern synthetic combination of allantoin (derived from comfrey root, traditionally used for wound healing) and vitamin C (ascorbic acid, discovered in the 1930s). This combination was developed to create a more stable, skin-conditioning ingredient with anti-aging potential.
