The Vichy Mineral 89 Booster is a daily treatment designed to hydrate and fortify your skin. Formulated with a high concentration of Volcanic Water and Hyaluronic Acid, this booster acts as a shield against daily aggressors. It is ideal for daily use as the first step in your skincare routine, preparing the skin to better receive subsequent treatments. Regular application helps to visibly plump the skin, leaving it intensely moisturized, strengthened, and luminous.
