Oh my! This is fabulous! I recently started using the Tria laser, and the Tria eye laser and after increased my treatment level I definitely needed something cooling, this did the trick! I also use it in the AM and it shrinks my pores into nothing and completely depuffs me ready for a NuFace treatment. My daughter had a bit of a topical skin soreness from some stage makeup the other day and used this to calm and cool it all down. It feels amazing even if you just want to sit and use it anytime, which I do :) Completely addicted and have used it everyday since it arrived. I was upset to not have the samples of the serum with my order, as I hate to buy things unless I try and skincare is a funny one with my skin, but I found that using my normal Argentum, or Herbivore serums after yielded great results, so I will more than likely not both with this brands serum.
