For renewal, CO2 (carbon dioxide) and erbium lasers are used, their radiation is mostly absorbed by water. They differ from each other in wavelength and energy absorption, which determines the technology of the method. CO-2 devices are used to renew destruction, and erbium devices - not to destroy.
With ablative regeneration, the laser beam acts not only on the deep layers of the skin, but also on the surface layers. With non-ablative - 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 the lasers, in addition to which the epidermis contains less water (10-15%) than in the deep layers of the skin (70-75%).
Carbon dioxide lasers have the longest wavelength of any medical laser beam available at 10, 600 nm. Such rays are very well absorbed by water, so they respond even with a small amount of water that is in the epidermis. Therefore, removal procedures are performed with the help of such laser beams, which can affect the surface layer of the skin.
Erbium laser wavelengths range from 1064 to 2940 nm. The clinics use Palomar Lux 1540 laser, its wavelength is 1540 nm, and the depth into the tissue is up to 2 mm. Such rays are less absorbed by water and pass through the epidermis without damaging it. Laser activity begins immediately in deep layers, where there are enough water molecules to interact with the beam. Palomar Lux 1540 is used for refractive index temperature analysis.
Why is laser renewal a safe and effective method?
Modern CO2 and erbium laser function in fractions, e. g. e. the beam is divided into a micro-beam in the form of a grating. As a result, only 20% of the surface is damaged and the healing process begins over the entire volume of the skin. This effect minimizes the possibility of heat damage, unpleasant consequences in the form of scars and scars and also increases the speed of tissue repair.
As a result of the laser action, coagulation columns are formed in the case of ablative technology - open, not ablative - closed. These columns are located at a certain distance from each other due to breaking activity. The cells around the coagulation region are exposed to heat shock, which activates the metabolic process and the formation of new cells. Thanks to this next lifting effect, the skin is rejuvenated.
Who is suitable for renewal with dropout?
Ablative rejuvenation is a very effective method to solve problems such as shallow wrinkles, pigmentation and reduction of the elasticity and firmness of the skin.
The laser works mainly in the upper layers of the dermis, does not penetrate deep but affects the surface layer. Thanks to this, the skin is renewed to the full depth of the penetration of the beam (up to 1 mm) and an obvious correction of superficial imperfections. To be successful you only need 1 method. Post-surgery recovery time is 5-7 days.
Ablative cleansing, especially DOT treatment, is suitable for those who want to achieve quick results with a minimum rehabilitation time.
Who is suitable for renewal without abolition?
Non-removal rejuvenation is also one of the most effective methods to eliminate wrinkles, lift skin, rejuvenate, improve skin quality, treat pigmentation and other skin imperfections.
The operation of the solvent only in the deep layers means that the rehabilitation period after the operation is almost absent and is only 2-3 days. To achieve a similar result and renewal with deletion, more operations are needed, usually 3-4. Due to the deeper penetration, a complete tissue restructuring takes place, which gives a noticeable lifting effect.
Indelible renewal, especially refractive index temperature analysis, is suitable for those who want to achieve noticeable results without much exposure and rehabilitation time.
