As with many other health and beauty treatments, there are varying opinions on the effectiveness of carboxytherapy. People have recognized the health benefits of bathing in spring water with carbon dioxide for decades, and it is thought to be effective in treating some vascular diseases, high blood pressure and heart disease. Some scientific studies have shown that carbon dioxide can have a positive effect on the human body. For example, one study found that such bathing improved blood flow through the areas of the body that were immersed in the water [source: Ito].
However, some experts question whether enough scientific evidence exists to prove carboxytherapy's effectiveness in treating cellulite or scar tissue. Carboxytherapy practitioners disagree, saying that the treatment can trick the body into increasing blood flow. They argue that the procedure is much less invasive than liposuction, with similar results [source: CarboxyWorld]. Practitioners of carboxytherapy can see the effects and results up close -- and many claim it works wonders -- but without extensive, long-term studies, the jury is still out on this one.
If you choose this treatment, you should notice improvement after your first time, but you will likely require multiple treatments to achieve maximum results [source: McDonald]. Since cellulite can return, you might need additional treatments several times per year.
Multiple treatments, however, can mean high bills. For more about the cost of carboxytherapy, read on.
