Vichy Mineral 89 Boost moisturizing cream 72H Rich Dry skin 50ml Every day the skin is exposed to external aggressions: the skin barrier weakens and the daily losses of water, minerals and hyaluronic acid increase. It is therefore essential to provide the skin with all the elements it needs. Mineral Day Cream 89 is your daily dose of minerals, pure hyaluronic acid, vitamins and squalane for fortifying, long-lasting hydration. Its melting and non-greasy texture offers all the comfort that dry skin needs. 72 hours of reinforced hydration.
