The Answer: Yes, wearing makeup during your workout can clog your pores and lead to breakouts. As you sweat, your pores open up and allow dirt, oil and bacteria to be excreted. When you’ve got makeup blocking those pores, they can get all clogged up with whatever concealer, foundation or powder you’re wearing plus all that dirt, oil and bacteria. As you can imagine, this leads to nasty breakouts or stubborn blackheads.

If you’re going straight to the gym after work, throw a pack of facial cleansing wipes in your bag. If it’s simple and quick to remove your makeup pre-workout, you’ll be more likely to do it and make it a habit.

If you absolutely have to have something on your face, opt for a tinted sunscreen instead. Most of these formulas are much lighter than other face makeups, and won’t clog pores quite as much. Apply clear spot treatment underneath to any current breakouts you don’t want to get worse. And don’t forget to wash your face completely with a good cleanser after working up a sweat. All that dirt and sweat just festering on your skin is a tried and true enemy of a clear complexion.
