I have a scar after laser tattoo removal. I've tried Fraxel and CO2, but they didn't work. Can Derma Roller help? (Photo)

Hi doctors. I have a scar after a laser tattoo removal and did already two Fraxel dual treatments and one CO2 for this scar. It didn't work to reduce the raised part or the hypopigmentation. Do you believe the Dermaroller can help? Thank you.
