Back acne – commonly known as “ Bacne “.
Like acne and pimples on the face, they are due to bacterial infection of hair follicles of the back.
They are pretty common and in face, may affect more than half of people with acne. 
Back acne is due to the accumulation of oil and keratin within the pores of the skin, combined with an overgrowth of bacteria, which triggers an inflammatory response.
Increased sweating and friction from clothes and athletic gear can also be a contributing factor for back and shoulder acnes
