Dermalogica Pro Active Clay Cleanser for Oily Skin is a purifying and deep-cleansing facial cleanser that is specifically formulated for oily and acne-prone skin types. The main active ingredient in the Dermalogica Pro Active Clay Cleanser is Kaolin clay, which is a natural mineral clay that helps to absorb excess oil, unclog pores, and remove impurities from the skin. The clay helps to purify the skin without stripping it of its natural moisture, making it suitable for oily skin types that require balancing. In addition to Kaolin clay, the Pro Active Clay Cleanser also contains a combination of botanical extracts, including menthol and cucumber, which provide a refreshing and cooling effect on the skin. These extracts also help to soothe and calm irritated skin, making it beneficial for those with acne-prone skin. To use the Dermalogica Pro Active Clay Cleanser, you would typically apply a small amount to damp skin and massage it in circular motions, focusing on areas of congestion or excess oil. After rinsing thoroughly with warm water, you can follow up with other skincare products such as toner, serum, and moisturizer.
