The Top Acne Causes, and What to Do About Them

Sweat itself doesn't cause breakouts, but it can mix with oils in your pores — and that can lead to acne. Friction can also aggravate acne, so wear loose-fitting clothing made of natural fabrics; synthetic fabrics such as Lycra and nylon can rub against skin, trap sweat, and clog pores. To avoid this, shower as soon as possible post sweat sesh and use a body wash with salicylic acid to keep pores clean.
