Since a tummy tuck requires an incision in the lower abdomen to remove excess skin, scars are unavoidable. I am careful to make the incision in the least noticeable area, beneath the bikini line. In a standard tummy tuck, the incision will be a gentle curve that follows the skin creases from hip to hip, and the length will depend on the amount of extra skin. There is also a small scar within the belly button, but this is not easily visible.
The "silver lining" with tummy tuck scars is that they fade with time. Depending on your genetic predisposition to scarring, most fade within 6-12 months and can be treated with lasers to improve their appearance if needed.
