Tattoo removal gone wrong! Raised scarring. Any treatments to flatten or tighten? (Photo)

Hi, been butchered by a untrained laser tattoo removal person who had fake qualifications otherwise would not have used! Ive got raised scarring and wondered is there any treatments to use to flatten or tighten loose skin so i can get covered up with another tattoo? Tryed co2 laser and skin peels so far , peels helped little but not no more and co2 was useless, please any advice be greatly appreciated!!
