It all depends on just how much fat you have in your arms AND on the amount of arm skin looseness.
When the skin tone is great and there is only a bit of annoying giggly fat, a liposuction without any other procedure may suffice to obtain a good result.
When the arms are thin and devoid of fat after a large weight loss but the skin is very loose ("IE Bat wing Deformity), only a formal arm lift with a scar along the inner aspect of the arm can fix this deformity.
But - when you have a component of BOTH excess skin and excess arm fat then liposuction needs to be combined with a Brachioplasty procedure. In some cases, when the arms are full of fat, the patient may even benefit from two separate sequential (IE staged) procedures, where liposuction would be done first circumferentially. The patient would be allowed several months to recover and then a Brachioplasty would be done after the extent of skin shrinkage has maximized.
Good Luck.
