Can i advise that you discuss with your doctor about subcision and filler placement first? That would help improve the undulating appearance of your scars.
TCA Cross can widen scars if done poorly (technique wise) by having excessive spillage into the normal skin, or if the scar selection was done wrongly. Find an experienced practitioner for this treatment modality.
Post TCA pigment wise - sunblock is key! and you can use Q switch laser to reduce it 2-3 weeks after the therapy.
Hope all goes well and Merry Christmas!
