The main cause of skin aging is a deterioration in the functional ability of metabolism and cell growth, as well as a slowdown in the elimination of toxins and toxins and a decrease in the supply of nutrients to cellular structures. Thanks to laboratory studies, it became known that this 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, one part of the cells in the dermis is activated, and the other part dies. As a rule, dead cells die rather than living cells that do not have the potential for further recovery.
In the process of death of weak cells, the vacated intercellular space is occupied by stronger cells. The thermal effect that appears after laser treatment activates cellular activity, resuming cell renewal and growth. The quality and speed of cellular repair depends on the diameter of the laser beam. Its thickness should not be more than 200 microns, then 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 a mesh structure of impact 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 - they accelerate the regeneration and healing of the skin.
Varieties of fractional thermolysis
Fractional laser rejuvenation has been successfully used to tighten and firm the skin in one of two possible ways. They differ in the characteristics of the laser action, the depth of its penetration and impact on certain areas.
The first method of action - fractional photothermolysis - affects the upper epidermal cells, literally evaporating them. In other words, with this method, only the upper dermal layer is exposed.
The second method of treatment affects the lower epidermal and dermal layers, leaving the upper layer of the skin intact. In both cases, the laser beam has a local effect. A cellular programming zone is preserved around the treated areas, which forms the potential for further skin regeneration. In other words, heat shock activates the growth of new cells and metabolic processes in cells.
The first method of fractional photothermolysis removes superficial microscopic areas of skin cells, tightens the treated areas in a short time, so the results after the procedure are noticeable immediately. It smoothes out 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 problems deep in the skin, when the aging process is already irreversible. This method is a kind of "heavy artillery" of laser rejuvenation. Acting on the deep layers of the epidermis and dermis, the laser starts metabolic processes, forms a new membrane framework, activates collagen production, so the skin becomes younger and regenerates from the inside.
It has been proven that the maximum efficiency of fractional photothermolysis is achieved through the combined use of two methods of exposure. 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 at their disposal modern laser equipment.
Efficiency of procedure
You can make sure that after fractional laser rejuvenation your skin becomes even, smooth and radiant after the first procedure. Within a week, the oval of the face will noticeably tighten, wrinkles will be smoothed out, and the complexion will even out. To consolidate and extend the result, a course of procedures will be required at intervals of a month.
With combined fractional rejuvenation, the effect of youthful skin is achieved much faster and lasts longer, for up to 2-3 years. Of course, the results depend a lot on the lifestyle of the individual patient. Quitting bad habits, preventive facial care, a healthy lifestyle, proper and proper sleep help to prolong the youthfulness of the skin and prevent the process of aging and fading.
The undoubted advantage of the procedure is its painlessness. The specialist uses surface 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 surface 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 area of the treatment.
After the procedure, the specialist advises the client on the necessary skin care, treats it with special medicinal products.
Immediately after the procedure, the skin does not need any additional care. It will take you a little more than a week to return to your normal rhythm of life, while rehabilitation after surgery takes much more difficult and longer.
During the first two days, the face will be puffy, after which it will turn slightly red. After 4-7 days, dead cells will begin to cleanse, revealing fresh and youthful skin.
Indications for the procedure
If there are any doubts about the effectiveness of fractional laser rejuvenation, then it is worth visiting the procedure to begin with 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.
- Saggy, withering and loose 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 ongoing chemotherapy
- Dermatoses and photodermatoses, in the area of the procedure.
- Herpes infection within a month.
- Acute infectious infections, immunodeficiency.
- Chronic diseases such as bleeding disorders, diabetes mellitus, thromboembolic diseases.
- Psoriasis and hypertension.
- History of keloid scars or vitiligo, family history of vitiligo or keloids.
- Fresh tan, recent tanning visit.
- Pregnancy and lactation period.
- Use of retinoids in the last six months.
Combination of fractional rejuvenation with other procedures
This procedure is always carried out only after a preliminary consultation with a cosmetologist. With pronounced age-related changes, laser skin resurfacing will bring maximum efficiency, and not a method of fractional rejuvenation.
In some cases, it will not be possible to do without surgical manipulations, namely endoscopic facelift, blepharoplasty or insertion of threads for tightening. Nevertheless, laser rejuvenation will help maintain and enhance the effectiveness of the procedures. It will complement their results and refine the client's appearance.
Methods of laser rejuvenation are perfectly combined with procedures such as mesotherapy and plasma lifting, as well as biorevitalization based on hyaluronic acid.
