Loose skin after liposuction. What can I do to tighten my arms? (Photo)

From the provided photo it appears you will have the best result from an arm lift. You may have some improvement from non invasive options but due to the amount of laxity it will not likely be the same as the surgical option.

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.

Morpheus8 body would be a possible minimally invasive solution for your residual loose skin. A single 4mm depth treatment would cause muscle contraction, skin tightening and even a little additional fat destruction.
