In modern dermatology and cosmetology, a large number of methods have been developed to correct changes related to age in the face. Laser Rejuvenation field is one of the methods that are not in the fight against aging. Compliance with laser correction technologies are becoming more popular because of their technical simplicity and short recovery period.
The principle of operation of the fraction laser
Unlike the classic laser grinding, in which the entire surface layer of skin is evaporated, the fractional laser works directed.Tissue rejuvenation is associated with the phenomenon of hormosis - stimulating the processes of recovery under the influence of stress, whose power is insufficient to manifest harmful consequences.In this case, the laser beam, which causes the tissues to heat up to 45-90 ° C. Since the contact time of the light beam with the skin acts as a tension factor (up to 0, 0003 C), the increase in temperature in a small area of 100 microns. The heat is not transmitted to the surrounding tissues.
Distinguishing 2 main types of fractional laser impact - ablation and not -Abatian road
After tissue treatment, the inflammatory process is carried out with a laser beam, but the sinewy 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 the healthy tissues around the heating zone, the intensive production of collagen and elastin begins, the metabolic processes increase. As a result, the skin becomes more smooth, elastic, the moisture content increases.
The examination of the hormosis process is performed at Volat-Fructus Volat at elevated ambient temperatures. For those who survived the thermal stress, life expectancy was higher than among the insects in the control group contained under normal conditions. Perhaps the production of heat shock proteins and such wellness procedures such as bath, sauna and ice -hardening are also connected.
The duration of the rehabilitation period with fractional laser rejuvenation is reduced as the skin damage is small and not continuous. The surface for thermal exposure is about 20%. Dead cells, melanin pigment and other metabolic products are partially absorbed by macrophages that seek to penetrate the area of inflammation. The rest of these substances are replaced to the surface of the skin 3-7 days after laser treatment. After 4-14 days, full tissue repair occurs.
Indications for use
In the following cases, a person's laser rejuvenation of a person is used:
- Elimination of signs of skin aging:
- reduction of elasticity;
- Extended pores;
- Uneven color.
- Smoothing static and facial wrinkles, including delicate areas near the eyes, on the eyelids to the eyelashes.
- Treatment of melasma, pigment spots (liver, sunny, age, hormonal).
- Scars correction, postoperative scars, uneven texture.
- Treatment of skin defects that result from acne.
Faction laser rejuvenation technology
In modern cosmetology, 2 methods are used, which are radically different by the method of influence on the skin:
- Ablation, in which there is an irreversible destruction of the points of the surface layers of the dermis. This method is the most effective, but requires prolonged rehabilitation. Processing is done using Erbium (Er: YAG), Neodimov (ND: YAG) or carbohydrate dioxide (Co2) Laser, wavelength of a photon beam - from 1440 nm. In most cases, when they talk about laser fractional rejuvenation, they mean precisely ablast.
- Non-payment, with a softer effect, the wavelength of the beam is 825–1350 nm. In this case, the severe heating of the tissues occurs to a change in the structure of the protein molecules.
The first technique is the most widespread.
The duration of impulses, their frequency, energy density and the number of laser beam points are adjustable depending on the tasks of processing. With their increase, respectively, the destruction of the tissues increases. Fraxel Re: Double lasers with a wavelength of 10 600 nm and its analogs are more effective (1 procedure is equivalent to 3-4 sessions of other equipment) as it provides a deep effect. However, the rehabilitation period to 5-7 days increases and serious anesthesia is required.
OMOLATE Using laser techniques provides treatment for the course. The number of procedures is individual and fluctuates in the interval of 3-10 sessions.
Conducting the procedure
Before treatment, it is necessary to consult a doctor, to inform him of the medicines taken. Some of them (products that thin blood, isotinoid and others) should be canceled several months before the first session.
Facial skin preparation for the rejuvenation procedure includes the following manipulations:
- Cleaning cosmetics.
- Antiseptic treatment.
- Administration of anesthetic medicine with local action, excerpt for 40-60 minutes.
- The application of a contact gel layer for even sliding sensor (not necessary for the latest generation laser models).
Directly during processing, the doctor conducts the tip of the device on the skin on straight lines in different directions. The nozzles used have a size 7x7 or 15x15 mm, an area of 0, 5–2 cm is highlighted in one passage2S
The duration of the session depends on the size of the treated surface. It is on average for the whole face in about 20 minutes.
After the procedure, the lubricant is washed, the face is washed with foam, applied a soothing and moisturizer. The next processing is done after 3-4 weeks.
Used medicines
Analgesic gel (ointment) and a special lubricant are used for fractional laser rejuvenation. Other medicines are not used. For deep effects, it is recommended to apply ointment to the treated skin treated after the procedure.
Specialized centers also offer professional care cosmetics designed for intensive rejuvenation methods: restoration and moisturizing creams, correction gels to reduce scars density and other skin defects (gel lifting, correction gel, etc. ).
Rejuvenation
Laser Rejuvenation field demonstrates good results, confirmed clinically:
- At the site of the coarse connective tissue, a new one is formed, from which the scars are formed. The thin scars completely disappear and the broad scars become less noticeable after 4-5 sessions. Positive dynamics are observed within a month after the procedures.
- Small wrinkles disappear, including the "net" around the eyes.
- In the presence of a post, the bottom of the scars of the crater is leveled with the level of the surrounding areas of the skin. The result is evident after the second procedure and it is generally 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 spots become more bluish.
The reduction of hyperpigmentation is fixed after the first procedure. The mechanism of exposure to the laser beam in this case differs from other methods. Fraxel Technology destroys cells that produce and accumulate melanin. In the place of the dead cells, others are formed, which synthesize the normal amount of pigment.
The most pronounced rejuvenation is manifested in people of young and middle age with thin skin.The duration of the effect is individual and decreases under the influence of the following factors:
- reducing body reactivity under the influence of an unfavorable environment;
- age;
- poor nutrition and bad habits;
- concomitant diseases;
- change in hormonal status;
- burdened genetic heredity;
- Increased thickness of the dermal layer of the skin.
The effect of lifting as a result of treatment is secondary and is due to the fact that the skin becomes more dense and healthy. Experts recommend after a full Fraxel Technology course for conducting 1 maintenance procedure annually.
