Dark, raised scars two years after liposuction—what are my options? (Photos)

I’m two years post-lipo and have five scars that are still very dark and raised. Could these be keloids? I had surgery to feel better about my body, but the scars have really affected my confidence, and I don’t know where to start. Can surgery improve them, or could they come back worse? Would injections or laser help with both the texture and colour? Is this usually one treatment or several? I’ve also seen scar camouflage tattooing, but because mine are raised, I’m wondering whether that would even be suitable. I’m in Ontario, Canada, but willing to travel. I’d really appreciate honest advice about what improvement is possible and recommendations for someone experienced with scars like mine. Photo attached.
