In modern dermatology and cosmatology, a large number of methods have been developed to correct changes related to the face in the face. The rejuvenation of the field laser is one of the non -fidic methods to combat aging. Ensuring laser correction technologies are becoming increasingly popular due to their technical simplicity and their brief recovery period.
The principle of operation of the fractional laser
Unlike the classic laser rectifier, in which the entire surface layer of the skin evaporates, the fractional laser works.The rejuvenation of the tissues is associated with the phenomenon of the Hormesis: the stimulation of the recovery processes under the influence of stress, whose resistance is insufficient to manifest harmful consequences.In this case, a laser beam, which leads to tissue heating at 45-90 ° C. Since the contact time of the light with the skin, acts as a stress factor (up to 0. 0003 C), the temperature increase in a small area of the order of 100 microns. The heat is not transmitted to the surrounding tissues.
Distinguish 2 main types of fractional laser impact - ablation and not abroad
After processing the tissues, there is an inflammatory process with a laser beam, but the tacañosa layer of the skin remains intact. Thermal stress stimulates the production of special biologically active proteins and the activation of cell activity aimed at survival. In healthy tissues that surround the heating area, intensive collagen and elastin production begins, metabolic processes are improved. As a result, the skin becomes softer, elastic, moisture content increases.
The study of the Hormesis process was carried out in volat-fructus volat to high environmental temperatures. For those individuals who survived with thermal stress, life expectancy was greater than among insects in the control group contained in normal conditions. Perhaps, the production of thermal shock proteins and such well -being procedures such as a bathroom, a sauna and hardening in ice water are also associated.
The duration of the rehabilitation period with fractional laser rejuvenation is reduced, since skin damage is small and not continuous. The surface area under thermal exposure is approximately 20%. Dead cells, melanin pigment and other metabolic products are partially absorbed by macrophages that strive to penetrate the inflammation zone. The rest of these substances are supplanted to the skin surface 3-7 days after laser processing. After 4-14 days, the complete restoration of the tissues occurs.
Indications for use
A person's field laser rejuvenation is used in the following cases:
- Elimination of skin aging signs:
- decrease in elasticity;
- expanded pores;
- Unequal color
- The soft and facial wrinkles, including delicate areas near the eyes, in the eyelids to the eyelashes.
- Melasms treatment, pigment spots (liver, sunny, age, hormonal).
- Scars correction, postoperative scars, unequal texture.
- Treatment of skin defects, which are a consequence of acne.
Fractional laser rejuvenation technology
In modern cosmetology, 2 methods are used, which are fundamentally different in the method of influence in the skin:
- Ablation, in which there is an irreversible punctual destruction of the surface layers of the dermis. This method is the most effective, but requires prolonged rehabilitation. The processing is carried out using Erbium (er: yag), neodymium (nd: yag) or carbo2) Laser, wavelength length of a photon beam - 1440 nm. In most cases, when they speak of laser fractional rejuvenation, they mean precisely ablative.
- Non-gluto, with a softer effect, the wavelength of the beam is 825-1350 nm. In this case, severe warming of tissues occurs to a change in the structure of protein molecules.
The first technique is more widespread.
The duration of the pulses, their frequency, energy density and the number of points with a laser beam are adjustable depending on processing tasks. With its increase, respectively, the destruction of tissues increases. Fraxel Re: The pairs lasers with a wavelength of 10, 600 nm and their analogues are more effective (1 procedure is equivalent to 3-4 sessions on another team), since it provides a deep effect. However, the rehabilitation period of up to 5-7 days increases and severe anesthesia is required.
Omolate using laser techniques provides the course treatment. The number of procedures is individually and fluctuates in the interval of 3-10 sessions.
Performing the procedure
Before treatment, it is necessary to consult a doctor, inform him about the medications taken. Some of them (products that thin blood, isotinoid and others) must be canceled a few months before the first session.
The preparation of the skin of the face for the rejuvenation procedure includes the following manipulations:
- Cosmetics cleaning.
- Antiseptic treatment
- Applying an anesthetic drug drug, extract for 40-60 minutes.
- The imposition of a contact gel layer for the uniform sliding of the sensor (it is not necessary for laser models of the latest generation).
During the processing, the doctor performs the tip of the device on the skin along the straight lines in several directions. The nozzles used have a size of 7x7 or 15x15 mm, an area of 0. 5–2 cm is highlighted in a passage2.
The duration of the session depends on the size of the processed surface. On average, it is for the whole face for about 20 minutes.
After the procedure, the lubricant is washed, the face is washed with foam, applies a soothing and moisturizer. The following processing is carried out after 3-4 weeks.
Used drugs
In fractional laser rejuvenation, an analgesic gel (ointment) and a special lubricant are used. No other drugs are used. With deep effects, it is recommended to apply ointment to treated skin processed after the procedure.
Specialized centers also offer professional care cosmetics designed for intense rejuvenation methods: restoration and hydration of creams, correctional gels to reduce the density of scars and other skin defects (lifting gel, correctional gel and others).
Rejuvenation results
Field laser rejuvenation demonstrates good clinically confirmed results:
- A new one is formed in the place of the rough connective tissue from which the scars are formed. The thin scars disappear completely, and the wide scars become less notable after 4-5 sessions. The positive dynamic is observed within a month after the course of the procedures.
- Little wrinkles disappear, including a "network" around the eyes.
- In the presence of a post -acne, the bottom of the crater scars is level 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, pigmented spots become pale.
The reduction of hyperpigmentation is set after the first procedure. The mechanism of exposure to laser beam in this case differs from other methods. Fraxel technology destroys cells that produce and accumulate melanin. In the site of dead cells, others that synthesize the normal amount of pigment are formed.
The most pronounced rejuvenation is manifested in people of young and medium age with thin skin.The duration of the effect is individual and decreases under the influence of the following factors:
- a decrease in body reactivity under the influence of an adverse environment;
- age;
- Bad nutrition and bad habits;
- concomitant diseases;
- a change in the hormonal state;
- loaded genetic heritage;
- Increase in the thickness of the dermal layer of the skin.
The lifting effect as a result of the treatment is secondary and is due to the fact that the skin becomes dense and healthy. Experts recommend after a complete course on Fraxel technology to carry out 1 support procedure annually.
