"I absolutely love this!" a reviewer wrote. "I have used so many that were not helping. I have very big pores! I tried so many of the big name make up companies and paid a lot of money to always be let down. When I first put it on I was like yeah! It's working! I just wanted a smoother looking face and this did the trick much better than anything I have tried. My foundation and powder now looks so smooth."
