Using a toner is a key step between cleansing and hydration. This product completes the cleansing of the skin and thoroughly preps skin for other treatments. Formulated with 5% Gluconolactone, a particular type of exfoliator that belongs to the category of poly-hydroxy acids (PHAs). They have larger molecules than alpha-hydroxy acids. Therefore, they act on the most superficial layers of the epidermis with mildly irritating action and are suitable for sensitive skin. The action of PHAs facilitates the absorption of other active ingredients applied shortly after. Enriched with Regenine, a mix of fruit acids, and natural propanediol. Perfectly suitable as a maintenance product to be used at home after professional exfoliating treatments.
