What Causes Acne?

Acne develops on the skin when the pores become clogged, which may occur as a result of an overproduction of oil, a buildup of bacteria or the shedding of dead skin cells. When these substances build up in the hair follicle, they form a soft plug that forces the follicle wall to bulge and protrude from the skin, causing a lesion to develop.

Symptoms of acne can include blackheads, whiteheads, cysts, nodules, pustules, redness and swelling.

What Are Acne Lesions?

Can Picking at or Opening Up Pimples Make Them Better?

Treatment options can include topical creams and ointments, and prescription oral antibiotics. To remove acne scarring, treatments such as dermabrasion or laser therapy may be recommended.
