36 y/o. 136lb. Mother of 2. 1 natural birth, 1 C-section. Athletic, strength trainer, jiujitsu competitor. I am NOT trying to change my stomach appearance. I am only trying to smooth my external skin with a bit of tightness. Will CO2 fractional laser & RF microneedling help give my stomach a smoother appearance's? Or would I need a more invasive procedure like Lipo etching with Renuvion ?
