Peter Thomas Roth VIZ-1000 (hyaluronic acid) is a great hydrator. I use it with Ole Henricksen Vitamin C as a serum. I like how the two products work together and make my face feel, so much, that occasionally I forget to add moisturizer after the serum mixture.
Sometimes, I will add a drop or two of the VIZ 1000 to my liquid foundation. If you do add the VIZ 1000 to foundation, make sure you mix it well, before applying the mixture, to your face.
