Hi, i am going to get laser done on my upper cheeks area on my face. However, i am a bit worried about the type of laser they are using, which is the EpiTouch ruby laser. I know it is an older laser but was wondering if anyone has had any experiences with it? Also, what kind of risk of scarring is involved with it? And finally, how much time is required for the immediate side effects(swelling, red bumps ect.) to disappear?
