there are multiple modalities to help reduce scar but you may want to consider a surgical scar reduction procedure for best results.
My navel piercing rejected and now I have a raised scar?
Thank you for sharing your question and I am sorry to hear of your scarring issues. Attached is a link with some over the counter and inexpensive remedies that you may find useful to improve your scar appearance but at a year from its development surgical revision may be needed. Hope this helps.
Keloids/Scar -- Fraxel, 5fu/steroids, pulsed dye/vbeam/yellow laser, microneedling/PRP, surgical removal
I suggest injections to treat this area. It can be improved with lasers, injections and even surgery. Best, Dr. Emer.
