In modern dermatology and cosmetology, a large number of methods were developed to correct age -related changes on the face of the face. Field laser rejuvenation is one of the non -Drug methods to combat aging. The laser correction technologies saver is becoming increasingly popular due to its technical simplicity and a short recovery period.
The principle of operation of the fractional laser
Unlike classic laser grinding, in which the entire superficial layer of the skin is evaporated, the fractional laser works at the point.Tissue rejuvenation is associated with the phenomenon of hormesia - stimulation of recovery processes under the influence of stress, whose strength is insufficient to manifest harmful consequences.In this case, a laser beam, leading to fabric to warm up at 45 to 90 ° C, from the light beam contact time with the skin, acts as a voltage factor (up to 0, 0003 ° C), the increase in temperature in a small area of 100 microns. Heat is not transmitted to surrounding tissues.
Distinguish 2 main types of laser fractional impact - ablation and no
After tissue processing, an inflammatory process occurs with a laser beam, but the petty layer of the skin remains intact. Thermal stress stimulates the production of special biologically active proteins and the activation of cellular activity intended for survival. In healthy tissues around the heating area, intensive production of collagen and elastin begins, metabolic processes are improved. As a result, the skin becomes smoother, elastic, the moisture content increases.
The study of the hormesia process was conducted at Volat-Fructus Volat at high environmental temperatures. For individuals who survived with thermal stress, life expectancy was higher than among insects in the control group contained under normal conditions. Perhaps the production of thermal shock proteins and good procedures such as bath, sauna and hardening in ice water are also associated.
The duration of the rehabilitation period with laser fractional rejuvenation is reduced as the damage to the skin is small and not continuous. The surface area 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 zone. The rest of these substances is supplanted to the surface of the skin 3-7 days after laser processing. After 4-14 days, the complete restoration of tissues occurs.
Indications for use
A person's field laser rejuvenation is used in the following cases:
- Elimination of signs of skin aging:
- decreased elasticity;
- expanded pores;
- Unequal color.
- The softening of static and facial wrinkles, including delicate areas near the eyes, in the eyelashes of the eyelashes.
- Treatment of melasms, pigment spots (liver, sunny, age, hormonal).
- Correction of scars, post -operative scars, irregular texture.
- Treatment of skin defects, which are a consequence of acne.
Fractional rejuvenation technology of the face laser
In modern cosmetology, 2 methods are used, which are fundamentally different in the method of influence on the skin:
- Ablation, in which there is an irreversible point destruction of the superficial layers of the dermis. This method is the most effective, but requires prolonged rehabilitation. Processing is performed using ERBIUM (ER: YAG), neodymium (nd: yag) or carbo dioxide2) Laser, wavelength of a photon beam - from 1440 nm. In most cases, when they talk about laser fractional rejuvenation, they mean precisely ablative.
- Not bland, with a softer effect, the wavelength of the beam is 825 to 1350 nm. In this case, severe tissue heating occurs for a change in the structure of protein molecules.
The first technique is more widespread.
Pulse duration, frequency, energy density and number of points with a laser beam are adjustable, depending on processing tasks. With its increase, respectively, tissue destruction increases. Fraxel Re: Pair lasers with a wavelength of 10. 600 nm and its analogs are more effective (1 procedure is equivalent to 3-4 sessions on other equipment) as it provides a deep effect. However, the rehabilitation period of up to 5 to 7 days increases and severe anesthesia is required.
Omolate using laser techniques provides course treatment. The number of procedures is individually and floats in the interval of 3 to 10 sessions.
Performing the procedure
Before treatment, it is necessary to consult a doctor, inform it from the medicines taken. Some of them (fine blood, isotinoid and others) should be canceled a few months before the first session.
The preparation of face skin for the rejuvenation procedure includes the following manipulations:
- Cosmetics cleaning.
- Anti -Septic Treatment.
- Applying a local action anesthetic medicine, stretch for 40-60 minutes.
- The imposition of a contact gel layer to slide uniform sensor (not required for last generation lasers models).
During processing, the doctor conducts the tip of the device on the skin along straight lines in various directions. Used nozzles 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, applied a soothing and moisturizing. The next processing is performed after 3-4 weeks.
Used drugs
In the fractional rejuvenation of the laser, an analgesic gel (ointment) and a special lubricant is used. Other medications are not used. With deep effects, it is recommended to apply ointment to the processed skin after the procedure.
Specialized centers also offer professional care cosmetics designed for intense rejuvenation methods: restoration and hydration of creams, correctional gels to reduce scars and other skin density (survey gel, correctional gel and others).
Rejuvenation Results
Field laser rejuvenation demonstrates good clinically confirmed results:
- A new one is formed at the location of the rough connective tissue from which the scars are formed. Thin scars completely disappear, and wide scars become less noticeable after 4-5 sessions. Positive dynamics are observed within a month after the course of procedures.
- Small wrinkles disappear, including a "network" around the eyes.
- In the presence of a post -acne, the bottom of the crater scars is leveled with the level of surrounding areas of the skin. The result is visible after the second procedure and, in total, a course of 5 to 7 sessions is required.
- The skin of the face acquires a "fresh" look, its elasticity improves.
- The complexion is aligned, the pigmented points are pale.
Reducing hyperpigmentation is fixed 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. At the scene of the dead cells, others are formed that synthesize the normal amount of pigment.
The pronounced rejuvenation manifests itself in young people and a half 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 hormonal status;
- overloaded genetic heredity;
- Increased thickness of the dermal layer of the skin.
The survey effect as a result of treatment is secondary and is due to the fact that the skin becomes denser and healthy. Experts recommend after a complete course on fraxel technology to perform 1 support procedure annually.
