Tummy Tuck Scar Treatment. Diagnosis: If the tummy tuck scar is flat and discolored only our scar cream is required. If scarring is raised and/or indented silicone sheeting is required. For maximum results we recommend our discounted scar kits that combine silicone sheeting and scar cream for the treatment of the scarring.
Procedure. A tummy tuck is a relatively straightforward surgery. The surgeon makes a horizontal incision above the pubic area. A second incision may be made above the belly button if there is excess skin around that area. Then the extra fat is removed, and the loose muscles are tightened with sutures. tummy tuck, also called an abdominoplasty, is a plastic surgery procedure in which the excess fat and skin around the abdominal area is removed. In some cases, torn muscles are repaired to further strengthen the abdominal wall.
