The treatment series for balanced, clearer skin in just 7 days. The Hydra Plus Ampoule uses low molecular weight hyaluronic acid and provitamin B5 to support hydration and protect the skin from drying out. This way, the skin is perfectly prepared to absorb the subsequently applied active ingredients. The antibacterial, mattifying active ingredients in the Active Purifier Ampoule, such as tea tree oil, exert their ultimate active ingredient power to provide fast relief for blemished skin. Pimples and blackheads are effectively reduced. Formation of new blemishes is prevented.
