Benefits of a CO2 Laser

Modern aesthetic medicine is an area that can no longer exist without laser technology. They are in many cases the most effective treatment. For laser skin rejuvenation and facial debridement, a carbon dioxide CO2 laser was used for the first time (more than 40 years ago). The CO2 laser is used in dermatological surgery. Taking into account that the system of carbon dioxide laser delivery of non-continuous radiation and newer “super-pulsed” and scanned carbon dioxide systems have gradually changed our practice and patient satisfaction, the information accumulated over many years can be useful.

Our experience has shown that the use of a carbon dioxide laser includes a reduction in treatment time, a rare need for anesthesia, a reduction in the number of thermal trauma, a reduction in bleeding, a decrease in inflammation, the possibility of intraoperative histological and/or cytological examination, and easy access to anatomically inaccessible places. The immediate side effects of pain, redness, and swelling, as a rule, are manifested by using older methods using higher power.

The laser is based on the conversion of the energy of laser radiation into thermal radiation [72, 73]. The interaction of electromagnetic radiation from a laser source and biological tissues is determined by physical processes that regulate the energy exchange between the wave and the substrate, as well as the biological reaction of the target tissue. Depending on the temperature achieved in a particular area, the thermal energy produced can coagulate, evaporate, or degrade. At a sufficiently high energy density (above the minimum ablation threshold), heat is used mainly for the destruction or evaporation of the target tissue, before the slower spread to the surrounding areas begins.

The carbon dioxide laser operates at a wavelength of 10,600 nm in the far infrared region of the spectrum, where the chromophore absorption of intracellular and extracellular water molecules predominates.

Carbon dioxide laser is one of the types of “contactless surgery” belonging to the group of lasers in the category “WYSIWYG” (what you see is what you get).

According to this information, we can sum up and talk about some benefits of a CO2 Laser at Laser Agent.

In fact, these laser systems allow accurate, effective and targeted thermal effects on the lesions to be treated while protecting adjacent areas, thus ensuring optimum re-epithelialization. This makes the laser suitable for surgical procedures since a limited inflammatory response promotes better healing. High accuracy of application means that only the epidermis can be evaporated, or the heat effect can be spread even deeper into the papillary or reticular dermis.

The benefits of a carbon dioxide laser include a reduction in healing time, a rare need for anesthesia, lower thermal loss, less bleeding, less inflammation, and minimal unwanted side effects (anesthetic
scars and dyschromia effects). These advantages should be considered in comparison with other available surgical methods, such as diathermocoagulation and traditional surgery, which, on the contrary, necessitate the frequent use of anesthetic, a longer rehabilitation period, slower scarring, and a high incidence of hypertrophic and keloid scars.
