Acne is a skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It causes whiteheads, blackheads, or pimples. Acne is most common in teenagers, although it affects people of all ages. There are effective treatments for acne, but acne can be stubborn. Pimples and bumps heal slowly, and as one begins to go away, others seem to pop up.
