Fractional photothermolysis is a procedure whose action is aimed at correcting the skin with a laser beam. The method is very effective, but traumatic and requires a rehabilitation period. Thermolysis is the destruction of cell structure by a thermal stimulus, and photothermolysis does the same thing, only with the help of light energy.
A laser beam directed into the thickness of the skin (in the form of a thermal column) forms a controlled burn, thereby removing unnecessary skin defects. There are two methods of photothermolysis, differing from each other in the degree of impact on the skin.
Ablative photothermolysis
This method is based on the fact that a certain laser beam is absorbed, mainly by water molecules. The water contained in the tissues is heated up to 300 degrees Celsius and evaporates within the laser column. In this place, an open wound is formed.
Of course, the rehabilitation process after such a procedure is quite long - at least seven days, but the effect is very noticeable. After wound healing, the skin is noticeably tightened and evened out. It doesn't have to be done just once. The course depends on the complexity of the problem and ranges from 2 to 6 times. It is worth remembering that there is a risk of infection of the skin.
Non-ablative photothermolysis
This procedure is less traumatic, as it is carried out inside the skin without damaging the outer layer of the epidermis. Tissues are not destroyed within the entire laser beam, and all processes occur inside the skin layer. The tightening effect, with this method, is less pronounced than with the ablation method, since the destruction products remain in the thickness of the skin and are not brought out.
On the positive side, there is no risk of skin infection and the rehabilitation process is quite short - only 2-4 days. To obtain a good result, it is necessary to carry out from 3 to 10 procedures.

- Presence of pigmentation
- The presence of stretch marks.
Contraindications
- Oncological diseases
- lactation period
- Presence of infectious diseases
- Diabetes
- Autoimmune diseases
- Deviations of the psyche
- Recent sun exposure (tanning) or tanning beds
Possible side effects
- Infection of wounds
- Active pigmentation after the recovery period
- Microhemorrhages in the subcutaneous layer
- The occurrence of burn blisters and cracks in the skin.
Fractional laser rejuvenation of Kodi is carried out using special devices in specialized institutions. Depending on which procedure is needed, different types of laser are used.
For example, in order to remove a scar, you need a laser that can penetrate into the deeper layers of the skin (CO2 laser). And to remove pigmented spots (freckles, for example, or postpartum pigmentation on the skin) are removed with an erbium laser. In order to get facial rejuvenation with a good lasting effect, ideally you need to use several types of lasers.
It is worth paying special attention to the professionalism of the cosmetologist who will carry out the procedure. Do not be shy and check the certificates for the right to conduct photothermolysis, indicating that the specialist is trained and has a certain skill and qualification. And, of course, the most correct option would be if the procedure is performed by a dermatologist-cosmetologist, that is, a specialist with a higher education who has been working in a clinic or beauty institute for more than one year.
