I had been curious about foundation primers for a long time and finally decided to give one a try. I chose Smashbox because the reviews generally were great and because the company has a good reputation. I am an "older" woman who has always received compliments on my skin and been told that I look younger than my age. I use this product after my regular moisturizer and I do think my foundation goes on more smoothly. Also, some mornings I've been so rushed that I forgot to use my moisturizer and didn't realize it until it was too late (unless I wanted to wash my face and start all over). On those days, my skin felt and looked great with the primer alone. I think this product is worth the money and I plan to keep using it.
I have used other Smashbox primers and were great. This particular 'specialized' primer I was trying for the first time and not happy with it as it is very, very fluid almost like water. Would not recommend it.
