Will laser tighten loose crepey skin on arms?

While we usually think of Fraxel lasers as being used solely on the face, they can treat almost any other area of the body as well. Both Fraxel Re:Store and Dual will heat the underlying collagen layer, forcing it to contract, which will also shrink the skin. The lasers stimulate the production of new collagen and elastin – the building blocks of the skin's supportive matrix. Whether Fraxel is sufficient to alleviate the sagging on your arms, however, will depend on how much sagging there is and the quality of your skin overall. This will be determined when you consult with a board-certified dermatologist who has expertise using lasers to resurface and tighten the skin.

A combination approach will give the most improvement.  Fractional laser like Fraxel can help increase collagen as well as a combination of Sculptra and radiofrequency treatments like venus legacy and thermage to help increase skin tightening in this area. .  Best, Dr. Emer.

For tightening of the skin on the arms (upper arms for example) I recommend devices like the EndyMed. Its a pretty comfortable procedure and treatments can be repeated every 2 weeks. After a few treatments you should see some tightening of the skin. The beauty of this device is it can be used in all skin types and is non-invasive.
