Thank you for questions regarding loose creepy upper arm skin. There are several options for the treatment of loose upper arm skin. For definitive treatment of this area, I would suggest either a crescent or a mini-brachioplasty or arm lift. During the surgery, a crescent area of arm skin is removed from the upper, inner armpit. An incision is made and hidden in the armpit. This can help to remove excess upper arm skin. I think that would be your best alternative. Other alternatives would be a modified “T” arm lift incision, where the aforementioned crescent or mini-brachioplasty is performed with a slight extension down your inner arm. This is a larger scar and removes more excess skin. However, based on your single picture I do not think you need this type of arm lift. The more extensive arm lift would be an incision from the armpit to your elbow. Based on your single picture, I do not think you need this type of arm lift either. Another alternative may be J - plasma. This may help to tighten the skin, but in your case, I do not think would be a definitive cure or solution. I do not suggest liposuction in your case. Liposuction would lead to further skin laxity and worsening of your arm condition. I hope this information helps. If you have any more questions regarding treatment of your arms, please contact me. Either a crescent arm lift, mini, modified “T” full incision arm lift or J-plasma treatment should work. Good luck. When considering arm lift surgery, please seek an experienced, board-certified plastic surgeon. Travel if you must. Sincerely, Dr. Katzen
