For rejuvenation, CO2 (carbon dioxide) and erbium lasers are used, the radiation of which is mainly absorbed by water. They differ from each other in wavelength and degree of energy absorption, which depends on the technology of the procedureDetermines. CO-2 devices are used for ablative rejuvenation, and erbium ones - for non-ablative.
With ablative rejuvenation, the laser beam acts not only on the deeper layers of the skin, but also on the superficial 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 lasers as well as the fact that the epidermis contains less water (10-15%) than 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 also react with small amounts of water contained in the epidermis. Therefore, ablative 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 penetration into tissues up to 2 mm. Such rays are less absorbed by water and thereforepass through the epidermis without damaging it. The laser action begins already in the deeper 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 work partially, ie. The beam is divided into micro-beams in the form of a grid. Due to this, only 20% of the surface is damaged, and the entire volume of the skin is retrievalThis effect reduces the likelihood of unpleasant consequences in the form of heat loss, scars and scars, and also increases the rate of tissue repair.
As a result of laser action, a coagulation column is formed in the case of ablative technology - open, non-ablative - closed. Passes, which activate metabolic processes and the production of new cells. Thanks to this, a lifting effect is achieved, the skin is rejuvenated.
Who is Ablative Rejuvenation suitable for?
Ablative rejuvenation is a highly effective method to address problems such as shallow wrinkles, pigmentation and loss of skin elasticity and firmness.
The laser works mainly in the upper layers of the dermis, does not penetrate deeply, but affects the surface layer. Thanks to this, the full depth of penetration of the beam (up to 1 mm) and the apparent correction of superficial imperfections is achieved. To get a good effect, only 1 procedure is needed. The recovery period after the procedure is 5-7 days.
Ablative rejuvenation, especially DOT therapy, is suitable for those who want to achieve quick results with minimal rehabilitation period.
Who is non-ablative rejuvenation suitable for?
Non-ablative rejuvenation is also one of the most effective techniques to eliminate wrinkles, plump up, rejuvenate, improve skin quality, treat pigmentation and other skin imperfections.
The operation of the laser only in the deep layers leads to the fact that the rehabilitation period after the procedure is practically absent and is only 2-3 days. To achieve a result similar to ablative rejuvenation, a large number of procedures will be required, Usually 3-4. Due to the deep penetration, there is a complete restructuring of the tissues, which gives a noticeable lifting effect.
Non-ablative rejuvenation, in particular fractional photothermolysis, is suitable for those who wish to achieve noticeable results without intense exposure and rehabilitation periods.
