Blackheads, also called blackheads, occur when skin pores are clogged with excess sebum and dead skin cells, preventing them from closing. We find Blackheads mainly in areas where the sebaceous glands, which produce sebum, are located. In people with mixed skin, blackheads often appear in the famous T-zone of the face that includes the forehead, nose, and chin. Blackheads can also appear on the chest, back, and shoulders.;sid=47f41375ce8d6724c9bb58ca4848fc8e
