This product contains four types of hyaluronic acid molecules, providing intensive multi-level hydration. The hyaluronic acid used in the formula is a special combination of four different molecular weights: 1. high molecular weight: forms a protective film on the skin surface, reducing skin moisture loss; 2. medium molecular weight: retains moisture on the skin surface, nourishing the top (horny) layer of the skin; 3. low molecular weight: closely adheres to the horny layer, providing excellent hydration and restoration; 4. ultra-low molecular weight: quickly penetrates deep into the skin, hydrating and restoring it from the inside. Hyaluronic acid is perfectly combined with polyglutamic acid: this active substance has the ability to retain moisture, while preventing the degradation of hyaluronic acid, which is naturally contained in the skin. The product is also enriched with inulin, a natural prebiotic that helps maintain the skin's microbiome and allows the epidermal barrier to function properly.
