Loose upper arm skin is most often
related to weight loss. After weight loss, the skin often fails
to tighten, and so it sags. The only way to improve this problem
is through an arm lift, also called brachioplasty.
Liposuction is not an option since
the skin is already loose.
The resulting scars are the greatest
drawback, since they extend from the armpit to the elbow, along
the inside of the arm. Those with only a small amount of looseness
will probably not want the scars.
