Carboxy

Carboxy therapy is the administration of carbon dioxide [CO2] gas for healing purposes.

The major cause of dark circles under the eye is vascular pooling. Carboxy therapy works to improve the blood flow of the lower eyelids, as well as increase the collagen layer. By injecting a small amount of CO2 gas into the affected areas, the flow of blood is increased causing the bluish color to be replaced with a healthy pink tone.
