Acne is an inflammatory skin disorder of the hair follicles and sebaceous glands. They are divided into two groups: non-inflammatory such as whiteheads and blackheads and inflammatory such as papules, postules, nodules, and cysts. Acne can be found on the face, underarms, groin and buttocks, and under the breasts in women. Acne can also arise after shaving or starting a medicine.
