Review (2/5): BURNS!
I've been using this product for a week or two - right on my T-zone, and on top of the Booster Serum. It made my foundation slick and goopy, so I was just using it at night. Okay at first....then it started to sting a bit (hey, I figured it was working), then 2 nights ago...OOOOOWWW! Got up to look in the mirror and my entire T-zone looked cooked! Washed it off, and everything was fine. Last night, I applied just the Booster Serum, and all was well again. Note - I do not have sensitive skin! Yikes!
