39
A hybrid molecule formed by esterification of ascorbic acid (vitamin C) with the carboxyl groups of hyaluronic acid via a propyl linker. Combines the antioxidant/brightening properties of ascorbic acid with the humectant properties of hyaluronic acid. The ester bond provides improved stability versus free L-ascorbic acid while still hydrolyzing to release the active forms. Used in multi-functional serums for combined brightening, antioxidant, and hydration benefits.
40
A cationic quaternary-ammonium derivative of hyaluronic acid that binds electrostatically to negatively charged skin proteins, delivering sustained surface hydration.
