2 years post Tummy Tuck with an ugly scar. Would a revision help its appearance or do you recommend other methods? (photos)

you appear to have ares of scar widening and hyper pigmentation.  This can happen if there was something wrong with the healing process (too much tension? infection? ...) however given that the entire scar seems like that, I would suspect that you may be one of those unfortunate people who always heal with a widened and hypertrophic scar.  If you wish to undergo a revision, it may help.  If your scar turns out the same way again, they you know that unfortunately there's not much that can be done.  Additionally, your scars is very visible because of the discolouration.... laser to lighten the pigment may be helpful in making the scar less obvious

Thank you for your picture. Yes, a scar revision will help you greatly. Please seek several consultations from board-certified plastic surgery.Good luck.Earl Stephenson, Jr, MD, DDS, FACS

Two years is a very reasonable time to consider scar revision.  The Catch-22 of tummy tuck is that patient and surgeon alike want the abdomen tight but tension on a healing can cause the scar to be unfavorable.  If there would be minimal tension on a revised scar, then it makes sense to revise and expect an improved scar.  Assessing the tension on a revised scar can only be done by physical examination.  Now is a reasonable time to return to your surgeon to discuss scar revision.

YES ! scar revision is indicated for improved appearances. Seek IN PERSON opinions from boarded PSs in your city. 

Thank you for the question and pictures. Assuming there is enough laxity above and below the wide scars, scar revision will likely provide you with the best improvement. Best wishes.
