I was looking for a replacement/dupe primer since they discontinued the Becca Ever Matte primer recently, so I decided to try Make up Forever....& they UNDERSTOOD THE ASSIGNMENT!! I actually like this brand's primer better because it kept me matte much longer than the Becca brand. For transparency purposes, I live in NYC so the weather is getting a bit cooler now but I will be in Florida next month so I can give this primer a REAL test! Also, I used the MF light velvet air setting spray along with it so that may have helped to keep my makeup on a bit longer w/o blotching. I will be purchasing the bigger container soon to keep on hand.
