A revolutionary concentrate based on high molecular weight hyaluronic acid, a star ingredient in cutting-edge cosmetics, which produces an immediate tightening and hydrating effect. It protects the skins youthful appearance by preserving the reserves of hyaluronic acid present in the dermis, which diminish with age. From the age of 25, production decreases by up to 70%, and the molecular weight of the hyaluronic acid molecules we generate also decreases. This redensifying and hydrating serum has been specially designed for an immediate tightening effect. To achieve this, it uses high molecular weight hyaluronic acid (150,000 Daltons), which, unlike low and medium molecular weight hyaluronic acid, which only acts on fibroblasts, forms a thin and invisible barrier on the skins surface. This barrier maintains the moisture balance of the dermis, simultaneously attracting moisture from the air, hydrating the skin for increased firmness, flexibility and elasticity, resulting in a more youthful appearance.Directions - Restores vital hydration balance. - Restores lost facial vitality. - Promotes collagen production. - Its smoothing and firming texture makes it an ideal makeup base.INSTRUCTIONS FOR USE For daily care, apply a few drops morning and evening, using light tapping movements, before day and/or night cream.ACTIVE COMPONENTS High molecular weight hyaluronic acid (150,000 daltons) 30%
