Hi jasmine1221, Thank you for your question regarding an arm lift on a person with creepy, loose arm skin. The simple answer is "probably yes". Before you undergo an arm lift, it is very important to be examined to be examined by an experienced, board certified plastic surgeon who has performed hundreds of arm lifts. Most patients seeking to undergo an arm lift have excess arm skin and arm fat. However, about 20% of my practice just have excess arm skin. Since you have excess arm skin and not much excess arm fat, I seriously doubt arm liposuction will help. However, it's impossible to determine what arm surgery you require without a physical examination or pictures. Thank you for your question regarding loose, creepy arms skin in a lean person. Good luck. If you have anymore questions regarding an arm lift or brachioplasty, please call my office. Sincerely, Dr. Katzen.
