The color of the human skin depends on a substance such as melanin. As a rule, as the body ages, its balance in the body is disrupted and pigment spots of different shapes and sizes, usually brown in color, appear on the skin. Most often this is observed in women. At them it usually occurs because of a wrong metabolism, bad cosmetics, at some diseases, especially chronic, long stay on the sun, pregnancy and hormonal failures.
To reduce the staining spots there are quite a lot of drugs, mostly in the form of creams, as well as other methods of treatment: surgitron, dermabrasion, Fraxel, phototherapy (photorejuvenation). Both pigment spots and other skin defects can be easily removed with the help of the above procedures.
Phototherapy (or as it is often called, photorejuvenation) is the bombardment of skin areas with light beams of a certain length, 500-1200 nm. Melanin absorbs this light, which leads to its disintegration, and this disintegration does not affect the rest of the body. In this case, the proteins in this place coagulate, which can lead to a temporary darkening of the spot. However, after a few days the stain disappears, and in its place a new clean skin appears. Thus, with this method of treatment, there is no correction of skin color, and stains are eliminated completely.
How is the procedure for photorejuvenation?
On the area with pigment spots, which are going to be processed, a contact gel is applied, if necessary, glasses with darkened glasses are put on the eyes. Then a special IPL-tip is exposed to radiation on the right parts of the skin, almost immediately warming them up and not affecting the rest of the body.
In the pigmented spots on the skin, proteins begin to coagulate, the removal of diseased cells - those that contain too many pigments, pathological collagen and melanin. Cells are destroyed very quickly, on average, the time for which the cell is destroyed is about 0.001 seconds. Then the body removes these cells from tissues, and in return creates new, healthy ones.
The course and duration of the procedure for photorejuvenation
The time for which the phototherapy procedure is performed can vary from a few minutes to 1-2 hours. It depends on the number of problem areas of the skin, their location and size. After the procedure, the first few hours the skin in these areas can be reddened, then it passes. To fix the effect of photorejuvenation by doctors, it is recommended to avoid exposure to sunlight for the first two weeks and not to take water procedures for 3-4 days. If all the recommendations are followed correctly, the skin becomes firm and dense, a natural healthy color.
To remove wrinkles and prevent skin aging, it is often necessary to conduct a whole course of treatment, but it's worth it - the skin will look young and healthy. Very effective phototherapy in the so-called photoaging, when the skin suffers from the excess of ultraviolet radiation.
Photorejuvenation activates the processes of renewal in the skin, stimulates its recovery, the synthesis of nutrients, which in turn, begins to have a beneficial effect on the appearance - the skin is tightened.
Typically, the course consists of 2-7 steps, the interval between which is about 3-4 weeks. At the same time the skin condition gradually becomes better and better, which is easy to see by its appearance - the skin is smoothed, the number of vascular asterisks and various spots decreases. By the third and fourth session pores begin to narrow and wrinkles disappear noticeably. If the patient goes through a full course, it can be guaranteed that his skin will remain in excellent condition for a long time.
The time and intensity of radiation in the treatment of the skin varies depending on the characteristics of the patient's body, as well as on its nuances of pigmentation.
Contraindications for the procedure of photorejuvenation
This technique has contraindications. The procedure can not be carried out with the recently obtained tan and with increased photosensitivity (it is rare). It is not recommended to conduct phototherapy in case of viral infections, pregnancy, skin diseases and diabetes mellitus in acute form.
