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
Lanolin derives from wool grease and has been used as an emollient in skincare since ancient times. Hydrogenated laneth compounds were developed in the 20th century as modified lanolin derivatives designed to function as emulsifiers and conditioning agents with improved stability.
