Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Locks In Moisture
Traditional Use
Developed in the late 20th century as a silicone copolymer designed to improve water resistance and adhesion properties in cosmetic formulations, particularly in long-wear makeup and skincare products.
