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.
Recovery. Average recovery time after a tummy tuck is generally two to four weeks, at which point many patients can return to school or work. The scars from the procedure usually take longer to fade and heal. In some cases, it can take a few years for the scars to heal considerably. 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.
