Before considering scar treatments, it’s important to first get quality assessment to understand what the problem is. Scar issues typically come down to a few different variables. In terms of the character of the scar itself problems can often be divided into scar hypertrophy or keloid type scars which are thick and hard or hyperpigmentation the problem is purely skin color, not shape or texture. For scar hypertrophy silicone sheeting that can be helpful, but it typically needs to be used for many months before it has an impact. Scar hyperpigmentation is more challenging and will not typically be improved from the silicone sheeting. For most individuals hyperpigmentation subsides with time, but when it’s present for more than two years, it may be difficult to reverse. Sometimes laser treatments can be helpful, but if done incorrectly on the wrong patients Laser treatments can potentially also make things worse. Whenever we consider revision, we need to ask ourselves will scar heal different differently by redoing the surgery. In your case, there may be different scar issues and each one may need to be assessed differently. I don’t think PRP will do much and. CO2 laser may not be the best option for hyperpigmentation. I suggest having a few in person consultations with plastic surgeons in your community. Simply redoing the scar is not a guarantee that it’s going to heal better. Lumpiness or nodules in a tummy tuck scar may result from larger sutures used to sew together the skin edges, which are usually had significant tension during the first procedure.
