Hyaluronic acid

What is Hyaluronic acid?

A humectant that binds water in the upper skin layers, appearing on INCI as hyaluronic acid or sodium hyaluronate. Formulas often blend several molecular weights for different depths of hydration — a genuine formulation choice, though it is also one of the most over-claimed points on a K-beauty spec sheet.
