Acne vulgaris is a common skin problem that happens when pores become blocked by oil, dead skin, and bacteria. It can cause pimples, blackheads, whiteheads, and sometimes painful bumps on the face, chest, shoulders, and back.

Acne is most common in teenagers because of hormone changes, but adults can also get it. Stress, oily skin products, and family history may make acne worse.

Treatment includes washing the skin gently, using medicated creams or tablets, and keeping a healthy skin-care routine. Treating acne early can help prevent scars and improve self-confidence.
