Extended data:

Blackhead, also known as blackhead acne, is an open acne (the surface layer of sebum blocking pores is directly exposed and in contact with air and dust in the air). It is caused by the oxidation of skin oil in the air, which stinks and turns black. Blackhead acne is common in adolescents, and it occurs on the face, chest and back, especially on the nose. It is characterized by the obvious enlargement of pores and the appearance of black spots, which are worm-like after extrusion and black at the top. With blackheads, pores naturally become bulky.
