In modern dermatology and cosmetology, a large number of methods have been developed to correct changes related to the age in front of the face. The rejuvenation of the laser on the field is one of the non -pharmacological methods to combat aging. The laser correction technologies saved are becoming increasingly popular due to their technical simplicity and the short recovery period.
The operating principle of the fractional laser
Unlike the classic laser adjustment, in which the entire surface layer of the skin is evaporated, the fractional laser works in a punctual way.The rejuvenation of the tissues is associated with the phenomenon of the hormsex: the stimulation of the recovery processes under the influence of stress, whose strength is insufficient to manifest harmful consequences.In this case, a laser beam, which leads to the heating of fabrics at 45-90 ° C. Since the contact time of the ray of light with the skin, acts as a stress factor (up to 0, 0003 c), the increase in temperature in a small area of the order of 100 micron. The heat is not transmitted to the surrounding tissues.
Distinguish 2 main types of fractional laser impact - ablation and not abroad
After processing the fabrics, an inflammatory process occurs with a laser beam, but the stingy layer of the skin remains intact. Thermal stress stimulates the production of special biologically active proteins and the activation of cellular activity aimed at survival. In healthy fabrics surrounding the heating area, the intensive production of collagen and elastin begin, metabolic processes have improved. As a result, the skin becomes smoother, elastic, the humidity content increases.
The study of the Ormese process was conducted to Volat-Firctus at high environment temperatures. For those individuals who survived with thermal stress, life expectancy was higher than among the insects in the control group contained in normal conditions. Perhaps, the production of thermal shock proteins and wellness procedures such as a bathroom, a sauna and hardening in frozen water are also associated.
The duration of the rehabilitation period with fractional laser rejuvenation is reduced, since the damage to the skin is pointed 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 inflammation area. The rest of these substances is supplanted on the surface of the skin 3-7 days after laser processing. After 4-14 days, the complete reset of the fabrics occurs.
Indications for use
The rejuvenation of the laser on a person's field is used in the following cases:
- Elimination of signs of aging of the skin:
- decrease in elasticity;
- expanded pores;
- Irregular color.
- The smoothing of static and facial wrinkles, including delicate areas near the eyes, on the eyelids with the eyelashes.
- Treatment of melasms, pigment stains (liver, sunny, age, hormonal).
- Correction of scars, postoperative scars, irregular consistency.
- Treatment of skin defects, which are a consequence of acne.
Fractional laser rejuvenation technology of the face
In modern cosmetology, 2 methods are used, which are basically different in the method of influence on the skin:
- Ablation, in which there is a destruction of the irreversible point of the superficial layers of the dermis. This method is the most effective, but requires prolonged rehabilitation. The processing is carried out using Erbio (ER: YAG), Neodimio (ND: YAG) or carbo dioxide2) laser, wavelength length of a radius of photons - 1440 nm. In most cases, when they speak of fractional laser rejuvenation, they mean precisely ablative.
- Not blank, with a milder effect, the beam wavelength is 825-1350 Nm. In this case, a serious heating of the fabric occurs to a change in the structure of protein molecules.
The first technique is widespread.
The duration of the impulses, their frequency, the energy density and the number of points with a laser beam are adjustable according to the processing activities. With their increase, respectively, the destruction of the tissues increases. Fraxel Re: The laser paired with a wavelength of 10. 600 Nm and its analogues are more effective (1 procedure is equivalent to 3-4 sessions on another equipment), as it provides a deep effect. However, the rehabilitation period up to 5-7 days increases and serious anesthesia is needed.
Omola that the use of laser techniques involves the treatment of the course. The number of procedures is individually and floats in the interval of 3-10 sessions.
Perform the procedure
Before treatment, you need to consult a doctor, inform it of the drugs taken. Some of them (thin products, isotineids and others) must be deleted a few months before the first session.
Preparing the face skin for the rejuvenation procedure includes the following manipulations:
- Cosmetics cleaning.
- Antiseptic treatment.
- Application of an anesthetic drug of local action, extracted for 40-60 minutes.
- The imposition of a layer of contact gel for the uniform sliding of the sensor (it is not necessary for the last generation laser models).
Directly during the processing, the doctor leads the tip of the device on the skin along the straight lines in various directions. The nozzles used have a size of 7x7 or 15x15 mm, an area of 0, 5-2 cm is highlighted in a ride2.
The duration of the session depends on the size of the elaborate surface. On average, it's all over 20 minutes throughout the face.
After the procedure, the lubricant is washed off, the face is washed with foam, applied a calm and a moisturizing cream. The next processing is performed after 3-4 weeks.
Used drugs
In fractional laser rejuvenation, an analgesic gel (ointment) and a special lubricant are used. Other drugs are not used. With deep effects, it is recommended to apply ointment to the treated skin developed after the procedure.
The specialized centers also offer professional assistance cosmetics designed for intense rejuvenation methods: creams for restoration and moisturizing, corrective gels to reduce the density of scars and other skin defects (lifting gel, corrective gel and others).
RESCRIVANT RESULTS RESULTS
The rejuvenation of the laser on the field shows good clinically confirmed results:
- One new is formed instead of the raw connective tissue from which the scars are formed. The thin scars disappear completely and the large scars become less evident after 4-5 sessions. The positive dynamic is observed within a month after the course of the procedures.
- Small wrinkles disappear, including a "network" around the eyes.
- In the presence of a post -acne, the bottom of the crater scars is leveling with the level of the surrounding areas of the skin. The result is visible after the second procedure and in total it is necessary to take a course of 5-7 sessions.
- The skin of the face acquires a "fresh" appearance, its elasticity improves.
- The complexion is aligned, the pigmented points become clearer.
The reduction of hyperpigmentation is set after the first procedure. The mechanism of exposure to the laser beam in this case differs from the other methods. Fraxel technology destroys cells that produce and accumulate melanin. On the site of the dead cells, others are formed that summarize the normal amount of pigment.
The most pronounced rejuvenation occurs in young and medium people 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 adverse environment;
- age;
- poor nutrition and bad habits;
- concomitant diseases;
- a change in the hormonal state;
- Gradually genetic heritage;
- Increase in the thickness of the dermal layer of the skin.
The lifting effect following the treatment is secondary and is due to the fact that the skin becomes more dense and healthy. Experts recommend after a complete course on Fraxel technology to conduct 1 support procedure every year.
