As with liposuction of any other part of the body, the key to a nice result from liposuction of the arms is the pre-existing condition of your skin. If you have significant loose, excess skin, as your photo shows, then you can expect that the skin will seem even looser after removing some of the fat that is filling it out. This would leave you with floppier skin. Liposuction alone only works well in the arms when the skin is firm enough that it can redrape smoothly over the reduced fatty layer after surgery. Otherwise, you would need an armlift, a brachioplasty, to tailor and remove the excess skin. This is a good operation that can trim and firm the arm, but does leave a long permanent scar down the inside or back of the arm. Although many patients will gladly accept this scar as a worthwhile trade-off, others feel it is not worth it for them and choose to live with the loose skin.
