Deriva Cms Gel 15 gm is a member of the group of acne-treating dermatological products known as "antiacne" (pimples). Acne is a common skin ailment that develops when oil and dead skin cells clog hair follicles. The bacterium that causes acne feeds on sebum, the natural oil generated by skin, producing inflammation and redness. Adapalene (man-made vitamin A) and Clindamycin are the two medications included in Deriva Cms Gel 15 gm (antibiotic). Adapalene (man-made vitamin A) works by loosening the skin's surface cells and unclogging pores by lowering the amount of oil produced by the skin. This decreases the development of whiteheads, blackheads, and pimples on the skin's surface.Disclaimer:For more information contact your physician.
