The alteration commonly defined as "fluid retention" refers to an accumulation of fluids, usually in the lower limbs. The treatments consist of hygienic-dietetic measures and elastic compression.
Carboxytherapy consists of the intradermal injection of CO2 at the subcutaneous level (insufflation) and has multiple benefits: improvement of microcirculation, increased local metabolism and lipolytic action (fat burning) at the level of fatty tissue.
All this, and especially the better circulation, causes the draining effect that we seek in the case of 'fluid retention' or poor circulation.
