Is Hydroxypropyltrimonium Hyaluronate a Good Ingredient?

Rated Great because this quaternized HA shows strong substantivity and water-binding, and supplier data along with small studies point to improved moisturization and conditioning compared with standard HA. It's generally low-irritating and stays effective at modest use levels without stickiness, which sets it apart from ordinary HA derivatives.
