CO2 (carbon dioxide) and erbium lasers are used for rejuvenation, and the radiation is mainly absorbed by water. Their wavelength and energy absorption are different, which determines the technique of surgery. The CO-2 equipment is used for ablative rejuvenation, and the erbium equipment is used for non-ablation.
By burning the skin, the laser beam not only acts on the deep layer of the skin, but also on the surface layer. Non-ablative-the laser penetrates deep into the tissue, but does not damage the surface of the skin. This is possible because the wavelength of the laser is different and the water content of the epidermis (10-15%) is less than that of the deeper layers of the skin (70-75%).
The longest wavelength of carbon dioxide laser is 10, 600 nm. Such rays are easily absorbed by water, so even if there is a small amount of water in the epidermis, they will react. Therefore, the ablation technique with the help of this laser can affect the surface layer of the skin.
The wavelength range of erbium laser is 1064 to 2940 nm. The clinic uses Palomar Lux 1540 laser, which has a wavelength of 1540 nanometers and can penetrate tissues to a depth of up to 2 mm. This kind of rays are less absorbed by water, so they can pass through the epidermis without damaging it. The laser action has already started at a deep level, where there are enough water molecules to interact with the beam. Palomar Lux 1540 is used for partial photothermal decomposition.
Why is laser skin rejuvenation a safe and effective surgery?
The effect of modern CO2 and erbium lasers is very small, that is, the beam is subdivided into microbeams in the form of a grid. Therefore, only 20% of the surface is damaged, and the entire skin volume is starting the recovery process. This effect minimizes the possibility of thermal damage, reduces unpleasant consequences in the form of scars and scars, and increases the speed of tissue repair.
As a result of the laser action, in the case of the ablation technique the solidification column is formed-open, non-ablative-closed. Because of the score, these columns are at a distance from each other. The cells around the coagulation zone experience heat shock, which activates metabolic processes and the production of new cells. Due to this, a lifting effect is achieved and the skin is rejuvenated.
Who is suitable for ablation rejuvenation?
Ablation skin rejuvenation is an efficient way to solve the problems of shallow wrinkles, pigmentation, skin elasticity and firmness.
The laser mainly acts on the upper layer of the dermis and will not penetrate deeply, but it will affect the surface layer. Due to this, the skin is updated to the full penetration depth of the beam (up to 1 mm) and surface defects are clearly corrected. To achieve good results, only one process is required. The recovery period after surgery is 5-7 days.
Ablation rejuvenation, especially DOT therapy, is suitable for people who want to get quick results with the shortest recovery period.
Who is suitable for non-exfoliative skin rejuvenation?
Non-exfoliative skin rejuvenation is also one of the most effective techniques to eliminate wrinkles, enhance skin, rejuvenate, improve skin texture, and treat pigmentation and other skin blemishes.
The laser is only used in the deep operation and the recovery period after the operation is practically non-existent, only 2-3 days. In order to achieve an effect similar to ablation rejuvenation, more operations are required, usually 3-4 times. Due to the deeper penetration, the organization will undergo a complete reorganization, resulting in a significant improvement effect.
Non-exfoliative skin rejuvenation, especially dot-matrix photothermal therapy, is suitable for people who want to achieve significant results without intensive exposure and rehabilitation.
