I used melederm last year and it did work pretty well. Just a few days after I started, my face was looking smoother and less red. After about 2 months, alot of the red scars had lightened on my face. There were some darker ones that didn't fade, but overall my skin was looking much better. I kept using it for another 3 months and the results started slowing down so eventually I stopped. But I really did like the improvements it made on my skin in a short time and would recommend it. If I had more money to spend, I would have kept using it.
