Functions
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.
Soothes Skin
Traditional Use
Discovered in the early 20th century when Hungarian scientist Albert Szent-Gyorgyi identified them in citrus fruits. Historically consumed through plant foods; incorporated into skincare in the 1980s-1990s as research confirmed antioxidant and anti-inflammatory benefits.
