Will laser tighten loose crepey skin on arms?

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.

Morpheus 8 is a non-invasive skin and soft tissue tightening treatment that is consistently amazing in our patients. We use the Morpheus to exact fractional induced RF into the skin or tissue in order to tighten collagen and stimulate contraction of the tissue. For acne scars, it is quite useful to build collagen in patients who have atrophic scars but is not very productive for ice-pick scars which require TCA Cross. For tissue tightening, Morpheus is ideal for the face and neck and we often combine it with CO2 laser or Ultherapy to further enhance results. Chemical peels and skin resurfacing should be done at least 5 to 7 days after, but can be performed earlier, depending on treatment severity. Avoid exfoliating skin treatments before Morpheus and expect a period of 2-4 weeks for skin contraction to set in.

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.
