One of the main causes of acne on your back and chest is from working out. Tight gym clothes trap sweat and oil close to the skin, which can clog pores and hair follicles and cause back acne breakouts. Change out of your sweaty gym clothes as soon as possible and hit the shower. Use a body wash with benzoyl peroxide or salicylic acid to reduce breakouts and kill bacteria.
While your facial skin may dry out quickly, especially after showering, other parts of your body don’t require the same amount of moisturizer. Angela Lamb, MD, a dermatologist with Mount Sinai Hospital in New York City, recommends applying moisturizer to your legs and arms, but using a lighter touch on your chest and back. These areas have more oil glands than your extremities, and may not need any extra moisturizer.
