Combination, oily and acne-prone skin can appear shiny, coupled with blemishes and dullness. Pores are often enlarged with blackheads and scars. These imperfections are the result of excess sebum and they are very often amplified by an aggressive daily cleansing routine. Act-Biotic is a treatment that helps regulate sebum production and deep cleanse the skin. It controls sebum production and tightens pores, while preventing residual marks. Purified, the skin is clear, supple and radiant with freshness.
