Fundamental Hydration Serum + Extraits Tissulaires serum is an instant moisturizer with anti-dehydration properties. Its formula is designed to continuously capture and diffuse water to restore the skin’s water balance. The combined action of its active ingredients helps kickstart the skin’s internal hydration mechanisms, slow down imperceptible water loss, and strengthen the hydrolipidic barrier so natural hydration mechanisms are restored. Skin quality is visibly improved. The skin is moisturized, regulated, and protected from harsh environmental stressors. The Science: Water is the human body’s main component, which makes moisturizing one of the primary needs for the body and therefore the skin. It therefore plays a major role in the skin: it protects the epidermis (barrier function) while giving the skin elasticity and suppleness.
