When injections reduce upper-arm fat, and when they do not
A thick, soft layer that can be pinched at the back of the arm when you raise it to the side is usually subcutaneous fat, and this is the layer an arm fat-dissolving injection targets. Touch alone cannot rule out swelling or other tissue, so we confirm at the examination.
If the pinch is thin but the skin hangs and moves, laxity matters more than fat. Fat-dissolving injections do not tighten loose skin, so we discuss a skin-tightening treatment as well, and we do not recommend injections for firm, muscular arms.
