The Advanced G?nifique Hydrogel Melting Mask responds to skinƒ??s temperature and the gel essence gradually melts, releasing hydration and active ingredients such as bifidus extract into the skin. Bifidus was selected for its ability to improve of the structure and defence of the skin's epidermis. The mask contains the same quantity of bifidus extract as one full 30ml bottle of Advanced G?nifique.
