Non-Invasive Carboxytherapy facial is a treatment during which a gas, carbon dioxide (CO2), is infused into the skin to encourage an increased flow of oxygen. 

What Carboxytherapy does is trick your body into thinking that there is an oxygen deficiency in the area. The body then responds by improving blood flow and widening the blood vessels, which leads to an increased oxygen supply. This helps restore the cells, improving skin elasticity and overall appearance.
