Thick and Red Belly Button Scar After 5 Months Tummy Tuck PO? (photo)

The demonstrated remodeling scars of the navel and horizontal incision are still biologically quite active. They will do better with time. There may be some benefit of judicious use of intra-lesion steroids.

Try steroid injections to "red" areas of the bb. Before considering revision surgery and the risks of MORE scars. 

The belly button is really the most noticeable scar from an abdominoplasty.  You can cover the lower transverse scar but the belly button is right out there.  It appears that you have a hypertrophic scar which may be due to tension.  At this point some judicious use of Kenalog and 5- FU may be beneficial.  Otherwise you may need a scar revision in the future in this area. I have my patients place a Mack's silicone ear plug in their umbilicus.  Silicone has been shown to decrease scarring and improve healing.  

You definitely are a hypertrophic scar former and it's going to take a long time for these scars to settle down, but eventually they do improve. A revision would probably result in the same type of scar so I would not advise that. Dilute steroid injections can be very useful and help scars like this improve much more quickly. Your surgeon can help you with the details of these treatments. Have you tried to apply continuous pressure to your scars with silicone sheets? There are many brands available at the drug store and they have been shown to be helpful too. Best of luck, you do have a nicely done tummy tuck!
