Radiofrequency-Assisted Liposuction Compared with Aggressive Superficial, Subdermal Liposuction of the Arms: A Bilateral Quantitative Comparison.

Background: Liposuction of the arms alone may be inadequate for aesthetic improvement because of skin laxity. Radiofrequency-assisted liposuction (RFAL) and aggressive superficial liposuction (SupL) have been described to stimulate soft tissue retraction to improve results. We compare the techniques and describe a classification scheme that factors skin laxity, skin quality, and Fitzpatrick type to provide treatment recommendations.
