Science & Benefits

A cellulose-derived cationic polymer. It functions as both a film-former and a conditioning agent. By forming a protective, non-occlusive veil over the stratum corneum, it traps water-soluble humectants against the skin. It is zero-comedogenic and zero-irritant. In acne-safe mists and toners, it ensures that the hydration remains on the skin for hours rather than evaporating immediately, providing sustained comfort to skin irritated by active treatments.
