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.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks in moisture
Traditional Use
A phospholipid component of cell membranes found naturally in eggs, soy, and other plant sources; used historically in traditional medicine for skin health. Modern cosmetics use it as a conditioning agent and delivery system for other skincare actives.
