Just wondering, can I use microneedling at home with my obagi nu-derm system? I have a scar on one of my cheeks and I wanted to use microneedling on it to fix it was wondering if I can do that whilst I am on the obagi system or do I need to take a "day off" from obagi to do this? I was thinking of using a copper serum with the microneedling-what is the most effective serum to use with microneedling?
