Bacne
Bacne is pimples that appear in teenagers or adults on the dorsal region of the body, which is quite oily. Because of its oil, when the pores clog, the sebaceous glands cannot eliminate the oil, which causes acne to appear.
Unlike pimples that appear on the face (caused by the action of bacteria that lead to skin inflammation), bacne is related to the mechanical obstruction of the pores located in the back.
Sweating, for example, is one of those mechanical factors that can be responsible for the appearance of acne on the back. As well as wearing clothes that cannot adequately absorb perspiration.
The therapy used for bacne is the same as that indicated for the face but in slightly stronger concentrations. This is because, generally, the skin on the back is less likely to develop irritations.
