Blackheads are a form of acne and can form anywhere on the skin. Unlike other acne, such as cysts, blackheads are not caused by bacteria. They are caused by a combination of sebum, dead skin cells and impurities that clog pores and create a strong substance. The upper part of the pores is in contact with the air and the material oxidizes and takes on a dark color.

Blackheads are found mainly in the T-zone of the face (chin, nose and forehead), but can form anywhere on the body. The ears are particularly predisposed as they are not treated like the rest of the skin.

To prevent them, it is enough to wash your ears regularly and remove the layer of dead cells once a week with a scrub. If this method is not effective, you can clean the blackheads with the help of a special metal tool. Be sure to clean the area and tool before and after.
