What is Primmer?

A primer is what you use to prime your face before you put on a foundation. It's supposed to make your makeup last longer. Some primers claim to hide your pores. Some claim to even out your skin tone. Which one is the best? It depends on what you want and your skin type. Smashbox: Photo Finish is very popular. It helps to hide pores and makes your skin smooth but it tends to make your skin oily. Comes in various formulas. Benefit: That Gal is not bad, smells nice too. It claims to have this stuff to reflect light so your skin appears smooth and even toned. MAC has Prep+Prime Skin Protect. This one has a sun screen and helps control oil too.
