Glycerin

Glycerin, also called glycerine or glycerol, is one of the most widely used humectants in skincare. It attracts and holds water in the outer layers of the skin, which helps improve softness, flexibility and day-to-day hydration.

Because glycerin appears in a very large share of cosmetic formulas, Luxiface treats it as a foundational supporting ingredient rather than a formula-defining active. Its presence still matters, but it usually tells you less about a product's unique purpose than ingredients such as retinoids, ceramides or tranexamic acid.
