I bought this product due to the rave reviews I've read everywhere. I've been using it for about 3 weeks now and have yet to see results, but I'm patient! I've read that really seeing results can take quite a while.

The only bothersome thing is that it leaves my face quite sticky after it has dried and the wait time of 20min has passed. So the C20 serum isn't suited for use in the mornings because you really do need to rinse it off after it has done its magic.
