Has my skin been pulled too tight after an arm lift? Will it stretch? (Photo)

It is still too early for you to show signs of pulling that is too tight. So far your photos look fine. If you are really concerned, reach out to your surgeon and discuss your concerns and inquire how long before you should have your final results. 

I believe it is too early to tell. You were still healing. I believe with time your arm should heal.In terms of treatment at this time, I would suggest deep tissue massage. I believe most of your arm pain is due to swelling. To minimize arm swelling,  I would suggest arm compression from the wrist to the elbow 24 hours a day.The skin will stretch a little, however, not too much.  I would reassess everything six months after your surgery.I hope this answers your question regarding arm lift or brachioplasty.  Sincerely, Dr. Katzen

Thank you for your question and sharing your photo.  You will very likely find that with each month the arm feels more supple.  It may take a good several months before you stop seeing less change in suppleness.  I would also recommend you continue doing what you are doing in terms of massage and also would recommend using silicone pads on the incision.
