Treatment of red scars on the skin
Long term redness of scar
You would need to see a dermatologist or plastic surgeon, but there's a good chance that a vascular laser like Vbeam could reduce the redness. Expect it to take several treatments to gauge how effective it will be for your particular situation.
A vascular laser will "seal" tiny vessels that are close to the skin surface.
