In modern dermatology and cosmetology, a large number of methods for correcting changes received in the face of persons. The rejuvenation of field lasers is one of the methods that are not protruding against aging. Savings Laser correction technologies are becoming increasingly popular due to their technical simplicity and short recovery period.
Principle of work of the fractional laser
Unlike the classic laser grinding, in which the entire surface layer of the skin evaporates, fractional laser has doubled.Tissue rejuvenation is associated with the phenomenon of hormeze - stimulation of the recovery process under the influence of stress, whose strength is insufficient for the manifesting of harmful consequences.In this case, a laser beam, leading to the heating of tissues to 45-90 ° C. Ever since the contact time of the skin is with skin, it acts as a stress factor (up to 0, 0003 c), temperature increase in 100 microns. Heat is not transferred to the surrounding tissue.
Distinguish 2 main types of fractional laser influence - ablation and non-covering
After processing the tissues, the inflammatory process appears with a laser beam, but a stained layer of skin remains intact. Thermal stress encourages the production of special biologically active proteins and activate mobile activity aimed at survival. In healthy tissues around the heating area, the intensive production of collagen and elastin begins, metabolic processes have improved. As a result, the skin becomes smooth, elastic, increases moisture content.
The study of the process of hormez was performed on the volat-fructus volat on elevated environment temperatures. For those individuals who have survived with thermal stress, the lifespan was higher than among insects in the control group contained under normal conditions. The production of heat stroke proteins and such wellness procedures as a bath, sauna and hardening in ice water is also connected.
The duration of the rehabilitation period with fractional laser rejuvenation was reduced, because skin damage is small, not continuous. The surface under thermal exposure is about 20%. Dead cells, Melanin pigment and other metabolic products are partly absorbed by macrophages that seek to penetrate in inflammation. The rest of these substances is brought to the surface of the skin 3-7 days after laser processing. After 4-14 days there is a complete reconstruction of tissue.
Indications for use
The terrain rejuvenation of a person person is used in the following cases:
- Elimination of skin aging signs:
- a reduction in elasticity;
- expanded pores;
- Uneven color.
- Smoothing static and facial wrinkles, including sensitive surfaces near the eyes, on eyelashes.
- Treatment of tenders, pigment places (liver, sunny, age, hormonal).
- Correcting scars, postoperative scars, uneven textures.
- Treatment of skin damage, resulting from acne.
Fractional Laser Facial Rejuvenation Technology
2 methods are used in modern cosmetology, which are basically different in skin impact mode:
- Ablation, in which there is an irreversible point of destroying the surface layers of Dermis. This method is most effective, but requires long-term rehabilitation. Processing is done using Erbium (ER: YAG), neodymium (ND: YAG) or Carbo Dioxide (CO2) Laser, the length of the wavelength of the photon beam - from 1440 nm. In most cases, when discussing laser fractional rejuvenation, they mean precise ablatives.
- Non-blatome, with a milder effect, wavelength beam is 825-1350 nm. In this case, strong tissue warming occurs in the structure of protein molecules.
The first technique is the most widespread.
The duration of the impulse, their frequency, energy density and the number of points with laser beam are adjustable depending on the processing tasks. With its rise, respectively, the destruction of tissues increases. Fraxel Re: Couple lasers from a wavelength of 10. 600 Nm and its analogues are more efficient (1 procedure is equivalent to 3-4 sessions in other equipment), because it provides a profit effect. However, the rehabilitation period of up to 5-7 days increases and serious anesthesia is needed.
Laser techniques predicts course treatment. The number of procedures is individually and fluctuated in an interval of 3-10 sessions.
Execution of the proceedings
Before treatment, it is necessary to advise with the doctor, notify it of medicines. Some of them (products that thin blood, isotinoinoid and others) must be canceled several months before the first session.
The preparation of the skin of the faces for the rejuvenation process includes the following manipulation:
- Cosmetics cleaning.
- Antiseptic treatment.
- Application of an anesthetic drug of local action, paragraph 40-60 minutes.
- Practice the contact gel layer for uniform sliding sensors (not required for the latest generation laser models).
Directly during processing, the doctor implements the top of the device on the skin with straight lines in different directions. The sounds used to have 7x7 or 15x15 mm size, an area of 0, 5-2 cm is marked in one paragraph2.
The duration of the session depends on the size of the processed surface. It's on average for the whole face about 20 minutes.
After the procedure, the lubricant is being shaped, the face is washed in foam, applied soothing and humidifier. The next processing is done after 3-4 weeks.
Used medications
An analgesic gel (grease) and especially lubricant is used in fractional laser rejuvenation. Other medications are not used. With deep effects, it is recommended to apply the grease in the processed skin processed after the procedure.
Specialized centers also offer cosmetics of professional care designed for intensive rejuvenation methods: Return and moisturizing creams, correctional gels for reducing scarring density and other skin damage (skin lifts).
Rehabilitation results
The rejuvenation of field lasers shows good results confirmed by clinical path:
- A new from which scars form is formed at the site of a rough connective tissue. Thin scars completely disappear, and wide scars become less noticeable after 4-5 sessions. Positive dynamics was observed within a month after the flow of procedures.
- Small wrinkles disappear, including the "network" around the eyes.
- In the presence of the post -Acne, the bottom of the scarring is directly with the level of the surrounding areas of the skin. The result is visible after the second procedure, and a total of 5-7 sessions are required.
- The skin of the face acquires "fresh" appearance, elasticity improves.
- The set is harmonized, pigmented spots become pale.
The reduction of hyperpigmentation has been repaired after the first procedure. The laser beam exposure mechanism in this case differs from other methods. Fraxel technology destroys cells that produce and accumulate melanin. Another that synthesizes the normal quantity of pigment is formed at the place of the dead cells.
The fastest rejuvenation is manifested in people of a young and medium age with a thin leather.The duration of the effect is individual and decreases under the influence of the following factors:
- reduction of body reactivity under the influence of an unfavorable environment;
- Age;
- Bad nutrition and bad habits;
- simultaneous diseases;
- Change of hormonal status;
- loaded genetic heredity;
- Increased thickness thickness of the skin.
The effect of raising as a result of treatment is secondary and due to the fact that the skin becomes thicker and healthier. Experts recommend after a full exchange rate on Fraxel technology for the implementation of 1 support procedure per year.
