Thank you for your question regarding the non-surgical arm lift option for loose skin. Since you asked this question in August 2010, it has almost been ten years; the technique does not work. Ultrasound and red ultra-rays do not remove loose arm skin. The only thing that permanently removes loose arm skin is an arm lift, arm reduction, or brachioplasty. Radiofrequency may tighten the arm skin a little, but not much. Therefore, consult with a board-certified plastic surgeon and don't necessarily jump on the latest and greatest new technique. Experienced plastic surgeons rely on procedures that are known to work overtime. Thank you for your question regarding the new, non-surgical arm lift option for loose skin. I specialize in arm lifts. I hope that I have answered your questions regarding the arm reduction. If you have any more questions regarding the arm lift, arm reduction, brachioplasty or arm crease fat grafting, please contact my office. Since a brachioplasty or arm lift surgery is a difficult procedure, please seek an experienced, board certified plastic surgeon with significant experience performing these types of arm lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 100 arm lifts. Make sure they have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. Sincerely, Dr. Katzen.
