PROPERTIES The skin is the largest organ in our body. It is constantly exposed to external factors, and its barrier function is key to protecting our internal organs from the effects of the exposome. Today, we know that 80% of the signs of aging are due to environmental exposure. Therefore, maintaining the skin's natural protection is key. Every day, we are subjected to many aggressions, both external and internal. Our skin has developed a strong and unique strategy to defend itself: the barrier function. A complex structure with many properties (physical, hydric, antimicrobial, antioxidant, and photoprotective). The skin is a complex organ that is capable of defending us against the exposome. We have developed a unique and effective response to strengthen the skin and reinforce its natural defenses against the exposome, reducing its impact on the skin and providing a healthy appearance. Mineral 89 is the immediate-effect fortifying concentrate that strengthens the barrier function, boosts hydration and reduces the adhesion of micro-pollution particles. Formulated with a unique combination of our highest concentration of 89% Vichy Volcanic Water in a minimalist formula with hyaluronic acid. Hyaluronic acid forms a film on the skin's surface to retain internal hydration. Mineral 89 increases corneocyte adhesion and cell adhesion. Vichy Volcanic Water strengthens the skin's antioxidant defenses and rebalances the pH. Ethanol-free and fragrance-free. HOW TO USE Morning or night. PRECAUTIONS AND WARNINGS A formula with only 11 ingredients. Free from fragrance, colorants, silicone, parabens and alcohol*. For the first time, Vichy laboratories have achieved the feat of formulating it in a concentration of 89% Volcanic Water, and associating it with Hyaluronic Acid, a moisturizer of natural origin.
