My question is about what to use with the dermaroller...if i should use alcohol to disinfect it. Some sites say to use it but at least one site said not to because it helps to wear it down. Also should i use an antibacterial soap on my face before i use the roller. I think of antibacterial soap as too harsh for the face. after using the dermaroller i was planning on applying a mary kay product that is a serum for night use but im not sure if its safe.
