COSMO TRIAL: Can makeup *really* be sweat-proof?

We put it to the test!

DISCLAIMER: To give your skin a chance to breathe — and keep it in the best shape possible — we recommend that you don't wear foundation to the gym.

Okay, now that we've got that BORING stuff out of the way, let's get real. While wearing makeup during a workout isn't ideal, sometimes, you just want to. We are fallible, human beings, who occasionally like to break the beauty rules.

Let's just say – hypothetically, of course – that you did decide that your workout required makeup, waterproof would be your best bet for sweat-proof coverage.

Here, we put waterproof foundations and mascaras to the test, along with long-wear lipsticks, brow pencils and blush to see if they can stay put during a workout.
