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.
Spots and panda eyes? Not any more.
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.
Waterproof mascaras tend to leave lashes feeling parched and crunchy but Eyeko's clever new formula is filled to bursting with conditioners like vitamin E, ceramide and collagen, so it feels like you're wearing nothing at all. It won't smudge or flake, no matter how fast you go on the treadmill - trust us.
Birchbox's new gym-inspired beauty range is making a case for 'breathable' formulas, free of oil, gluten and parabens, so that you can work out without the worry of breaking out. Use your fingertips to blend this tint onto the apples of your cheeks for a post-spin flush that lasts.
If you find liquid foundation too heavy to work out in but would still like a little coverage, Laura Mercier's Mineral Powder is your best bet. It's oil-free and non-comedogenic (i.e. won't clog pores) so you can sweat it out without the impending fear of an acne cluster.
Like a pair of yoga pants, IT Cosmetics' clever concealer flexes with your skin, so it's less likely to collect in fine lines or end up halfway down your cheeks. Dewy, but definitely not greasy, the added hyaluronic acid gives lacklustre skin an extra hit of hydration. It's one of the hardiest concealers we've tried.
For a contour that's compatible with the cross-trainer, Guerlain's new waterproof bronzer is the one. Despite its unrivalled staying power, it isn't at all heavy or pore clogging. Instead, it feels like satin on the skin and is subtle enough for a no make-up look. We're obsessed.
Forget sweat or saunas, we're pretty sure Wunderbrow could survive a monsoon. Complete with savvy fibres to mimic hairs and specially treated pigments for longer wear, this semi-permanent gel glides through sparse patches without completely soaking your brows in product or clumping up in places. On us, it survived HIIT and a drizzly walk home - genius.
Heavy duty foundation has the tendency to form an occlusive barrier on the skin. Add sweat into the mix and it's not great news for the acne-prone - but that's where Oxygenetix comes in. Formulated with Ceravitae, this medium coverage foundation plies skin cells with oxygen to prevent clogged pores. The SPF 25 makes it a must for those who exercise outdoors.
OK, the pot is pretty tiny but the banana-hued powder inside is mighty. A light dusting over the cheeks, chin and forehead has the muscle to tuck barrecore-induced redness behind a veil, so you can return to the office looking just as flawless as when you left.
La Roche-Posay's dermatologist approved Effaclar Duo [+] moisturiser now comes with a subtle tint to lend sheer coverage while treating any sweat-induced spot eruptions. The thing that swayed us? It leaves skin feeling fresh and matte for hours on end, even if you're susceptible to a megawatt shine.
Don't let the odd-looking brush put you off. We put this waterproof fibre mascara through its paces during a swim and couldn't believe the results - full, fluttery lashes without so much as a single smear. Be sure to invest in a good waterproof eye make-up remover otherwise you'll have difficulty taking it off!
The clue is in the name as to how well Kat Von D's best-selling liquid liner stays around. Whether you're a pilates or burpees kinda gal, you can bet it won't fade to grey or end up on your chin at the end of your workout. Plus, it's probably one of the easiest liquid liners out there to fashion a feline flick with thanks to the ultra-precise nib.
Dermatologist tested, non-comedogenic and free of harsh fragrances, Glossier's Stretch Concealer does exactly what it says on the tin: It shifts with your skin to make cracking and caking a thing of the past, no matter how much you move.
If you're going straight from Psycle to the office and want a low-maintenance look, Nudestix have got you covered. You can contour with it, blend it onto the apples of your cheeks for a believable flush, swipe it over your lids for a dash of colour or dot it on your lips like a tinted balm. Housed in a sleek tin, it won't get lost or collect dirt at the bottom of your gym bag.
