Fortunately, there are things you can do to keep your makeup from being sweated off. If you take a shower in the morning before getting ready for the day, do not start your makeup immediately after stepping out. Give your body about 10 minutes so it has a chance to cool down otherwise your skin can absorb the makeup and you might break out later on and your face won't look as polished when you are done.
When you start doing your makeup be sure you've applied a primer to your face because the primer places a barrier between your skin and your make up. A primer also helps the makeup stick to your face better. In addition, powder the makeup when you are done or apply a spray to set the makeup so it doesn't dissolve when you sweat. If you use a setting spray, choose one that does not contain alcohol because alcohol can cause the makeup to dry out and crack. If you want to make sure your makeup stays, lightly powder it with a translucent powder before using a setting spray.
Although the primer will help any foundation last, it is best to use a powder or a slightly tinted moisturizer with an SPF of 30 or higher. I've used slightly tinted moisturizers before and I love them because I get a bit of color and the sunscreen has helped me keep from getting burned. In addition, the slightly tinted moisturizer is less likely to run since it is lighter than a regular foundation.
If you do start sweating, immediately pull out a paper towel and blot your makeup before you apply the powder. If you apply the powder without blotting the sweat, then your makeup begins to look caked since the powder is sitting on top of the moisture. It is easy to take a few paper towels, cut them into smaller pieces and stash them in your purse where they are easily reachable. If you don't want to use paper towels, invest in proper blotting paper which is actually designed to absorb sweat or oil.
In addition, keep a small makeup brush in your purse to use when you want to reapply powder. Another thing is to keep a few Q-tips in there so you can remove any bits of makeup that end up on your face in the wrong place. Q-tips are great for tidying up and take very little space.
On the other hand, if you want a full face from primer to foundation, to everything then try this. Apply a liquid foundation followed by a powder on top to set it. When you do blush, start with a creme blush and finish it with a powder flush. When you do your eyes, fix the eye brows first before applying the eye shadow. For your eye lashes, select a waterproof mascara so it stays better. When these items are applied in this order, it creates a face that won't melt in the hot weather.
No matter which way you choose to go, keep a light floral spray in your purse so you can spritz your face with it to cool yourself off. Remember that less is more in the summer. Let me know what you think, I'd love to hear. Have a great day.
