The main reason for skin aging is a deterioration in the functional capacity of metabolism and cell growth, as well as a slowdown in the removal of toxins and toxins and a decrease in the supply of nutrients to cell structures. Thanks to laboratory studies it has been learned that it is a reversible process, that is, there is always the possibility of activating cellular activity. Scientists have found that after thermal exposure to the laser, part of the dermis cells are activated and the other part dies. As a rule, dead cells die rather than living cells which lack the potential for further recovery.
In the process of death of weak cells, the freed intercellular space is occupied by stronger cells. The thermal effect that appears after the laser treatment activates cellular activity, resuming cell renewal and growth. The quality and speed of cell repair depend on the diameter of the laser beam. Its thickness should not be more than 200 microns, so a layer of healthy and young skin will begin to form in the treated area.
For this reason, the laser rejuvenation technique has been improved with the introduction of fractional thermolysis. In this process, the laser beam is split into many microscopic beams, creating an impact network structure on the treatment area. The innovative value of the technology lies in the fact that the laser works in local areas, which preserves intact skin areas - accelerates skin regeneration and healing.
Variety of fractional thermolysis
Fractional laser rejuvenation has been used successfully to firm and firm the skin in one of two ways. They differ in the characteristics of the laser action, the depth of its penetration and the impact on some areas.
The first method of action - fractional photothermolysis - affects the upper epidermal cells, literally causing them to evaporate. In other words, with this method, only the upper dermal layer is exposed.
The second method of treatment affects the lower layers of the epidermis and dermis, leaving the upper layer of the skin intact. In both cases, the laser beam has a local effect. A cell programming zone is preserved around the treated areas, which constitutes the potential for further skin regeneration. In other words, heat shock activates the growth of new cells and metabolic processes in the cells.
The first method of fractional photothermolysis removes the surface microscopic areas of skin cells, firms the treated areas in a short time, so the results after the procedure are immediately noticeable. It relaxes superficial wrinkles and is therefore considered ideal for eliminating the first signs of age-related skin changes.
The second method of laser influence is suitable for solving deep skin problems, when the aging process is already irreversible. This method is a kind of "heavy artillery" of laser rejuvenation. By acting on the deep layers of the epidermis and dermis, the laser starts the metabolic processes, forms a new membrane structure, activates the production of collagen, so the skin becomes younger and regenerates from the inside.
It has been shown that the maximum efficiency of fractional photothermolysis is achieved through the combined use of two exposure methods. In this case, the skin will receive a double effect, both outside and inside, which provides a long-term effect of skin rejuvenation. A similar technique is used by a huge number of modern medical institutions that have modern laser equipment at their disposal.
Efficiency of the procedure
You can make sure that after the fractional laser rejuvenation your skin becomes even, smooth and radiant after the first procedure. Within a week, the oval of the face will shrink noticeably, wrinkles will be smoothed and the complexion will even out. To consolidate and extend the result, a course of procedures at monthly intervals will be required.
With combined fractional rejuvenation, the effect of youthful skin is achieved much faster and lasts longer, up to 2-3 years. Of course, the results are highly dependent on the individual patient's lifestyle. Abandoning bad habits, preventative face care, a healthy lifestyle, proper and proper sleep help prolong the youthfulness of the skin and prevent the aging and fading process.
The undoubted advantage of the procedure is its painlessness. The specialist uses superficial anesthesia, so during the procedure the patient feels only a slight tingling sensation in the affected area.
Procedure progress
The undoubted advantage of the procedure is its painlessness. The specialist applies superficial anesthesia, therefore, during the procedure, the patient feels only a slight tingling sensation in the affected area. The anesthetic is applied shortly before the start of the session, the duration of which can be up to an hour - it all depends on the surface of the treatment.
After the procedure, the specialist advises the client on the necessary skin care, treating it with special medicines.
Immediately after the procedure, the skin does not need additional care. It will take a little over a week to return to the normal pace of life, while rehabilitation after surgery takes much more difficult and more time.
During the first two days, the face will be swollen, after which it will turn slightly red. After 4-7 days, the dead cells will begin to purify, revealing a fresh and youthful skin.
Indications for the procedure
If there are doubts about the effectiveness of fractional laser rejuvenation, then it is worth visiting the procedure to start according to the indications, of which there are many:
- Akne.
- Pigmentation.
- Spider veins, stretch marks and scars.
- Enlarged pores.
- Wrinkles, crow's feet around the eyes.
- Flabby, shriveled and flabby skin.
Contraindications to the procedure
As with any salon procedure, fractional rejuvenation has a number of contraindications:
- Benign and malignant growths in the treatment area.
- Cancer and chemotherapy in progress
- Dermatosis and photodermatosis, in the procedure area.
- Herpes infection within one month.
- Acute infectious infections, immunodeficiency.
- Chronic diseases such as bleeding disorders, diabetes mellitus, thromboembolic diseases.
- Psoriasis and hypertension.
- History of keloid or vitiligo scarring, family history of vitiligo or keloid.
- Fresh tan, recent tanning visit.
- Period of pregnancy and lactation.
- Use of retinoids in the past six months.
Combination of fractional rejuvenation with other procedures
This procedure is always carried out only after a preliminary consultation with a cosmetologist. With marked age-related changes, laser skin resurfacing will bring maximum efficiency and not a fractional rejuvenation method.
In some cases, it will not be possible to do without surgical manipulations, that is, endoscopic lifting, blepharoplasty or the introduction of threads for tightening. However, laser rejuvenation will help maintain and improve the effectiveness of the procedures. It will complement their results and refine the customer's appearance.
Laser rejuvenation methods are perfectly combined with procedures such as mesotherapy and plasma lifting, as well as biorevitalization based on hyaluronic acid.
