While makeup can act as extra protection from UV rays, it all comes down to the formula. After all, makeup is made out of chemicals that when exposed to the sun, may break down and have negative reactions on your skin. Additionally, foundation may prevent sweat from leaving your skin which will, in turn, clog your pores with debris (via Good Looking Tan).

In order to take care of your skin when tanning, avoid exposing yourself to the sun when it's at its strongest, which is between 10 a.m. and 4 p.m. (as per Healthline). According to Tanning Girl, if you're getting a spray tan, it's not advisable to wear makeup either. This is because makeup will stop the spray tan from reaching your skin, causing an uneven finish.

Further, using liquid makeup right after getting a spray tan is also not advisable as the makeup's chemicals will clash with the spray tan's chemicals, leaving patches on your new tan. Tanning Girl also notes that when it comes to spray tans, it takes time for a tan to set, and during this time, you won't be able to wash your face. And so, with that in mind, any makeup that requires you to wash your face will not work, at least not until enough time has passed (6-8 hours).

Happy tanning!
