Blackheads: Comedones: Skin Impurity

Blackheads, or comedones, are a type of skin impurity. They are blockages caused by the keratinization of sebaceous gland follicles. These culprits are often found on the nose, particularly the nostrils, and the chin. They are easily recognized by their dark, pigment-like shape and color.

Blackheads occur particularly frequently during puberty in adolescents but can also reappear throughout life in a milder form. Blackheads, along with pimples, are a typical symptom of acne.
