Recent publications show that heat-mediated tissue tightening is a promising treatment for the lax abdomen and may provide better long-term outcomes than traditional suction-assisted liposuction (SAL). The author evaluates the degree and duration of skin surface area contraction, as well as the influence of anatomic location of the treatment region on the degree of tissue tightening, in a study comparing SAL alone vs SAL plus radiofrequency-assisted liposuction (RFAL).
