Thank you for your question regarding whether you would be a good candidate for arm liposuction or if you might need an arm lift. It's great that you're considering options to enhance the appearance of your arms. It's hard to tell from the photos provided if you have any stretch marks on your arms. If you do have stretch marks, this typically indicates less skin elasticity, which might make you a better candidate for an arm lift (brachioplasty). An arm lift would not only reduce excess skin but also tighten and contour the remaining skin for a more toned appearance. At 31 years old, you are relatively young, and your skin likely retains some natural elasticity. This means that your skin might partially "snap back" post-procedure, but not 100%. If you don't mind the scar, which is typically placed on the inner aspect of the arm to be less visible, I would recommend considering the brachioplasty to achieve the best contouring result. However, if the idea of a scar is concerning, another option to consider is arm liposuction combined with a procedure like BodyTite. BodyTite uses radiofrequency-assisted lipolysis to tighten the skin while removing fat. This can be a good compromise to see how well your skin retracts with the aid of technology designed to enhance skin tightening, especially when combined with tight compression garments post-procedure. I recommend discussing these options with a board-certified plastic surgeon who can evaluate your skin quality and the amount of fat and skin that needs to be addressed. This consultation will help determine the most suitable approach to meet your aesthetic goals and ensure you are satisfied with the results. Sincerely, Dr. Katzen
