Dermosthetique Serum Hydratant by La Biosthetique is a cell active anti ageing hydration serum with a long lasting effect. Dermosthetique Serum Hydratant intensively gives moisture and a binding effect to all layer of the epidermis. Hyaluronic acid is a natural component of our connective tissue that has an instant, long term effect on the skin's moisture binding capacities. Short chain hyaluronic acid rapidly penetrates the skin and stimulates the skin's renewal process. It improves cellular cohesion in the stratum corneum, binds moisture and also acts as a carrier for the active ingredients, enabling them to be better absorbed by the skin. Clincal studies prove that after using Dermosthetique Serum Hydratant daily, the cycle of the cell division and thus skin renewal is increased by 40% within 11 days compared to that of untreated skin.
