Croix Blanc Bipolar Aqua Gel 100ml (Set of 2) For pure, newborn-like skin free of blemishes, dullness, and wrinkles. Croix Blanc Bipolar Aqua Gel contains bipolar (dual-polarity) ions to reactivate skin cells. These are positive (+) cluster ions and negative (-) ions that coexist without mutual annihilation. This possibility overturns past common sense, awakening skin cells from dormancy and leading to a return to pure skin. Croix Blanc Aqua Gel has a secret, effective way to use it. One of the characteristics of bipolar ions is their high permeability.
