It has been 58 years since the first CO2 laser was born. It is a veteran in the field of optoelectronics. Today, the equipment of the machine has made great progress in terms of technology and clinical, and the effect of CO2 laser It has been recognized by everyone over the years.
Nowadays, both private beauty institutions and dermatology, cosmetology and other related departments in public hospitals are basically equipped with CO2 laser equipment, so CO2 laser is a very popular laser project.
The principle of CO2 laser
As long as we talk about lasers, we have to take out this treasure map, because this is the theoretical cornerstone of all laser equipment;
10600 is the wavelength of CO2 laser, which has never changed, only the light output mode, power, pulse width and other technical performance parameters;
Therefore, the effect of CO2 laser on tissue is the effect on water.
The main principle is broken down into three parts:
1. Exfoliation and reconstruction of the epidermis
When the CO2 laser energy density and pulse width reach a certain value, a CO2 laser pulse can peel and vaporize 20um thick skin tissue;
2. Stimulate collagen regeneration
If the laser is emitted in the scanning lattice mode, a burning area composed of laser action lattices and intervals will be formed in the epidermis, and the laser can directly penetrate into the dermis at each point. The epidermal tissue is directly vaporized, thereby stimulating the production of collagen, which further initiates a series of biological reactions such as the repair of the dermal tissue and the rearrangement of collagen.
3. Causes collagen fibers to shrink
Collagen fibers also shrink by about one-third under the action of the laser, thereby achieving a firming effect.
Application of CO2 Laser
Due to the early launch of CO2 laser, the current application of CO2 laser is not only limited to medical beauty, for example, surgery and ophthalmology are routine treatments; here we only introduce its application in the field of skin beauty.
In the field of medical aesthetics, CO2 laser is widely used in dermatology as a laser full-thickness epidermis reconstruction. Before the application of dot matrix technology, CO2 laser was used as a laser full-thickness epidermis reconstruction, that is, full face skin resurfacing.
