Here's a tip if you're looking for a face primer and don't want to spend a lot of money. Smashbox Cosmetics has a product called Photo Finish that is a primer that you put on after your skin care and before your foundation that is almost exactly the same thing as Monistat Chafing Relief Gel. Smashbox's product is about $35, Monistat is about $7. You can go to Monistat's website and request a sample for free and they'll also send you a $1 coupon! Now, this is not the Monistat that goes down south
It's a chafing relief gel that you would use between your thighs if they rub together, or anywhere you would get chafing. DO NOT use regular Monistat on your face - it's specifically called CHAFING RELIEF GEL.
What a primer basiclly does is even out your skin's surface some so that your foundation goes on more smoothly. It also helps make it last longer.
If you have large pores, the best primer to hide them and make your skin look flawless is Clinique's Instant Pore Perfector. It's about $17 and you only use a little bit, so the tube lasts a very long time.
Good luck!! Hope this helped
