Acne is a long-term skin disease that normally occurs when hair follicles are clogged with dead skins cells and oil from the skin. They can generally be characterized by blackheads or whiteheads, pimples, oily skin, and possible scarring. Acne primarily affects areas of the skin that have a high number of oil glands. Usually on the face, upper part of the chest, and the back.
Acne’s severity can be classified as mild, moderate, or severe, which helps to determine the right treatment for each case. Common features of acne include increased secretion of oily sebum by the skin, microcomedones, comedones, papule, nodules (large papule), pustules, and scarring.
