I would suggest a combination of Plato's Scar Serum, surgical scar revision with layered closure, subcision, and fillers for your scars.

Lasers, surgical revision, subcision and fillers can all be tried and used. I suggest you see an expert for an evaluation. Best, Dr. Emer.
It might be possible to improve this scar by injecting filler into and under the scar to lift it. Another option would be to surgically excise the scar and resuture the wound to create a finer line. I would get an opinion from a cosmetic dermatologist or plastic surgeon.
