Thank you for your question regarding sun-damaged, upper arm skin. The sun’s radiation damages the skin. Among other things, the sun’s radiation damages the elastic fibers in the skin. This reduces the ability of the skin to recoil. This leads to loose, wrinkled skin. Almost all skin that is exposed to the sun can become wrinkled. Sun damaged, wrinkly skin on the front of the arm is common. Since you have excess arm skin, the only way to effectively remove this arm skin is to have an arm lift / arm reduction / brachioplasty. If you just have excess arm fat limited to the upper arm, you may only require an incision in the armpit. This type of arm lift / brachioplasty is called a crescent brachioplasty. If you have slightly more excessive arm skin, you may require a slight extension of the crescent brachioplasty. With this slight extension, the incision then changes from a crescent brachioplasty to a modified T brachioplasty. If you have a significant amount of excess skin throughout the upper arm, you may require a full brachioplasty. This type of arm reduction incision does not involve a crescent incision in the armpit. This type of brachioplasty or arm reduction involves an incision from the armpit to the elbow. Most arm lifts / arm reductions / brachioplasties take two to three hours to perform. Most arm lifts are performed under general anesthesia. Typically, patients are able to return to work one or two weeks after their arm lift.I hope this answers your question regarding arm lifts / arm reductions / brachioplasties. Good luck! If you have any more questions regarding the crescent, modified T, or full arm lift or brachioplasty, please not hesitate to contact my office.
