Acne is a disorder of the hair and oil glands found in the face and upper body. Also known as black heads, whiteheads, spots, pimples or zits.
Science: At puberty androgens (male hormones) increase the production of sebum (oil) from enlarged sebaceous glands that become blocked. Comedones (follicles impacted by dead skin cells and oil) may be open (blackheads) or closed (whiteheads). Inflammation leads to papules, pustules and nodules.
