Blackhead

Blackheads are acne that appear as small, dark spots on the skin, usually on the face, neck, or back. They are caused by the buildup of oil, dead skin cells, and bacteria in the hair follicles. Blackheads can be treated with over-the-counter topical medications, such as benzoyl peroxide or salicylic acid, or prescription medications, such as retinoids or antibiotics. Professional treatments like chemical peels or microdermabrasion may be recommended in some cases. Prevention involves good skincare habits, including regular cleansing and exfoliation.
