Acne occurs when hair follicles become clogged.

Acne forms when hair follicles clog, often due to genetics, certain conditions, or medications. Chin-line acne can be treated with over-the-counter products, though severe cases may require a doctor’s prescription. Improvement may take weeks, depending on treatment and severity. This article details causes, risk factors, treatments, and when to seek medical advice.

What causes acne along the chin line?
Sebaceous glands produce oils to lubricate skin, exiting through hair follicle pores. Excess dirt, hair, and dead skin cells can block these pores. Bacteria on the skin’s surface may multiply in clogged pores, triggering inflammation that leads to pimples or blackheads.
