Will an arm lift help for crepey loose skin on a lean person?

Thank you for your question! Yes, an arm lift will remove both excess skin and fat to your arms. I recommend consulting with a board certified plastic surgeon, who can assess you in person, and create a personalized plan for you. Best of luck!

It’s difficult to say too much without photos but an armlift may be beneficial especially if your skin has very little tone. The scar from an armlift is not small so you are the only one who can say if the contour improvement is worth the scar. I would recommend seeing a board-certified PS to see some before and after photos so you can determine if the procedure is worth it. Best regards. 

The arm lift will remove much of the loose skin, but will not help the or quality of the skin. Fortunately, the brachioplasty skin which is removed is the very skin you are talking about. Much of the thicker skin which is usually in better condition, is retained.
