Hardware cosmetology, as a separate branch of aesthetic medicine, appeared relatively recently, but quickly became widespread due to high efficiency and prolonged preservation of the result.
Laser rejuvenation of the face not only serves as one of the most effective methods for combating the first signs of aging. The procedure allows you to remove deep wrinkles, scars, scars, irregularities of the skin from the face and, restore an even and healthy color, increase the metabolic activity of epidermis and dermis cells.
Under the influence of laser radiation on the fabric, several physical processes are observed: reflection, absorption and passage. As a rule, these phenomena occur simultaneously, and the ratio between them is determined by the parameters of the directional effect. Almost all biomolecules, including protein compounds, water molecules, melanin, oxyghemoglobin, etc. are targeted for laser radiation. The action of the laser in aesthetic medicine is based on the transformation of the energy of the electromagnetic field into thermal.
As a result of absorption by tissues, focal hyperthermia occurs, which can cause reversible and irreversible changes in the epidermal cover:
- up to 45ºС - the destruction of protein molecules and violation of the integrity of cell membranes;
- up to 60ºС - coagulation and death of tissues;
- up to 100ºС - dehydration;
- up to 150ºС - an increase in carbon content;
- Up to 300ºС - vaporization.
Penetrating deep into the epidermis tissues, laser radiation is partially absorbed and dissipated, as a result of which the temperature of the surrounding cells occurs. A rejuvenating cosmetic defect is achieved, properly exposing the wave parameters.
In general, all types of laser treatment can be divided into two types:
- Ablation interventions used to dissect tissues and removal of cysts, wen, etc. CO2 laser is used to carry out such procedures.
- Non -abultition interventions do not have a damaging effect on the epidermal cover. It is this technique using diode neodymium laser that is the main in cosmetology. The non -ablation effect is unique, since the effect of its influence continues for a certain time after the procedure.
To achieve the expected result from the rejuvenation session, it is necessary to take into account the so -called thermal relaxation time. For dermis and epidermis, it is 25-600 ms. In other words, the exceeding the duration of the laser exposure will not lead to a further increase in tissue temperature, but will increase the overheating of others.
That is why cosmetic procedures using this technique necessarily require the additional use of skin cooling sources. The session is performed with a non -contact laser, which is a Svetoper enclosed in the manipulator with a diverging laser radiation bundle. Sometimes a focus nozzle is put on a manipulator, which allows you to create the optimal geometry of a laser beam.
When conducting skin rejuvenation, the beam penetrates to a depth of about 0. 01 cm, "starting" metabolic processes in the dermis cells, accelerating the synthesis of collagen and elastin, improving microcirculation, the flow of oxygen and nutrients.
Currently, laser rejuvenation of the face is usually performed by fractional effects. In other words, the skin processing is carried out not directed, but by a dispersed bundle, which enters the epidermis in the form of a kind of web. There are several methods of performing the procedure, and each has its own "pros" and "minuses". The necessary is selected depending on the age of the woman, the condition of the skin and the general indications for the conduct.
All about rejuvenation
Laser rejuvenation can be:
- Superficial.According to doctors, it is the most gentle and safe method of influence. But it is effective only for the correction of minor defects in the face and body skin and eliminating small facial wrinkles.
- Middle.Compared to superficial, it allows you to solve a wider range of problems: to eliminate pigmentation disorders, restore the skin, give it a healthy look, leve facial and age wrinkles. Due to deep effects on the skin, the procedure sometimes requires the use of drugs for local anesthesia. In some cases, the middle laser rejuvenation is carried out using CO2 lasers. A similar procedure is called dermabrasion and has an intensive effect on the cells of the epidermal cover of the face.
- Deep.During the manipulation, the effect occurs at the maximum permissible level. A laser therapy session is accompanied by strong enough pain, so it is carried out under local or general anesthesia. The recovery period takes a relatively long time, however, the effect lasts up to 1-1. 5 years. The procedure has a powerful effect on cells, and in addition to eliminating wrinkles, adjusts the shape of the oval of the face.
It is worth noting
A more modern type of laser rejuvenation is biorevitalization. The essence of the procedure is the preliminary application of nutrient serum with hyaluronic acid to the skin, which can significantly increase the efficiency of exposure.
Like any other ways of combating signs of aging, laser rejuvenation has its own "pros" and "minuses". If we talk about the advantages, first of all, such cosmetic manipulation stimulates the work of their own skin cells.
As a result, the synthesis of collagen and elastan increases - this is a kind of "frame" that supports the outline of the contour of the face. The result can be seen in numerous photos on the Internet. In addition, the procedure is absolutely safe, the result of its implementation is comparable to surgical methods, however, laser rejuvenation is non-invasive, the recovery period takes a little time, and the effect persists at least 8-12 months.
The variety of techniques allows you to choose the method of laser rejuvenation individually in accordance with the age and condition of the skin. Disadvantages include dependence on the quality of equipment and qualifications of a specialist. Therefore, in order to avoid unpleasant "surprises", you should study the reviews, perhaps consult on the forums and very responsibly approach the choice of the clinic. Conducting the middle and deep peeling is accompanied by unpleasant sensations, but they easily stop anesthetics.
Also, the procedure of laser rejuvenation cannot be carried out in the hot season, since several days after the session it is necessary to protect the skin of the face from the action of sunlight.
Laser rejuvenation: readings and restrictions, technique, subsequent care
Given the effect of the effect, the procedure is recommended by almost all women over 35 years old (naturally, provided there are no contraindications), as an optimal way of quick rejuvenation of the face.
However, pay more attention to such a technique for:
- the presence of wrinkles, sagging of the skin and other defects associated with age;
- violation of the production of melanin pigment cells and caused by such a disorder of the color of the skin, the occurrence of age spots;
- the presence of small scars, scars, after injuries, cosmetic procedures, on the site of acne;
- withering of the skin associated with microcirculation disorders, a slowdown in metabolic processes, a deficiency of secretion of collagen and elastin;
- acne, inflammatory rashes on the skin of the face.
The rejuvenation of a face with a laser is contraindicated in such cases:
- pregnancy;
- the period of lactation due to the danger of the ingredients of the anesthetic into breast milk;
- acute inflammatory dermatoses on the face, regardless of their etiology;
- psoriasis;
- eczema;
- exacerbation of herpetic viral infection;
- ARVI, fever, exacerbation of chronic infections (such conditions are a relative contraindication, the procedure can be carried out after recovery);
- pronounced immunodeficiency;
- impaired functioning of the blood coagulation system;
- diabetes mellitus;
- hypertension, thrombophlebitis of the vessels of the face, serious disorders of cardiac activity;
- an allergic reaction to drugs for local anesthesia;
- rehabilitation period after abdominal operations or personal surgery;
- the presence of damage to the skin of the face.
It is worth noting
The rejuvenation of a face with a laser with vitiligo or a genetic predisposition to such a disease remains very controversial. But most cosmetologists recommend choosing another method of combating signs of aging.
After the preliminary discussion with the patient, the main nuances of the procedure, the specialist allows the time and day of the session. Before starting the skin of the skin with laser radiation, the face is cleaned of cosmetics residues, then anesthetic is applied, and protecting glasses are put on the patient.
After 10-15 minutes, the rejuvenation session directly begins. The duration of the procedure depends on the field of exposure. If it includes not only the face, but also the neck with the neckline, the duration of the session is up to 60 minutes.
It is worth noting
The required number of sessions is selected individually. As a rule, 2-3 visits to a cosmetologist with an interval of 4-8 weeks are enough. For further prevention of age-related skin changes, the procedure is repeated every 6-8 months.
Laser rejuvenation is a serious load on the cells of the epidermal cover, therefore, in order to prevent complications, it is necessary to adhere to certain rules of skin care.
Immediately after the procedure, the cosmetologist makes a cream or serum that accelerates the regeneration processes. Before the complete restoration of the structures of the epidermis, the area of sunlight treated with a laser beam should be avoided.
Therefore, if this zone is not covered with clothes, it is necessary every time before going outside to apply a special sunscreen with the maximum value of SPF.
Also, for 1-2 weeks after the procedure, you should regularly use a moisturizing serum, which will be recommended by the cosmetologist, scrubs, masks, peels are strictly prohibited. For several days after laser rejuvenation of the skin, tonal cream, powder, blush and other similar makeup products cannot be used.
Laser rejuvenation of the skin of the face: the effect of the procedure, possible complications, cost and reviews
The result of the session can be estimated after 3-4 days.
Patients note:
- smoothing facial and age -related wrinkles;
- a capture of the oval of the face;
- elimination of pigment spots, leveling skin color;
- the disappearance of acne, black dots, vascular stars and other defects;
- pore narrowing;
- The disappearance of dark circles under the eyes.
To evaluate the effect of laser rejuvenation, it is enough to look at the photos of women before the procedure and after it. The skin looks noticeably better, becomes more fit, acquires a healthy and young look. As a rule, the exposure session is well tolerated. But the most common complication is severe hyperemia and edema.
Such symptoms do not occur immediately, but after a few hours. Usually everything goes on 2-4 days. Occasionally, women note skin peeling, which is easy to eliminate and prevent with moisturizers. The transition of chronic dermatoses to the active phase is extremely rare, in single cases, pigmentation disorders appear.
It is worth noting
The cost of the session depends on the area of the processed area. Usually, laser rejuvenation of the skin of the face, neck and neckline costs approximately 26-30 thousand rubles.
On the one hand, the price of the procedure is relatively high, but on the other hand, a similar technique is an adequate alternative to plastic surgery.
