Scar on penis from laser hair removal! Worried about cortisone injections. Area sensitive. Tried products but made worse. Help!

I had a pre-existing anatomical scar on the base of my penis. Laser hair removal burned the area. After healing the flat scar is now raised. My derm gave me cortisone cream, followed by Silagen (silicone gel). If that didn't work then cortisone injections. The cortisone cream helped a little. The Silagen irritated the area and made it worse and Scarguard MD also made it worse! I'm worried the cortisone injections may cause an indentation. The area is sensitive. Not sure what to try. Please help!
