Any advice on what I can expect regarding scarring from a body lift?

The lower bodylift surgery is essentially an abdominoplasty scar in the front, plus the same type of scar in the lower back.  The surgery is circumferential (Tummy tuck in the front, thighlift on the sides and buttocklift in the back) and the scar is placed as low as possible to anatomically best contour the body, while keeping the eventual scar hidden in bikini bottoms or underwear.

Scaring after body
lift in general is not a major problem.
Patients after major weigh loss normally have loss skin that produces reduction
in tension allowing the tissues to heal kindly.
Arms are predisposed to produce thicker
scar but using careful surgical techniques to close the skin can minimize those

Brachioplasty and Body Lift Scarring

In general, most surgical body lift procedures will leave long scars - this is because it is the only way to remove a lot of redundant skin. The scarring on your arm would be minimized by having it on the underside of your arm towards your body and is often hairline in appearance. These may fade to white or widen and stay red for considerable periods of time before they heal. Scars can sometimes be improved with topical medication or lasers but will never completely disappear. This is usually considered a worthwhile trade-off by most patients to remove all of their unwanted hanging skin and fat.
