Neck acne is caused by a variety of factors, including skin type, comedogenic products, skin irritation, poor hygiene, fluctuations in hormones, stress, and environmental triggers. The neck contains pores and oil glands in a high concentration, which can become irritated from excess oil, dead skin cells, and bacteria, leading to clogged pores. Hormonal imbalances, not washing the neck regularly, makeup, sunscreens, hair products, certain body washes, and friction from clothing or accessories can also cause neck acne. Treatment for neck acne is similar to facial acne, but caution and a gentle approach need to be taken when using skincare on the neck since the skin is thinner on the neck than on the face. If over-the-counter solutions are unsuccessful, consider speaking with a doctor about more aggressive treatment options
