Sagging skin mainly affects the arms, inner thighs, knees, abdomen and buttocks, and is caused by sudden changes in weight, aging or pregnancy. It may or may not be associated with muscle flaccidity, which consists of a generalized or localized lack of firmness in muscle tone.
Carboxytherpia consists of the intradermal injection of CO2 at the subcutaneous level (insufflation). This technique causes an increase in vascularity and stimulates collagen, which causes a tightening effect on the skin that attenuates the lack of firmness.
