Hello LisaAnn, Thank you for your questions and photographs. Judging by the pictures, you appear to have good muscle tone in your arms but some excess skin, too. If your skin laxity is significant, a Brachioplasty is the most effective solution, while RF or J-Plasma may help in mild to moderate cases. Brachioplasty (Arm Lift) – Best for severe sagging, this surgery removes excess skin and fat to reshape the upper arm. It results in a scar along the inner arm but provides dramatic tightening. If you don't want a surgical scar, these are other options: Minimally Invasive & Non-Surgical Options Liposuction—If excess fat contributes to sagging, liposuction can help contour the arms. However, it doesn't significantly tighten significantly loose skin. Renuvion (J-Plasma) uses plasma energy to tighten skin. It is often combined with liposuction for mild to moderate laxity. Radiofrequency (RF) Treatments: Devices like Morpheus8 or Thermage use RF energy to stimulate collagen production, resulting in mild tightening over time. However, to assess what could help, an in-person consultation is necessary. I recommend seeking several consultations with experienced, board-certified surgeons to discover your options. Good Luck, Best, Dr. Adam Kinal
