Acne is a skin condition that occurs when your hair follicles become filled with oil and dead skin cells. It often causes blackheads, whiteheads or pimples, and normally appears on the face, forehead, chest, upper back and shoulders.
Acne is most common in teenagers and young adults. Symptoms range from uninflamed blackheads to pus-filled pimples or large, red, and tender bumps.
Treatments for acne include over-the-counter creams and cleanser, as well as prescription antibiotics.
