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.

Soothing

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

Hair Dyeing

Locks In Moisture

Brightens Skin

Colors Hair

Traditional Use

Isolated from plant sources in the 19th century and used traditionally in European herbalism for skin conditions and inflammatory responses. Later synthesized for use in modern skincare as an antioxidant and skin-soothing agent.
