55 y.o.; 5'2", 110#. I have some fat and loose skin on my upper arms. I don't want brachioplasty, I'm not a candidate for short-scar arm lift, and if I were to get lipo now I don't have enough elasticity for the skin to retract after the reduction in volume. If I get sculptra in that fatty area, is it possible that it could bring back enough elasticity to be a candidate for arm lipo after about a year or so?
