Whoa - this is an AMAZING product. Truly, the only oil control product that has ever worked for me. I use this with powder, liquid and cream foundations and it really DOES keep my makeup unshiny and in place all day long.
My skin is super oily - shiny all the time, no blotting powder or mattifier has ever worked well for me at all. I had my doubts about this one, and the first time I tried it, thought "eh." I used it in the afternoon - after my makeup was already shiny. Figured out the next day that was a mistake.
With this product, I get the BEST results using it over sunblock but under foundation. Spritz a few times, let dry a few moments while I lay out my products. Apply my makeup as usual, then mist it again 3-4 times. By sandwiching my makeup, I have a perfect, just-applied finish for at least 8 hours. If I need to refresh, I just blot the surface, spritz, then lightly repowder - set for another marathon!
No clogging, no breakouts, I love that the product is scentless, too. Just all around a winner!
