Illustration of how an acne spot is formed. The sebaceous gland produces sebum which travels up the hair and exits via the pore. The sebum protects the skin and gives it its shiny appearance in the case of greasy skin. When sebum is produced in too large a quantity, the pore is blocked which forms a comedo (black or white head) where the follicle enters the skin. The accumulation of sebum can turn into swollen lesions and produce a spot (pustule or white head).
