I appreciate you asking this question. As a result of my experience, I think that defining body contour and marking the extremities must be done in a complete manner to obtain a harmonious result. If the procedure is performed only on the arms, perhaps the result will be discordant with the rest of the body. I suggest liposculpture of body contours with marking and definition fit for the arms, perhaps in your case Jplasma is required to give more tension to the skin and avoid sagging. Liposculpture may or may not be associated with technology. Conventional fat extraction techniques can result in lumps or retractions beneath the skin. We extract fat from the use of laser technology, which is light, or vaser, which is internal ultrasound associated with microair (PAL- Power assisted liposuction). The first two devices allow us to vase or Laser produce lipolysis (is to pass the fat of a solid state to a liquid state so that there are no irregularities under the skin) and the microaire or the PAL allows us to make the extraction of the melted liquid without so much trauma. You have not only liposuction-related sequelae, but from what I can see from the pictures I think you could have a little diastasis of the abdominal muscles secondary to pregnancy. The case should be evaluated a little further in order to determine if an improved lipolysis can only be achieved with a new combination of technology. In a lipolysis of only the body contour, we will be able to improve the appearance by 50% to 70% of the result you currently have; because fibrosis acts like a scar inside the body and can be very difficult to completely remove. For the skin that is flaccid, in order to increase the reaffirmation, we use a treatment called Jplasma, an equipment called Renuvion, this gives off plasma energy that allows collagen to retract deep within the tissue. The liposculpture that we practice is associated with Vaser technology is an internal ultrasound and laser which is a form of light that is produced to break down the fat, these two equipment produce lipolysis, that means to pass fat from a solid-state to a liquid state. The result is that patients are not left with fibrosis or irregularities under the skin. We also use microaire for the extraction of liquid fat, and in the final part, if the patient requires it due to loose skin in specific areas, like the arms, back, abdomen, etc, we use Jplasma, which is a specialized instrument. For the back, the ideal would be definitely to do an lipolysis associated between vaser and microaire combined with j-plasma to produce skin retraction (it is a tension inside the skin), and finally also a back lift, leaving a scar for remove excess of the skin that is left over. The reduction of fat through high-tech equipment and skin reaffirmation, will give us the best result.
