I had radio frequency 1 week ago to smooth out edges from previous mole removals on my face (via shave excision). No deep cutting of the dermis was involved. I want to start dermarolling to even out the tone and texture after these heal but I don't want to cause worse damage. I am also using silicone scar sheets at night on the spots where the scabs have fallen off and I am awaiting an RX for PracaSil silicone gel. How long should I wait to start dermarolling and what length needles are advised?
