Fractional photothermolysis occupies a special place among the various methods of non-surgical skin rejuvenation. This is due to the fact that this procedure allows you to obtain good results due to the special effect of the laser beam on the skin of the face and body.
In addition, the fractional rejuvenation procedure is characterized by absolute safety and comfort with very high efficiency. That is why today almost 70% of all patients who decide to renew the skin without surgery resort to it. However, before delving into the essence of laser skin rejuvenation, let's talk about the reasons for its aging.
It is with the skin that the natural aging process begins in the body. Performing the most important protective functions, the skin constantly encounters aggressive environmental factors, systematically receiving less nutrients from the body for proper functioning.
As a result, a certain imbalance of water and nutrients occurs at the cellular level, as a result of which metabolic processes slow down in cells and the rate of renewal of the cellular composition of the epidermis is significantly reduced.
Accordingly, the skin, losing its natural firmness and elasticity, eventually becomes flabby and dry, which causes the appearance of wrinkles and age spots on the face and body. Fortunately, you can get rid of the first signs of aging quickly enough.
Laser and, in particular, fractional, skin rejuvenation is advisable to carry out at the age of 35 to 50 years. During this period, the aging process in the skin has already begun, but the body still has enough strength to restore and renew cells.
Unlike other laser rejuvenation procedures, fractional photothermolysis is based on the formation of so-called microthermal healing zones in the skin. That is, not all skin is exposed to the laser, but only its microscopic areas. This effect is achieved due to the fact that in the process of supplying energy, the laser beam acquires a mesh structure, being divided by the laser apparatus into thousands of microbeams.
Accordingly, the main skin remodeling processes take place precisely in the microthermal zones formed by the laser beam.
I must say, fractional skin rejuvenation can be of two types:
In an ablative procedure, the top layer of skin in microthermal zones is vaporized with a laser beam. Thus, microtrauma is applied to the skin, which activates the process of intensive healing in the skin and, as a result, the formation of renewed cellular structures.
In this case, the skin areas not affected by the laser beam are also involved in the renewal process.
With non-ablative intervention, the integrity of the skin is not disturbed, and the micro-rays penetrate directly into the deep layers of the skin, where they act on the principle of laser heating, stimulating fibroblasts to produce collagen and cell division at the level of the dermis, that is, in the deep layers of the skin.
Fractional photothermolysis, as a rule, gives a predictable result, noticeable after the first procedure. After completing the course of procedures, the following happens:
At the same time, age-related pigmentation disappears, the skin acquires its characteristic firmness and elasticity.
The main advantage of fractional photothermolysis over non-laser rejuvenation procedures is the increasing long-term effect. Six months after the last procedure, the renewal of the cellular composition of the skin will be completely completed, that is, after six months it will be possible to specifically judge the result. In this case, the effect will last from 5 to 7 years, and subsequently it will be enough to undergo one preventive procedure per year to maintain the natural youth of the skin.
