Thank you for your question about treating the forearm after weight loss. It appears that you have crepe paper skin on the forearms. This can be a combination of weight loss, genetics, and sun damage. Whatever the cause, I'm sure you are more concerned and interested in the treatment. Surgical treatments include a forearm lift with an incision from the elbow to the wrist. However, That will eliminate only some of the wrinkles. I would suggest mechanisms that change the skin texture in your particular case. I would first start with a 35% TCA peel. You may want to use this on a localized area to see if it helps significantly. Additionally, you may want to consider a laser for skin resurfacing. This will help to eliminate wrinkles. I specialize in arm lifts. I hope that I have answered your questions regarding the arm reduction. If you have any more questions regarding the arm lift, arm reduction, brachioplasty or arm crease fat grafting, please contact my office. Since a brachioplasty or arm lift surgery is a difficult procedure, please seek an experienced, board-certified plastic surgeon with significant experience performing these types of arm lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 100 arm lifts. Make sure they have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. Sincerely, Dr. Katzen.
