What Causes Zits?
Acne is a disease of the pilosebaceous models, also referred to as PSUs. PSUs are located in nearly all locations of the body. They include a gland that is related to a canal that is referred to as a follicle; the follicle comprises a fine hair. The largest number of PSUs are situated on the face, upper back and chest. Sebum, an oily substance secreted through the glands, finds its way to the floor of the pores and skin by the skin pores or the opening of the follicles.
