GM Collin Hydramucine Optimal Cream is a hydrating cream with a delicious, ultra-fresh texture and a natural relaxing scent. GM Collin Hydramucine Optimal Cream promotes auto-active hydration by promoting the movement of water from the dermis to the epidermis, increases the capacity of cells to hold water and reduces fluctuation in hydration caused by external factors, and favours the synthesis of hydro-captors to increase the fixation of water in the epidermis.
