DEEP HYDRATION EYE SERUM

I’ve been using this twice a day for a few weeks now. The improvement is slight, but I like the cooling effect the roller gives. The main issue I have is with the pump. It is very difficult to pump the serum out and I have to spend a long time trying to get the serum to come out so in the end I give up and I end up with very little product. That might be why the progress is slow as well.
