The question arises due to it being the new year and so many people resolve to start exercising again. For many, the only time to get to the gym is right after work, since it's the only time available. Once at the gym, some take their makeup while others don't and those that don't are not making a great choice.
When you work out, you tend to sweat. When you exercise, your temperature increases, you sweat, and your pores tend to open allowing particles of makeup to block them. This can lead to breakouts and an uneven skin texture.
Furthermore, when you exercise, you usually have constant contact with the floor, with equipment such as yoga mats, bicycles, weights, and machines which are great places for bacteria to breed. This type of bacteria is most likely to cause acne. The make up you wear gives the bacteria something to hold on to. Since we touch our faces 3.6 times an hour on average, it is easy to transfer the bacteria from the equipment to your face.
Fortunately, there is no evidence that wearing makeup while exercising can lead to long term damage, there can be long term damage is you exercise outside regularly without wearing a good sunscreen that is rated at least SPF 30. Furthermore, do not rely on a foundation with sunscreen because it tends to slip when you begin to perspire and the SPF is not always that high. Layer the foundation, concealer, or mineral makeup over the sunscreen. It is recommended people use a mineral rather than chemical sunscreen but if you have to use a chemical one, choose a gel like formulation.
If you still want to were makeup while working out because you feel better, you need to follow a few steps to do it properly. If you have oily skin, you should clean your face with an oil free cleaner to get rid of any bacteria present so they don't get into your open pores. If on the other hand, you have sensitive skin that reacts when you sweat, consider putting on a layer of light moisturizer to protect it.
Rather than using an oil based foundation because it is more likely to clog pores, consider using either a water based foundation or mineral makeup to decrease the chance of clogged pores. You do not want to do anything to clog pores because it could lead to acne and blackheads. In addition, if you use concealer, choose a highly pigmented one that is in your skin tone, only on areas with discoloration, spots, redness, or dark circles and blend it all in. Although concealer is usually water resistant, make sure it is.
On the other hand, if you have skin that is prone to breakouts or sensitive skin, you might consider using mineral makeup since it is breathable. You want a shade that is the same as your skin tone but doesn't have shimmer or sparkle. Furthermore, when you wear makeup at the gym, you want to highlight your lips and brows. If you want your brows to look great the whole time, finish with a bit brow wax after filling in the thin spots and getting it just right.
As for lips, do not go for an explosion of color. Settle for a more subtle color wash. Choose a lipstick designed to be water resistant and is long wearing. When you apply it, dab it on and then pat the extra off and do not use a lip liner or gloss because hair can get stuck on your glossed lips.
Should you want to use eye shadows to create a look, choose water resistant products so they don't run into your eyes once you start sweating. Apply the shadow, add a bit of eyeliner and finish with water resistant mascara for that look.
Once you've finished working out, wash your face again to get rid of dirt, bacteria, or excess makeup. Finish with a light moisturizer to keep the skin from becoming too sensitive. Let me know what you think, I'd love to hear. Have a great day.
