Topical Medication: Retinol Acne Treatment

The result of clogged pores is acne - blackheads, whiteheads, pustules, and cysts in the skin. Unfortunately, certain people are genetically predisposed to have more problems with acne than others. At the same time, the natural inflammatory response makes the skin red and irritated, and your pores close up. It gets complicated and messy, very quickly, as this vicious cleanse-and-irritate cycle progresses. Pimples form when hair follicles under your skin clog up. Most pimples form on the face, neck, back, chest and shoulders.
