Its exfoliating action, derived from the combination of 3 forms of AHA, is progressive to ensure better skin tolerance. Zinc gluconate, a sebum regulator and purifier, regulates sebum production and limits the proliferation of imperfection-causing micro-organisms. Thanks to its mattifying agent, it absorbs any excess sebum, thus reducing the shiny appearance of oily skin throughout the day. It leaves the skin clear and non-shiny. How to use: Morning and/or evening.
