Comedolytic refers to a substance or drug that prevents the development of comedones, which are blemishes caused by oil and skin cells being stuck in the pore. A microcomedone is a subclinical (not yet visible) clogged hair follicle that is microscopically thin. If the number of keratin-forming cells in the skin increases, microcomedones form. This product launch will be brought to you by Eau Thermale Avène.
