The main cause of skin aging is the deterioration of the functional capacity of metabolism and cell growth, as well as slowing the elimination of toxins and toxins and a decrease in the supply of nutrients to cellular structures. Thanks to laboratory studies, it was 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 dermis cells is activated and the other part dies. As a rule, dead cells die instead of living cells that have no potential for later recovery.
In the process of weak cell death, the vacated intercellular space is occupied by stronger cells. The thermal effect that appears after laser treatment activates cell activity, resuming cell renewal and growth. The quality and speed of cell repair depends on the diameter of the laser beam. Its thickness should not exceed 200 microns, so a layer of young, healthy 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 divided into many microscopic beams, creating an impact mesh structure in the treatment area. The innovative value of the technology lies in the fact that the laser acts on local areas, which preserves intact areas of the skin - accelerates the regeneration and healing of the skin.
Varieties of fractional thermolysis
Fractional laser rejuvenation has been used successfully to stretch 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 the impact in 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 treatment method 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 cell programming zone is preserved around the treated areas, which is 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 superficial microscopic areas of the skin cells, tightens the treated areas in a short time, so that the results after the procedure are immediately noticeable. It smoothes surface wrinkles and is therefore considered ideal for eliminating the first signs of age-related skin changes.
The second method of influence of the laser is suitable for solving skin problems, when the aging process is already irreversible. This method is a kind of "heavy artillery" of laser rejuvenation. Acting in the deep layers of the epidermis and dermis, the laser triggers metabolic processes, forms a new membrane structure, activates the production of collagen, so that the skin becomes younger and regenerates inside.
It has been proven 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 external and internal, which provides a long-term skin rejuvenation effect. A similar technique is used by a large number of modern medical institutions that have modern laser equipment at their disposal.
Efficiency of the procedure
You can be sure that after fractional laser rejuvenation, your skin will be uniform, smooth and radiant after the first procedure. In a week, the oval of the face will be visibly tense, the wrinkles will be smoothed and the complexion will be more uniform. To consolidate and extend the result, a series of procedures will be required at intervals of one month.
With combined fractional rejuvenation, the effect of a 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 each patient. Abandoning bad habits, preventive facial care, healthy lifestyle, adequate and adequate sleep help to prolong the youth of the skin and prevent the process of aging and fading.
The indisputable advantage of the procedure is its absence of pain. The specialist uses surface anesthesia, so during the procedure, the patient feels only a slight tingling sensation in the affected area.
Progress of the procedure
The indisputable advantage of the procedure is its absence of pain. The specialist applies surface anesthesia, so during the procedure, the patient feels only a slight tingling sensation in the affected area. The anesthetic is applied just before the start of the session, which can last 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 medications.
Immediately after the procedure, the skin does not need any additional care. It will take you a little over a week to return to your normal pace of life, while rehabilitation after surgery is much more difficult and time consuming.
During the first two days, the face will be swollen, after which it will be slightly red. After 4 to 7 days, the dead cells will begin to cleanse, revealing fresh, young skin.
Indications for the
procedureIf there are doubts about the effectiveness of fractional laser rejuvenation, it is worth visiting the procedure to start according to the indications, which are many:
- Akne.
- Pigmentation.
- Spider veins, stretch marks and scars.
- Large pores.
- Wrinkles, crow's feet around the eyes.
- Flabby, withered and loose skin.
Contraindications for the procedure
As with any salon procedure, fractional rejuvenation has several contraindications:
- Benign and malignant growths in the treatment area.
- Cancer and chemotherapy in progress
- Dermatoses and photodermatoses, in the procedure area.
- Herpes infection within a month.
- Acute infectious infections, immunodeficiency.
- Chronic diseases such as bleeding disorders, diabetes mellitus, thromboembolic diseases.
- Psoriasis and hypertension.
- History of scarring from keloid or vitiligo, family history of vitiligo or keloid.
- 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 performed only after a preliminary consultation with a cosmetologist. With pronounced changes related to age, laser skin resurfacing will bring maximum efficiency, not a fractional rejuvenation method.
In some cases, it will not be possible to do without surgical manipulations, namely endoscopic lifting, blepharoplasty or insertion of wires for tightening. However, laser rejuvenation will help to maintain and increase the effectiveness of the procedures. This will complement your results and improve the client's appearance.
Laser rejuvenation methods are perfectly combined with procedures such as mesotherapy and plasma lifting, as well as hyaluronic acid-based biorevitalization.
