I was really excited to try this Vitamin C serum because so many people raved about it. I'm not sure if its because I was expecting so much, but it didn't really do anything for my skin. Once you put it on, it gets absorbed quite quickly. Although, it remains sticky for at least an hour or so.

I haven't noticed a brightening effect (I applied this all over my face) and I haven't noticed any of my PIH getting lighter. Granted, a lot of my dark marks are quite deep and old so that may be a factor. In any case, it's not terrible, but I'm not sure if its worth the price for me :(
