I've already used Glass Glow Serum for 3 bottles and now I got the renewal one 2.0!! I'm so glad there are upgraded effects on 2.0 and I'm so excited to apply them!! I can feel more hydration and collagen effects on my skin and double up my skin condition! Love it and will keep using Glass Glow Serum! :)
my experience was great. product does what it is suppose to do. be using for a long time.
