The main reason for skin aging is the deterioration of the functional capacity of metabolism and cell growth, as well as the slowing down of the removal of toxins and toxins and the reduction of the supply of nutrients to cellular structures. Thanks to laboratory studies, it has become known that this is a reversible process, ie there is always the possibility of activating cellular activity. Scientists have discovered 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, not living cells that have no potential for further recovery.
In the process of weak cell death, the emptied intercellular space is occupied by stronger cells. The thermal effect that appears after the laser treatment activates cell activity, restoring cell growth. The quality and speed of cell repair depend 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 on the treated area.
For this reason, the laser rejuvenation technique has been improved by 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 processing area. The innovative value of the technology lies in the fact that the laser acts on local areas, thus preserving intact areas of the skin - accelerating skin regeneration and healing.
Types of fractional thermolysis
Fractional laser rejuvenation is successfully used to tighten and tighten 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 on certain areas.
The first method of action - fractional photothermolysis - affects the upper cells of the epidermis, literally evaporating them. In other words, only the upper dermal layer is exposed to this method.
The second method of treatment affects the lower epidermal and dermal layers, and the upper layer of the skin remains intact. In both cases, the laser beam has a local effect. A cell programming zone has been preserved around the treated areas, which creates 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 parts of the skin cells, tightens the treated areas in a short time, so that the results are immediately visible after the procedure. It smoothes surface wrinkles and is therefore considered ideal for removing the first signs of age-related changes in the skin.
Another method of laser exposure is suitable for solving problems deep in the skin, when the aging process is already irreversible. This method is a type of "heavy artillery" of laser rejuvenation. By acting on the deep layers of the epidermis and dermis, the laser initiates metabolic processes, forms a new membrane framework, activates collagen production, so that the skin becomes younger and regenerates from within.
It has been proven that the maximum efficiency of fractional photothermolysis is achieved by the combined use of two methods of exposure. In this case, the skin will get 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.
Process efficiency
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 face will noticeably tighten, wrinkles will flatten out, and the complexion will even out. A course of procedures at one-month intervals will be required to consolidate and expand the result.
Combined fractional rejuvenation achieves the effect of youthful skin much faster and lasts longer, up to 2-3 years. The results, of course, depend a lot on the lifestyle of the individual patient. Cessation of bad habits, preventive facial care, healthy lifestyle, proper and correct 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 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, so during the procedure the patient feels only slight tingling in the affected area. The anesthetic is applied shortly before the start of the session, which can last 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 medications.
Immediately after the procedure, the skin does not need additional care. It will take you a little over a week to get back to your normal rhythm of life, while rehabilitation after surgery takes a lot harder and longer.
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, revealing fresh and youthful skin.
Indications for 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, of which there are many:
- Acne.
- Pigmentation.
- Spider veins, stretch marks and scars.
- Enlarged pores.
- Wrinkles, crow's feet around the eyes.
- Hanging, withered and sagging 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 keloid.
- Fresh tanned skin, a recent visit to the sunshade.
- Pregnancy and lactation.
- Retinoid use in the last six months.
Combination of fractional rejuvenation with other methods
This procedure is always performed only after a preliminary consultation with a cosmetologist. With pronounced age-related changes, laser skin rejuvenation will bring maximum efficiency rather than a fractional rejuvenation method.
In some cases, it will not be possible without surgical manipulations, ie endoscopic facelift, blepharoplasty or the introduction of tightening. However, laser rejuvenation will help maintain and increase the efficiency of the procedure. It will complement their results and improve the appearance of the client.
Laser rejuvenation methods combine perfectly with procedures such as mesotherapy and plasma lifting, as well as biorevitalization based on hyaluronic acid.
