Boi Thermal Black Mud Mask has been created to remove all traces of shine, impurities and imperfections from the face. Ideal for all skin types, including combination and oily skin. Its components help the skin to detoxify itself, thus favouring the reduction of toxins and dirt that the skin accumulates in the short and medium term. Each of the components has a specific function in improving the appearance of the face. The absorbent action is carried out by the active carbon, while the Mantha Piperita L extract works as an antioxidant. The Font del Boix Water soothes and moisturises thanks to its hypotonic properties. These benefits are due to the fact that the external part of its cells concentrate the least amount of solute compared to the internal part.
