Why Do We Have Blackheads

Blackheads are black specks that appear on the face, shoulders, upper arms and chest. They occur when hair follicles or sebaceous glands of the skin become blocked with the skin's natural, oily secretions or with some oily chemicals or cosmetic ingredients. The mixture trapped inside the follicle hardens and becomes a olug that blackens on the surface where it meets the air. The incidence of blackheads can be reduced by regular washing and by avoiding comedogenic chemicals.

There is rarely a bacteria infection in blackheads but, if they do become infected, red pimples appear. Whiteheads and acne occur when the infection has developed.
