CO2 laser is a molecular laser with the main substance being carbon dioxide molecules. The specific wavelength of this laser is 10.6um, which is almost 100% absorbed by the human body (irrespective of the skin color). The laser can slightly penetrate the skin, and the beam is a highly concentrated and powerful beam that can be accurately applied to areas with a diameter less than one millimeter without affecting the surrounding tissue.

Yes, it is safe, but it is not suitable for everyone. Some people may be more sensitive to laser use, so before using CO2 laser, it is recommended to consult a cosmetologist to assess whether it can be applied.
