Hydradermie is an exclusive Guinot treatment that uses galvanic rollers to penetrate ionised hydrating gels deeper into the skin. Mild electrotherapy and the gentle massaging movement of the rollers helps the active ingredients penetrate the deep layers of the skin, using high frequency action to oxygenate and energise the cells. In little over an hour, your skin looks and feels more moisturised and radiant and your face, remarkably rested.
