I am currently wearing this product now. I ordered it a week ago and can't understand how I have survived without it all these years. I have used other primers before, none have been quite as satisfying as this one. I do have one concern though, do I need to let it dry for awhile after application? I usually wait a minute or two but when applying my concealer, it tends to clump up in some areas. Other than that concern, I love it - simply because it does what it say it will do. My makeup stays looking fresh throughout the day, which is very important to me considering I have VERY oily/shiny skin. Great, great, GREAT product!
