Blackheads are easily recognizable as small, dark spots on the skin’s surface. They are typically painless and do not cause inflammation unless they become infected or irritated. Blackheads are most commonly found on the face, particularly on the nose, forehead, and chin, but can also appear on the back, chest, and shoulders.
Diagnosis is usually straightforward and involves a visual examination by a dermatologist. In some cases, magnification tools may be used to closely inspect the skin and confirm the presence of blackheads. Early diagnosis and treatment can prevent the development of more severe acne.
