Its use allows to stimulate the oxygenation of the dermis all over the face and neck. It is also used with benefit in the area under the eyelids.
The principle of operation is very simple and starts from the assumption that carbon dioxide (CO2) is for our body a waste to be eliminated.
As a waste product of the cellular metabolism, carbon dioxide is exchanged with oxygen and transported by red blood cells to the lungs to be expelled with breathing. When a red blood cell encounters carbon dioxide, it releases the oxygen molecules it carries to load the latter, with which it has much more affinity.
Carboxytherapy determines a local CO2 accumulation that results in reactive hyperoxygenation (for red blood cell oxygen release, which must transport it to the lungs). This hyperoxygenation improves the vitality of the treated tissues, session after session.
It therefore improves skin tone and reduces the bluish colour that is sometimes present in the lower eyelids. All of these effects are secondary to the beneficial effects that carboxytherapy exerts on microcirculation.
