A couple of years ago rejuvenation by laser was an elusive dream, which seemed like a magic procedure. Today to look younger than their years can everyone. Planning to carry out this procedure, it is necessary to study the characteristics of the laser method of rejuvenation that will help you make the right decision.
Before you go to a specialist, you should know that there are two types of laser resurfacing, in particular:
- non-ablative laser treatment;
- ablative laser treatment.
Each of them is:
- sheet (complete);
- incomplete (fractional).
Both methods share a common feature – if the laser procedure is done correctly, the skin becomes fresh and "takes several years".
During this procedure, the skin is heated by the laser beam, and the laser affects the deeper layers of the skin, the cells that produce fibers (fibroblasts). The laser causes the cells to carry out the micro-circulation in certain layers of the skin more actively. To use this method in the presence of post-acne, scars, ptosis, sagging of the skin.
For resurfacing the erbium laser is used, which when exposed to the skin is not "touching" the top layer of the skin as the wavelength is 1550 nm. After the intervention of the skin, which was carried out in influence, becomes shiny, soft. If the skin is wrinkled, the face has uneven color, pigmentation, stretch marks, acne, etc., then, this method helps to quickly remedy the situation. A method of exposure based on the exposure to the laser beam, that due to long waves has no effect on the upper layers of the skin and stimulates the cells of the dermis.
The main difference between ablative method described above is that the laser exposure is performed in all layers of the skin, including the top, and the procedure that uses the laser of carbon dioxide (CO2). This method is recommended and is most often used to remove small facial wrinkles, the wrinkles that form around the eyes, to get rid of the pigmentation, to improve the tone of the skin. The procedure consists of a powerful effect on the dermis, which favors smoothing the texture of the skin and has a marked lifting effect. The wavelength of the laser used in this method is 10600 nm.
The principle of the ablative method is the impact on the water in all the layers of the skin with a laser beam.
After the intervention, the rehabilitation period will be higher than if the conduct of non-ablative resurfacing, which involves the effects on the deeper layers of the skin. In both cases, the laser affects the water molecules that reside in the skin, and the liquid "falls" of the dermis by means of evaporation, followed by the synthesis of collagen and elastin, which are necessary for the rejuvenation of the skin.
The intensity of the exposure of each of the methods depends on the current condition of the skin and the desired result. In addition, the choice of a suitable method of laser resurfacing can be a doctor, that in this direction we have adapted the qualification and great experience.
Differences of continuous laser treatment and fractional impact
In order to obtain complete rejuvenation, it is necessary to use a laser beam, which affects the skin a "solid point". The method involves the continuous grinding of the epidermis, and so, little by little damaged cells are replaced by new ones. Fractional impact replacing the leather processing, solid (full) method, which is understandable. We are talking about the fact that after laser treatment the skin is restored for a long period of time in addition, the formation of scars on the surface of the skin.
Fractional of the exhibition is based on the principle of the skin to the exposure of the area, that is to say, the beam falls on the skin is not "solid point", which, forming a small grid. This means that the impact on the small portion of skin and not on the entire surface. In particular, the beam can cover an area about 20% of the entire face, but the rejuvenation affects the whole face, in spite of the zonal division of radiation exposure.
Photorejuvenation laser
Photorejuvenation is an improvement of the shape of the effects, which are not affected by the upper layers of the epidermis. Therefore, this technique has a lot of differences with the usual method. Photorejuvenation treats age spots, vascular pathologies, corrects the appearance of photodamage. This exposure rays are used, the length of which depends on the type of device used in the procedure in particular.
Thus, when the radiation is "ignorant" of the water, that is to say, the beam does not interact with the fluid, but absorbs the hemoglobin and melanin, which makes the photorejuvenation procedure as efficient as possible, especially when problems with the blood vessels and pigmentation. Photorejuvenation causes the start of the production of collagen, which tightens the skin, smoothes wrinkles, improves color of the skin and improves its tone.
After the intervention, the rehabilitation period is not needed, and the procedure is performed without anesthesia. Unscrupulous "experts" do not tell the customers about the methods of laser resurfacing, thus "forcing" to use available at this time. The result of this process may not be expected or even a negative result, this means that, deciding to rejuvenate, you should only go to experienced doctors with high capacities.
