Acneic skin disorders occur as the result of excessive sebum or oil production that mix with keratonized dead skin cells inside the hair follicle. This creates a micro plug or comedone. There are a variety of lesions that appear as blackheads, pimples, pustutles, papules, cysts, and nodules. They can appear on the face, chest, and back. There is a classification for lesions that helps us discern the severity of acneic skin conditions presented by Dr. Kligman. He gives us the grades of acne 1- 4.
