I've been testing this serum for 3 months now and I really don't see any difference. I use this in the morning before I do my makeup. It does give a nice glow but that glow is only for a while. I now use it as a primer under my makeup and now my makeup looks more fresh and healthy. So he does get points for that. But if you're looking for something for real results? Then I wouldn't go for this if you have normal to combination skin.
