The main cause of skin aging is the deterioration of the functional abilities of metabolism and cell growth, as well as slowing down the removal of toxins and toxins and reducing the supply of nutrients in 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 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, not living cells, which have no potential for further recovery.
In the process of death of weak cells, the freed intercellular space is occupied by stronger cells. The thermal effect that occurs 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 be more than 200 microns, then in the treated area will begin to form a layer of healthy and young skin.
For this reason, the laser rejuvenation technique has been improved with the introduction of fractional thermolysis. In this process, the laser beam splits 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 the intact skin areas - they accelerate the regeneration and healing of the skin.
Varieties 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 epidermal cells, literally evaporating them. In other words, only the upper dermal layer is exposed in this method.
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. A cell programming area 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 the cells.
The first method of fractional photothermolysis removes surface microscopic areas from skin cells, tightens the treated areas for a short time, so that the results after the procedure are noticeable immediately. It smoothes surface wrinkles and is therefore considered ideal for removing the first signs of age-related skin changes.
The second method of laser exposure 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. By acting on the deep layers of the epidermis and dermis, the laser begins metabolic processes, forms a new membrane framework, activates collagen production, so that the skin becomes younger and regenerates from within.
It has been shown that the maximum efficiency of fractional photothermolysis is achieved by the combined use of two exposure methods. In this case, the skin will get a double effect - both outside and inside, which provides a long-term effect of skin rejuvenation. Such equipment is used by a huge number of modern medical institutions that have modern laser equipment.
Efficiency of the procedure
You can be 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 and the complexion will be evened out. A course of procedures at monthly intervals will be required to consolidate and extend the result.
With combined fractional rejuvenation, the effect of skin youth is achieved much faster and lasts longer, up to 2-3 years. Of course, the results depend a lot on the lifestyle of the individual patient. The cessation of bad habits, preventive facial care, healthy lifestyle, proper and proper sleep help to prolong the youth of the skin and prevent the process of aging and fading.
Undoubted advantage of the procedure is its painlessness. The specialist uses superficial anesthesia, so that during the procedure the patient feels only a slight tingling in the affected area.
Procedure progress
Undoubted advantage of the procedure is its painlessness. The specialist applies superficial anesthesia, due to which during the procedure the patient feels only a 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 drugs.
Immediately after the procedure, the skin does not need additional care. It will take you a little over a week to return to your normal rhythm of life, while rehabilitation after surgery takes much harder and longer.
For the first two days, the face will be swollen and then slightly red. After 4-7 days, the 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 start according to the indications, which are many:
- Acne.
- Pigmentation.
- Spider veins, stretch marks and scars.
- Enlarged pores.
- Wrinkles, crow's feet around the eyes.
- Sagging, dry and sagging skin.
Contraindications to the procedure
As with any salon procedure, fractional rejuvenation has a number of contraindications:
- Benign and malignant tumors in the field of treatment.
- Cancer and ongoing chemotherapy
- Dermatoses and photodermatoses, in the field 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 tan visit.
- Pregnancy and lactation.
- Retinoid use in the last six months.
Combination of fractional rejuvenation with other procedures
This procedure is always performed only after prior consultation with a cosmetologist. With pronounced age-related changes, laser skin rejuvenation will bring maximum effectiveness, not a method of fractional rejuvenation.
In some cases it will not be possible without surgical procedures, namely endoscopic facelift, blepharoplasty or insertion of sutures. Nevertheless, laser rejuvenation will help maintain and increase the effectiveness of procedures. This will complement their results and improve the appearance of the client.
Laser rejuvenation methods are perfectly combined with procedures such as mesotherapy and plasma lifting, as well as biorevitalization based on hyaluronic acid.
