With a full tummy tuck, also called full abdominoplasty, the scar tends to be long, from hip to hip.
However, the scar is hidden (but not always) in the lower part of the abdomen, above the pubic area. So, it can be concealed by swimwear bottoms or underwear.
Only in patients who need a large amount of skin removed will there be double the scars—one horizontal from hip to hip, and a vertical one from the belly bottom to the breastbone. Scars will fade over time but won't disappear entirely.
