Acne - Symptoms and Treatment

Acne vulgaris (or simply acne) is a common human skin disease, characterized by areas of skin

with seborrhea (scaly red skin), comedones(blackheads and whiteheads), papules (pinheads), nodules (large papules), pimples, and possibly scarring.^[1] Acne affects mostly skin with the densest population of sebaceous follicles; these areas include the face, the upper part of the chest, and the back.^[2] Severe acne is inflammatory, but acne can also manifest in noninflammatory forms.^[3] The lesions are caused by changes in pilosebaceous units, skin structures consisting of a hair follicle and its associated sebaceous gland, changes that require androgen stimulation.
