This is meant as a makeup primer / pore hider. It's oil free (huge plus for the oily skinned girl like me) and can be used under or over makeup. Yep, I said over makeup. It's silky and smooth with just a hint of tint. It blended right over my tinted moisturizer and didn't disturb it. My pores look smaller and smoother after application and appear that way for several hours. The nice thing is that you can touch up with it if you have a dinner date and no time to run home. I thought it fought my usual shine problem very well and compares favorably with my favorite primer - Clinique Pore Minimizer Instant Perfector. It also has the added benefit of not affecting the finish of my mineral makeup. It applies smoothly over the POREfessional and has no added shine or texture.
This is now appearing in several retail chains including Ulta and Sephora for $28. It's fairly pricey and almost double what I pay for the Clinique - but it's a larger bottle, so I'd say it will just stop you from purchasing as often. It's a pretty impressive product and I've been testing it in 90+ degree weather for the last 2 weeks. So its a great consideration for those that have a desire to hide the appearance of their pores and control shine.
