Moisture Regulating Serum acts on 2 regulation mechanisms of skin hydration through an active ingredient derived from wild pansies (viola tricolor). On a basis of a 4% concentration in the serum, this active ingredient increases the synthesis of hyaluronic acid thus facilitating the epidermal water retention. It also stimulates the synthesis of aquaporines-3, genuine water channels inserted in the epidermal cell membranes and enabling irrigation of the epidermis. Therefore, the natural hydration  processes are activated in order to constantly achieve a balanced water level into the skin.
