Dermarolling after hair transplant?

I am looking to get a beard transplant in my Goatee area in the next few months. I have seen a fair amount of success using a 0.5mm Dermaroller with Rogaine on my hairline and sideburns. 3-4 months after my beard transplant (giving it time to heal), will I be able to continue using the Dermaroller on my hairline and cheeks (careful to avoid the transplanted goatee area)? I can’t imagine it would be an issue if I avoid the transplanted area but better safe than sorry! Thanks for your help!
