Acne is a common skin condition that happens when pores become clogged with oil, dead skin cells, bacteria, and inflammation.
Types of acne spots
Acne can cause blackheads, whiteheads, pimples, pustules, nodules, or cysts. It often appears on the face, chest, back, and shoulders.
Why acne happens
Hormones, genetics, skin oil, bacteria, certain products, stress, and some medicines can contribute. Acne is not simply caused by being dirty.
Severe acne or acne that scars should be discussed with a clinician or dermatologist.
