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.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.

Traditional Use
Used in traditional Chinese and Native American medicine for reproductive and menopausal health. European herbalists adopted wild yam in the 19th century for hormonal balance, though topical cosmetic use is more recent.
