In modern dermatology and cosmetology, a large number of ways to correct age -related changes have been developed. Medan laser rejuvenation is one of the uncertain ways to combat aging. The growing laser correction technology has become increasingly popular due to technical simplicity and short recovery periods.
Principles of Operation Laser Fractions
Unlike classic laser grinding, where the entire surface layer of the skin is evaporated, the laser fractions work pointwise.Tissue rejuvenation is associated with the phenomenon of hormesis - a stimulation of the recovery process under the influence of pressure, inadequate strength to indicate dangerous consequences.In this case, the laser beam, which leads to tissue heating up to 45-90 ° C. Since the time of light beam contact with the skin, it acts as a pressure factor (up to 0. 0003 C), an increase in temperature in a small area of 100 microns. Heat is not sent to the surrounding tissue.
Differentiating 2 main types of laser effects of fractions - ablation and non -
After processing the tissue, the inflammation process occurs with the laser beam, but the skin layer remains intact. Thermal pressure stimulates the production of special biological active protein and activation of cellular activity aimed at survival. In healthy tissues around the heating area, collagen and elastin intensive production begins, the metabolic process is enhanced. As a result, the skin becomes smoother, elastic, moisture content increases.
Hormetical process studies are performed at volators at high ambient temperatures. For individuals who survive with heat stress, the lifespan is higher than insects in the control group contained in normal conditions. Perhaps, the production of heat shock proteins and health procedures such as baths, sauna and hardening in ice water are also associated.
The duration of recovery with laser rejuvenation is reduced, as skin damage is small, and not persistent. The surface area under heat exposure is about 20%. Dead cells, melanin pigments and other metabolic products are partly absorbed by macrophages seeking to penetrate the inflammation zone. The rest of these ingredients are replaced to the skin 3-7 days after laser processing. After 4-14 days, complete tissue recovery.
Hints to use
A person's field laser rejuvenation is used in the following cases:
- Elimination of signs -Skin aging:
- decrease in elasticity;
- expanded pores;
- Uneven color.
- Smooth static wrinkles and face, including fine areas near the eyes, on the eyelids to the eyelashes.
- Treatment of melasa, spots -pigment spots (liver, bright, age, hormones).
- Scarring correction, postoperative scars, uneven textures.
- Treatment of skin defects, which is a result of acne.
Laser rejuvenation technology
In modern cosmetology, 2 methods are used, which is basically different in the effects of the skin:
- Ablation, where there is an irreversible point of repaired point layer of the dermis. This method is the most effective, but requires prolonged recovery. Processing is carried out using erbium (ER: yag), neodymium (nd: yag) or carbo dioxide (co2) Laser, Foton beam long length - from 1440 nm. In most cases, when they talk about the rejuvenation of laser breakdowns, they mean exactly ablative.
- No blindness, with a lighter effect, the beam length is 825-1350 nm. In this case, severe tissue heating occurs to changes in the molecular structure of the protein.
The first technique is the most widespread.
The period of pulse, frequency, energy density and number of points with adjustable laser beams depend on the processing task. With the increase in their respective, the destruction of tissue increases. Fraxel Re: Laser pair with a wavelength of 10, 600 nm and its analogue is more effective (1 procedure equals 3-4 sessions on other equipment), as it has a profound effect. However, the recovery period of up to 5-7 days increases and serious anesthesia is required.
Omolate uses laser techniques providing course treatment. Number of procedures individually and fluctuating within 3-10 sessions.
Performing the procedure
Before treatment, you should consult a doctor, inform him about the medications he is taking. Some of them (blood -thin products, isotinoids and others) must be canceled several months before the first session.
Provides facial skin for rejuvenation procedures including the following manipulation:
- Cosmetic cleaning.
- Antiseptic treatment.
- Apply local anesthetic drugs, quotes for 40-60 minutes.
- The application of a touch gel layer for a uniform sliding sensor (it is not required for the last generation laser model).
Directly during processing, the doctor runs the end of the device on the skin along the straight line in various directions. The nozel used has a size of 7x7 or 15x15 mm, area 0. 5-2 cm highlighted in one quote2.
The duration of the session depends on the size of the processed surface. Flat -Rata, it is for the entire face for about 20 minutes.
After the procedure, the lubricant is washed, the face is washed with foam, used for soothing and moisturizing. The next processing is carried out after 3-4 weeks.
The drugs used
In fractional laser rejuvenation, analgesic gel (ointment) and special lubricants are used. Other drugs are not used. With a profound effect, it is recommended to apply ointment on treated skin processed after the procedure.
Special centers also offer professional cosmetics designed for intense rejuvenation methods: restoring and moisturizing creams, recovery gels to reduce scarring density and other skin defects (lifting gel, recovery gel and more).
Rejuvenation
Field laser rejuvenation shows good -bye results clinically:
- The newly formed in the place of coarse connective tissue in which the scar is formed. The thin scars are completely lost, and the wide scar becomes less noticeable after 4-5 sessions. Positive dynamics are observed within a month after the procedure.
- Small wrinkles disappear, including "clean" around the eyes.
- With the presence of Post -acne, the bottom of the crater scars is equated with the level of the area around the skin. The results can be seen after the second procedure, and overall it is necessary to take a 5-7 session course.
- The skin has a "fresh" appearance, the elasticity improves.
- The complex is coordinated, the pigmented place becomes paler.
Reducing hyperpigmentation is prescribed after the first procedure. The mechanism of exposure to laser beams in this case is different from other methods. Fraxel technology destroys cells that produce and collect melanin. At the site of dead cells, others are formed that synthesize the amount of ordinary pigments.
The most significant rejuvenation is shown in young and middle -aged people with thin skin.The duration of the impact is individual and decreases under the influence of the following factors:
- decrease in body reactivity under the influence of poor environment;
- age;
- poor nutrition and bad habits;
- Disease equivalent;
- changes in hormone status;
- the genetic descent of the burden;
- Increased thickness of the skin layer.
The lifting effect of treatment is secondary and is due to the fact that the skin is more dense and healthy. Experts recommend after a full course on fraxel technology to carry out 1 support procedure each year.
