Understanding Back Acne (Bacne)

Back acne, commonly referred to as 'bacne,' occurs when the hair follicles on the skin become blocked by a combination of dead skin cells, sweat, and dirt, which mixes with sebum—an oily substance produced by the glands in your skin. Acne can appear in various areas, including the back. While bacne is frequently observed in male teenagers, it is a condition that can affect individuals of any age and gender.
