CO2 (carbon dioxide) and erbium lasers are used for rejuvenation, the radiation of which is mainly absorbed by water. They differ from each other in terms of wavelength and the degree of energy absorption, which determines the technology of the process. CO-2 devices are used for abstract rejuvenation and erbium devices - for non-abstract.
With abstract rejuvenation, the laser beam acts not only on the deep layers of the skin, but also on the surface. With non-removable - the laser penetrates deep into the tissue, but does not damage the surface of the skin. This is possible due to the different wavelengths of lasers, as well as the fact that the skin contains less water (10-15%) than in the deeper layers of the skin (70-75%).
Carbon dioxide lasers have the longest wavelength of any medical laser available at 10, 600 nm. Such rays are very well absorbed by water, so they react even with the small amount of water contained in the skin. Therefore, removal techniques are performed with the help of such lasers, capable of affecting the surface layer of the skin.
Erbium laser wavelengths range from 1064 to 2940 nm. Clinics use the Palomar Lux 1540 laser, which has a wavelength of 1540 nm and a depth of tissue penetration of up to 2 mm. Such rays are absorbed less by water and therefore pass through the skin without damaging it. The action of the laser already begins in deep layers, where there are enough water molecules to interact with the beam. Palomar Lux 1540 is used for fractional photothermolysis.
Why is laser rejuvenation a safe and effective procedure?
Modern CO2 and erbium lasers act fractionally, ie the beam is subdivided into small beams in the form of a grid. Because of this, only 20% of the surface is damaged and the recovery process begins throughout the skin volume. This effect minimizes the possibility of heat damage, unpleasant consequences in the form of scars and scars and also increases the rate of tissue repair.
As a result of the laser action, a coagulation column is formed, in the case of abstract technology - open, non-abstract - closed. These columns are at a certain distance from each other due to fractional action. The cells around the coagulation zone undergo heat shock, which activates metabolic processes and the production of new cells. Thanks to this, an lifting effect is achieved, the skin is rejuvenated.
To whom is abstract rejuvenation suitable?
Abstract rejuvenation is an extremely effective method for solving problems such as shallow wrinkles, pigmentation and reduction of skin elasticity and firmness.
The laser works mainly on the upper layers of the skin, does not penetrate deeply, but affects the surface layer. Thanks to this, the skin is renewed to the full depth of penetration of the beam (up to 1 mm) and the obvious correction of surface imperfections. To achieve a good result, only 1 procedure is required. The recovery period after the procedure is 5-7 days.
Remedial rejuvenation, especially DOT treatment, is suitable for those who want to have a quick result with a minimal recovery period.
To whom is non-abstract rejuvenation suitable?
Non-removable rejuvenation is also one of the most effective techniques for eliminating wrinkles, skin rejuvenation, rejuvenation, improving skin quality, treating pigmentation and other skin imperfections.
The operation of the laser only in the deep layers leads to the fact that the recovery period after the procedure is practically absent and is only 2-3 days. Achieving an effect similar to abstract rejuvenation will require a larger number of procedures, usually 3-4. Due to the deeper penetration, a complete restructuring of the tissues occurs, which gives a remarkable lifting effect.
Non-abstract rejuvenation, especially fractional photothermolysis, is suitable for those who want to have a remarkable result without intensive exposure and recovery period.
