Dynamic Oxygen Slimming Arm is to use Polar Dynamic Oxygen Radiofrequency Therapeutic Instrument, through the wave effect of gasification fat reduction, resulting in the body of the local carbon dioxide concentration increases, so that the part of the hypoxia, to promote the release of more oxygen hemoglobin, thus promoting blood circulation, accelerating the decomposition of fat combustion, combustion of the accumulation of hard fat, disintegration of cellulite, so that the skin is smoother for the upper arm fat increase or deposition, affecting the curve of the body shape people.
