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

A synthetic ester created in the late 20th century. Used in cosmetics as an emollient and film-forming agent that provides conditioning and wear-resistance to formulations.
