In modern dermatology and cosmetology, a large number of methods for correcting age was developed in view of the face. Field laser tendencies is one of the non -repressed methods to combat aging. Sparing technologies for laser corrections are becoming increasingly popular due to their technical simplicity and short recovery phase.
The operating principle of the fracture laser
In contrast to the classic laser loops, in which the entire surface layer of the skin is evaporated, the fractional laser works punctually.The rejuvenation of tissues is associated with the phenomenon of hormesis - the stimulation of recovery processes under the influence of stress, the strength of which is not sufficient to recognize harmful consequences.In this case, a laser beam that leads to tissue heating to 45–90 ° C acts, since the contact time of the light beam with the skin acts as a voltage factor (up to 0, 0003 ° C), the temperature increase in a small range of 100 micrometers. Heat is not transferred to the surrounding tissue.
Distinguish 2 main types from fractional
After processing the tissue, an inflammatory process occurs with a laser beam, but the stingy skin layer remains intact. Thermal stress stimulates the production of special biologically active proteins and the activation of cellular activity that aims at survival. In healthy tissues that surround the heating range, the intensive production of collagen and elastin is started, metabolic processes are improved. As a result, the skin becomes smooth, more elastic, the moisture content increases.
The hormal process was examined at increased ambient temperatures at Volat-Fructus Volat. For people who survived with thermal stress, life expectancy was higher than with insects in the control group that were contained under normal conditions. Perhaps the production of heat shock proteins and wellness procedures such as bath, sauna and hardening in ice water are also connected.
The duration of the rehabilitation period with fractional laser rejuvenation is reduced because the skin damage is small -specific and not continuous. The surface under thermal exposure is about 20%. Dead cells, melanin pigment and other metabolic products are partially absorbed by macrophages that strive to penetrate the inflammatory zone. The rest of these substances are replaced by the surface of the skin 3-7 days after laser processing. After 4 to 14 days, a complete restoration of tissues occurs.
Indications for use
Field laser rejuvenation of a person is used in the following cases:
- Elimination of signs of skin aging:
- Acceptance of elasticity;
- Extended pores;
- Unequal color.
- The smoothing of static and facial folds, including delicate areas near the eyes, on the eyelids to the eyelashes.
- Treatment of melasms, pigment spots (liver, sunny, age, hormonal).
- Correction of scars, postoperative scars, uneven texture.
- Treatment of skin defects that are a sequence of acne.
Technology of fractional laser rejuvenation of the face
In modern cosmetology, 2 methods are used that fundamentally differ on the skin in the method of influence:
- Ablation, in which there is an irreversible dot destruction of the surface layers of the dermis. This method is the most effective, but requires longer rehabilitation. The processing takes place with Erbium (er: YAG), Neodymium (ND: YAG) or Carbo dioxide (Co)2) Laser, wavelength length of a photon beam - from 1440 nm. In most cases, when you talk about laser fractional rejuvenation, you mean exactly ablative.
- Not leaf, with a milder effect, the jet wavelength is 825–1350 Nm. In this case, severe heating of the tissue occurs to change the structure of protein molecules.
The first technology is most widespread.
The duration of the impulses, its frequency, the energy density and the number of points with a laser beam are adjustable dependent on the processing tasks. With its increase, the destruction of tissues increases. Fraxel Re: Couples laser with a wavelength of 10. 600 Nm and its analogues are more effective (1 method corresponds to 3-4 sessions on another equipment) because it offers a deep effect. However, the rehabilitation period of up to 5 to 7 days increases and serious anesthesia is required.
Omolat using laser techniques ensures course treatment. The number of procedures is individually and fluctuates in the interval of 3-10 sessions.
Implementation of the procedure
Before treatment, it is necessary to consult a doctor and inform him about the medication taken. Some of them (products, the thin blood, isotinoid and others) have to be canceled a few months before the first session.
The preparation of the skin of the face for the rejuvenation process includes the following manipulations:
- Cleaning cosmetics.
- Antiseptic treatment.
- Use of an anesthesia drug local action, extract for 40-60 minutes.
- The impression of a contact gel layer for even gliding the sensor (it is not required for models of lasers of the last generation).
Immediately during processing, the doctor carries out the tip of the device on the skin along straight lines in different directions. The nozzles used have a size of 7x7 or 15x15 mm, an area of 0, 5–2 cm is highlighted in one round2.
The duration of the session depends on the size of the processed surface. On average, it is about 20 minutes for the whole face.
After the procedure, the lubricant is washed off, the face is washed with foam, a soothing and moisturizer is applied. The next processing will take place after 3-4 weeks.
Used drugs
An analgesic gel (ointment) and a special lubricant are used in the fractional laser rejuvenation. Other drugs are not used. In the event of deep effects, it is recommended to apply ointment to the skin processed after the procedure.
Specialized centers also offer professional care cosmetics for intensive rejuvenation methods: restoration and moisture creams, correction gels to reduce the density of scars and other skin defects (lifting gel, correctional and others).
Rejuvenation results
Field laser rejuvenation shows good results that have been clinically confirmed:
- At the point of the rough connective tissue from which the scars are formed, a new one is formed. Thin scars disappear completely, and after 4-5 sessions, wide scars are less noticeable. A positive dynamic is observed within one month of the course of the procedures.
- Small folds disappear, including a "network" around the eyes.
- In the presence of a post -acne, the soil of the craters are paved with the level of the surrounding areas of the skin. The result is visible after the second intervention, and overall it is necessary to complete 5-7 sessions.
- The skin of the face gains a "fresh" look, its elasticity improves.
- The complexion is aligned, pigmented spots become paler.
The reduction in hyperpigmentation is set according to the first procedure. In this case, the mechanism of exposure to the laser beam differs from other methods. Fraxel technology destroys cells that produce and accumulate melanin. Other cells are formed at the site of dead cells that synthesize the normal amount of pigment.
The most pronounced rejuvenation manifests itself in people in young and middle age with thin skin.The duration of the effect is individual and decreases under the influence of the following factors:
- a decrease in the reactivity of the body under the influence of an undesirable environment;
- Age;
- Bad nutrition and bad habits;
- Accompanying diseases;
- a change in hormonal status;
- polluted genetic inheritance;
- Increased thickness of the skin layer of the skin.
The lifting effect due to the treatment is secondary and is based on the fact that the skin becomes denser and healthy. Experts recommend after a complete course on Fraxel Technology to carry out 1 support procedure annually.
