Would you like a flawless finish to your foundation. One of the best things after a great moisturizer is Foundation Primer. I never had used foundation primer till about a year ago. I LOVE it! I use one that is silicone based my favorite. I am very oily and I would be worried that one more thing on my face would make it greasy it actually has oil absorbers in it as well so it is fabulous. Primer basically fills in any extra hills and valleys 🙂 makes your skin look more flawless and it also makes sure your makeup lasts longer through out the day. I used to reapply after a portion of the day especially if I was going out. But not anymore. I love people thinking that I reapply all the time! Smash Box photo finish is silicone based it is around $49 it is silicone based. Mary Kay also has a silicone based foundation primer it is only $16 FABULOUS! I don’t put on makeup without it! If you haven’t tried a primer I would. Also Eye primer is something I hardly ever go without. Ladies do you have problem with your eyeshadow creasing? Eye Primer also makes your eye shadow last longer and some of them will make your make up waterproof 🙂 How AWESOME!! If you like to look better longer I would highly suggest you use primers!! One more thing is because eye primer makes it stick and stay you will want to put a teeny bit of concealer (light not drying concealer) over the primer. It will make it easier to blend your eye shadow after the primer. Just a little more info!
