I would advice you to schedule a consultation with a board certified plastic surgeon to be assessed in person. First, it needs to be determined if you actually keloid. Then, you'll need to decide if the risk is worth it. The incisions for liposuction are quite small and can typically be camouflaged but it will depend on the area being treated. Hope this helps.
You would have to be evaluated to make sure you actually form keloids. If you do, then you might develop one at the lipo incision sites.
