Acne is a common skin condition that causes pimples, blackheads, whiteheads, cysts, or nodules on the skin. It happens when hair follicles get blocked with oil and dead skin cells, leading to the growth of bacteria called P. acnes. Acne usually affects areas with lots of oil glands, such as the face, chest, back, and shoulders. If left untreated, it can cause discomfort, inflammation, and scarring. Treatment options include aesthetic procedures that aim at reducing oil production, unclogging pores, and controlling bacterial growth. With proper management, many people can effectively treat their acne and achieve clearer, healthier-looking skin.
