Getting hot and heavy in an outfit that’s too tight can cause sweat and bacteria to become trapped inside your clothes. This irritates your skin and causes your body to break out. “Your sweat creates a warm, damp environment where acne bacteria can thrive,” says Schlessinger.
The fix: “The best way to prevent body acne is to shower immediately after you work out if you think your clothing is hugging too tightly,” says Schlessinger. He recommends using a benzoyl peroxide body wash like PanOxyl Acne Foaming Wash 105 Benzoyl Peroxide ($12, lovelyskin.com). “Benzoyl peroxide works gently to remove excess oil, bacteria, dirt, and other impurities,” he says.
No shower at your facility? Change into fresh clothes and shower as soon as you get home. You can also try wearing looser, more breathable fabrics to minimize the amount of trapped sweat. If you do notice breakouts on your back or chest, target trouble spots with a salicylic acid treatment like Glytone Acne Treatment Spray, ($40, dermstore.com). “It has a 360-degree spray nozzle that allows for easy application from any angle—perfect for those hard-to-reach areas like the back,” says Schlessinger.
