The antibacterial and mattifying active ingredients in the Active Purifier ampoule, such as tea tree oil, offer maximum active ingredient power to help blemished skin quickly. Pimples and blackheads are effectively reduced. The formation of new impurities is prevented. Result: clear, purified and matte skin. Application: After cleansing with Babor Cleansing products. Shake the ampoule and cover the neck of the ampoule with a cosmetic tissue or the ampoule opener provided. Hold the ampoule by the neck or opening and break open the coloured bottom ring with a jerky movement. Pour the concentrate into the palm of your hand and apply to the face, neck and décolleté. Gently dab onto the skin. Then apply a moisturising cream with sunscreen.
