Body acne develops in a similar way to facial acne. However, the skin on the body can be thicker than that on the face and often has larger pores, making for more severe acne at times.

Similar to traditional acne, back (Bacne) and chest acne can also be caused by stress and hormones. Back and chest acne can also occur due to the clothing that we wear and our daily activities. Perspiration and tight fitting clothing are factors that can explain why many physically active men and women are prone to back (Bacne) and chest acne. Synthetic materials such as Lycra and Polyester trap in perspiration which then mixes with surface oils. This results in clogged pores and may cause whiteheads and pimples.
