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 elimination of toxins and toxins and a decrease in the supply of nutrientsto cellular structures. Through 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 laser exposure, part of the cells in the dermis are activated and the other part dies. Typically, dead cells die rather than living cells which have no potential for further recovery.
In the process of weak cell death, the freed 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, 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 several microscopic beams, creating an impact mesh structure on the treatment area. The innovative value of the technology is that the laser works in local areas, which preserves the skin areas intact - they accelerate the regeneration and healing of the skin.
Fractionated thermolysis varieties
Fractional Laser Rejuvenation has been used successfully to tighten and firm skin in one of two possible ways. They differ in the characteristics of the action of the laser, the depth of its penetration and the 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 top dermal layer is exposed.
The second method of treatment affects the lower epidermal and dermal layers, leaving the upper layer of skin intact. In both cases, the laser beam has a local effect. An area of cellular programming is preserved around the treated areas, which constitutes a potential for additional skin regeneration. In other words, heat shock activates the growth of new cells and metabolic processes within the cells.
The first method of fractional photothermolysis removes the superficial microscopic areas of skin cells, tightens the treated areas in a short time, so that the results after the procedure are immediately noticeable. It softens 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 initiates metabolic processes, forms a new membrane framework, activates the production of collagen, the skin becomes younger and regenerates from the inside.
Maximum efficiency of fractional photothermolysis has been proven to be achieved through the combined use of two exposure methods. In this case, the skin will receive a double effect - both exterior and interior, which provides a long-term effect of rejuvenating the skin. 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 make sure that after fractional laser rejuvenation your skin becomes even, smooth and glowing after the first procedure. In a week, the oval of the face will noticeably tighten, wrinkles will be smoothed and the complexion will be unified. To consolidate and extend the result, a course of procedures will be necessary at monthly intervals.
With combined fractional rejuvenation, the effect of youthful skin is much faster and lasts longer, up to 2-3 years. Of course, the results depend a lot on the lifestyle of each patient. Quitting bad habits, preventive facial care, a healthy lifestyle, adequate and adequate sleep help to prolong the youthfulness of the skin and prevent the process of aging and withering.
The undoubted advantage of the procedure is its painlessness. The specialist uses surface anesthesia, so during the procedure the patient only experiences a slight tingling sensation in the affected area.
Progress of the procedure
The undoubted advantage of the procedure is its painlessness. The specialist applies surface anesthesia, therefore, during the procedure, the patient only feels 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, treats him with special drugs.
Immediately after the procedure, the skin does not need additional care. It will take a little over a week to get back to your normal pace of life, while rehabilitation after surgery takes a lot more time and difficulty.
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 cleanse themselves, revealing fresh, youthful skin.
Indications of the procedure
If there are any 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.
- Dilated pores.
- Wrinkles, crow's feet around the eyes.
- Flabby, withered, 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 operation.
- Herpetic infection within a month.
- Acute infectious infections, immunodeficiency.
- Chronic diseases such as coagulation disorders, diabetes mellitus, thromboembolic diseases.
- Psoriasis and hypertension.
- History of keloid scarring or vitiligo, family history of vitiligo or keloids.
- Fresh tan, recent tan visit.
- Pregnancy and breastfeeding period.
- 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 pronounced age-related changes, laser skin resurfacing will provide maximum effectiveness, not a fractional rejuvenation method.
In some cases, it will not be possible to do without surgical manipulations, namely endoscopic lifting, blepharoplasty or the insertion of clamping threads. Nonetheless, laser rejuvenation will help maintain and improve the effectiveness of the procedures. It will complement their results and refine the client's appearance.
Laser rejuvenation methods are perfectly combined with procedures such as mesotherapy and plasma lifting, as well as biorevitalization based on hyaluronic acid.
