BIODERMA Hydrabio H2O Micelle Solution is the 1st & only dermatological micellar water perfectly compatible with the skin. Its fatty acid esters, the constituent elements of micelles, are similar to the phospholipids of the skin cell membranes & naturally help rebuild the skin's hydrolipidic film. Thus, Hydrabio H2O guarantees unrivalled tolerance & comfort for optimum make-up removing efficacy. Moreover, its Aquagenium® exclusive biological patent retrains the skin to activate its natural moisturising capacities by stimulating the production of aquaporins, water channels in the skin, & retain the water it needs to be balanced.
