Should I massage the hard scar tissue after chin implant removal? It's been 3months.

This is really important for me because i have no idea what to do. Its been 3months since the removal of my small 5mm silicone extended anatomical chin implant which stayed in very short time. Its been 3months some parts soften but in the center of my chin and the area above incision side is still very hard like a bone i guess its scar tissue right? Should i massage that area? To soften ?? Please tell me i dont want to mess it
