The laser light is absorbed by a particular chromophore, for a CO2 laser them is water. During the procedure, its evaporation, mainly of the surface layers of the skin. But the doctor can visually control the amount of tissue removed: the entire surface looks the same after treatment - dark-brown color. Therefore, the doctor without the proper experience can easily coagulate the epidermis and reach the papillary dermis. The result is a whole spectrum of complications at best skin becomes inhomogeneous, and in the worst - formed scarring and fibrosis portions if the surface exposure was extensive. The laser energy is strongly scattered, thereby reducing the effectiveness of the procedure.
To compensate for the loss, it is necessary to increase the flow rate, which causes severe burns tissue and, as a consequence, the development of side effects such as skin atrophy or pigmentation. In addition, the procedure can not be carried out in areas with thinner skin, such as neck and neck, as the skin in these areas was not restored as the face, and it was obvious where the patient is doing the procedure and where - no. All of the above and a long period of rehabilitation after the procedure (in the hospital the patient should stay a few days and then home for 2-4 weeks) forced producers to seek new methods.
Fractional Ablation or ablative fractional photothermolysis - It is of micro-vaporization of the skin (more than the deep layers) by a laser beam with subsequent compression and decompression of the microregions. As for the traditional laser resurfacing usually used for fractional CO2 lasers, in which the integrated optical element, breaking the laser beam at microbeams.
But unlike conventional CO2 lasers removing all layers of the skin surface, there is formed a huge amount mikroablatsionnyh zones. Fractional principle can influence the skin much deeper than the Laser resurfacing . In the dermis there are numerous mikrokrovopodteki (since there is a rupture of the blood vessels), which induces a complex cascade of changes leading to the production of new collagen. As a result, the procedure removes excess skin, the surface is leveled, the porosity decreases. To prevent scarring and post-inflammatory pigmentation manifestations must be carefully care for the skin.
Also, manufacturers recommend the use of sunscreen cosmetics after the procedure with a high degree of protection (SPF at least 50) for at least 3 months. Great risk of unwanted pigmentation and people with IV-V skin phototype. To prevent it 1-2 weeks before the procedure and for a further 2 weeks after it appointed a special external agents. Due to strong vaporization of tissue is dehydration (drying) of the skin may appear small wrinkles. Unable to get rid of the pain - before and after the procedure, patients are advised to take painkillers and put a special anesthetic cream or half an hour before the procedure.
Matrix RF applicator based on the action of bipolar RF-waves (radio-frequency) . Bipolar impact means that current flows between the positive and negative electrodes, forming a closed circuit RF-energy penetrates the epidermis into deeper layers of the dermis . Changing the energy density along the path along which the wave propagates, it leads to effects that are not only at different depths, but also in the space between the electrodes . Due to the fact that the resistance of the stratum corneum of dry higher RF energy passes through the electrodes themselves (as with monopolar effects), causing, primarily ablation . In deeper layers of tissue (the lower layer of the epidermis and dermis), the resistance is lower because the fabric is saturated with water and electrolytes . Therefore, here RF-energy takes place between the electrodes (as in bipolar radio frequency exposure), creating a wider effect in the form of disseminated coagulation / necrosis with little tissue ablation . With this procedure, a tiny plots epidermis and dermis undergo thermal ablation / coagulation in evenly spaced points .
The combination of protein coagulation in the depths of the dermis, triggering neocollagenesis and ablation (evaporation skin layer) for maximum aesthetic effect.
The high-frequency current hardly affects the surrounding tissue without causing significant burns, coagulation is performed without tissue destruction. Since there is no injury, healing is no postoperative pain and no scarring. Also, a significant advantage of the method is the high frequency sterilizing effect, whereby the risk of subsequent infection is minimized. When a bipolar current is able to control the depth of penetration and the amount of energy supplied, as it is no loss due to scattering or reflection.
Extensive device (there are three programs) allow, considering the individual characteristics of each patient, increase the effectiveness of treatment. The procedure goes with minimal discomfort and requires no anesthetic. Recovery is very quick, and the treatment itself does not require much time, because sometimes enough even one session.
As a result, the procedure takes wrinkles by reducing the amount of skin, sealing it by affecting the connective tissue bands, there is a reduction of pore sizes. The procedure is suitable for the treatment of post-acne, stretch marks removal, correction of scars. This method is used in areas with thin skin - eyes, neck, décolleté. Suitable for people with any skin phototype.
