For patients with significant skin laxity, there is no substitute for proper skin reduction surgery. From first-hand experience using Renuvion, a.k.a. JPlasma, I noticed zero skin tightening, and none of my patients noticed any significant difference. Liposuction alone could explain all the results and some skin retraction, which happens from Liposuction inherently. Delivering consistent quality, Liposuction results is more difficult than most people believe. Upper extremities are technically challenging, and finding plastic surgeons who truly mastered arm Liposuction is not easy. Personally, I treat arms circumferencial. He typically blend Liposuction into the forearm. The procedure will create some skin contraction and most patients appreciate arm reductions with the arm in a down position. If you lift your arms out, you will still have skin laxity. A significant number of patients are apprehensive of having arm lift surgery. A.k.a. brachioplasty because it tends to leave a visible scar. For that reason, the majority of patients put up with skin laxity and except quality liposuction as a fairly good compromise of a reasonable procedure giving some improvements. you can look at before and after pictures under photos on my profile on this website to see what arm Liposuction results can look like.
