According to dermatologists, wearing the wrong type of make-up during a workout has the potential to cause acne and uneven skin texture - not cool.
But make-up is currently evolving to meet the needs of every gym bunny out there, with brands like Clinique and Eyeko hatching clever new product lines complete with skin-friendly formulas (aka non-comedogenic, mineral, breathable) and pigments that'll stay put through more or less everything, from Bikram Yoga to Spin.
So if just the thought of forgoing the foundation is enough to break you out in a sweat, check out our pick of the make-up products that you can exercise in, no problem.

If there's one thing we know about exercising, it's that we sweat. Which is where Sport FX's genius spray comes in. Spritz on skin before applying make-up to make it last through even the most intense work out sessions, or spray after your work out and let the the menthol cool and refresh a flushed face.

There's one thing all dermatologists agree on: that if you exercise outside, a high factor sunscreen is a must, no matter what the weather. Clinique's new workout-friendly foundation boasts a brilliant SPF 40 but it's far from ashy or prone to slipping. Completely oil-free, the pigment particles really cling to the skin, lending impressive coverage and a satisfying matte finish. See ya, shiny t-zone.
