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 cell structures. Thanks to laboratory studies, it became known that this is a reversible process, meaning that there is always the possibility of activating cellular activity. Scientists have discovered that after thermal exposure to lasers, part of the cells in the dermis are activated, and the rest die. As a rule, dead cells die rather than living cells that have no potential for further healing.
In the process of weak cell death, the free intercellular space is occupied by the stronger cells. The thermal effect that appears after laser treatment activates cellular 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 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 renewal technique has been improved with the introduction of fractional thermolysis. In this process, the laser beam splits 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 works in local areas, which preserves the intact areas of the skin - they accelerate the regeneration and healing of the skin.
Fractional thermolysis varieties
Fractional laser rejuvenation has been used successfully to tighten and strengthen the skin in one of two possible ways. They differ in the operating characteristics of the laser, the depth of its penetration and the impact on certain areas.
The first method of action - fractional photothermolysis - affects the upper cells of the epidermis, evaporating them literally. In other words, with this method, only the upper dermal layer is exposed.
The second method of treatment affects the lower layers of the skin and the skin, leaving the upper layer of skin intact. In both cases there is a local effect of the laser beam. A cellular programming area is preserved around the treated areas, which forms the potential for further skin regeneration. In other words, heat stroke activates new cell growth and metabolic processes in the cells.
The first method of fractional photothermolysis removes microscopic superficial areas of skin cells, strengthens the treated areas in a short time, so the results after the procedure are noticed immediately. Smoothes superficial wrinkles and is therefore considered ideal for eliminating the first signs of age-related skin changes.
The second method of laser impact 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 renewal. 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 within.
It has been proven that the maximum efficiency of fractional photothermolysis is achieved through the combined use of both exposure methods. In this case, the skin will get a double effect - both outside and inside, 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 available.
Efficiency of the procedure
You can make sure that after partial laser rejuvenation your skin becomes even, smooth and radiant after the first procedure. Within a week, the oval of the face will be visibly tightened, wrinkles will be smoothed and the complexion will be smoothed. To consolidate and extend the outcome, a course of procedures at one-month intervals will be required.
With combined partial rejuvenation, the effect of youthful skin is achieved much faster and lasts longer, up to 2-3 years. Of course, the results depend very much on the lifestyle of the individual patient. Quitting bad habits, preventive facial care, a healthy lifestyle, proper and proper sleep help prolong skin youth and prevent the aging and fading process.
The undoubted advantage of the procedure is its painlessness. The specialist uses superficial anesthesia, so that during the procedure, the patient feels only a 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 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, treats it with special medicinal products.
Immediately after the procedure, the skin does not need any additional care. It will take you a little over a week to get back to your normal rhythm of life, while postoperative rehabilitation takes a lot harder and longer.
During the first two days, the face will be swollen, after which it will become slightly red. After 4-7 days, the dead cells will begin to clear, revealing fresh and youthful skin.
Indications for the procedure
If there is any doubt 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:
- Spider veins, stretch marks and marks.
- Enlarged pores. Wrinkles, crow's feet around the eyes.
- Soft, dry and free skin.
Contraindications to the procedure
As with any salon procedure, fractional renewal has a number of contraindications:
- Benign and malignant growths in the treatment area.
- Cancer and ongoing chemotherapy
- Dermatoses and photodermatoses, in the procedure area.
- Herpes infection within a month.
- Acute infectious infections, lack of immunity.
- Chronic diseases such as bleeding disorders, diabetes mellitus, thromboembolic diseases.
- Psoriasis and hypertension.
- History of keloid or vitiligo lesions, family history of vitiligo or keloid.
- Fresh tan, last tanning visit.
- Pregnancy and lactation.
- Retinoid use in the last six months.
Combination of fractional renewal with other procedures
This procedure is always performed only after a prior consultation with a cosmetologist. With marked age-related changes, laser skin reappearance will bring maximum efficiency rather than a fractional rejuvenation method.
In some cases, it will not be possible to do without surgical manipulations, namely endoscopic removal of the face, blepharoplasty or insertion of tightening threads. However, laser rejuvenation will help maintain and increase the effectiveness of the procedures. Will complement their 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.
