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.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks in moisture
Neutralizes free radicals
Traditional Use
A naturally occurring phospholipid found in cell membranes with limited traditional use. Used in modern skincare formulations as a hydrating and skin-conditioning agent.
