The main reason for skin aging is the deterioration of the functional abilities of metabolism and cell growth, as well as the slower removal of toxins and waste and the reduction of the supply of nutrients in cellular structures.Thanks to laboratory studies, it became known that this is a reversible process, that is, that there is always a possibility of increasing cellular activity.Scientists have discovered that after thermal exposure to the laser, one part of the cells in the dermis is activated, while the other part dies.As a rule, dead cells die, not living cells, which have no potential for further renewal.
As weak cells die, the vacated intercellular space is occupied by stronger cells.The thermal effect that occurs after the laser treatment activates cellular activity, restoring cellular renewal and growth.The quality and speed of cellular restoration depends on the diameter of the laser beam.Its thickness must not exceed 200 microns, then the formation of a layer of healthy and young skin will begin on the treated area.
For this reason, the technique of laser rejuvenation 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 treatment area.The innovative significance of the technology is that the laser acts on local areas, thus preserving intact areas of the skin - accelerating the regeneration and healing of the skin.
Types of fractional thermolysis
Fractional laser rejuvenation is successfully used to tighten and strengthen the skin in one of two possible exposure methods.They differ in the characteristics of 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 vaporizing them.In other words, this method exposes only the top layer of skin.
The second mode of action acts on 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 zone of cellular programming is maintained around the treated areas, which creates the potential for further skin renewal.In other words, heat shock activates the growth of new cells and metabolic processes in cells.
The first method of fractional photothermolysis removes the superficial microscopic surfaces of skin cells, tightens the treated areas in a short time, so the results after the procedure are visible immediately.It perfectly smoothes surface wrinkles, so it is considered an ideal remedy for removing the first signs of age changes on the skin.
Another method of laser action is suitable for solving problems deep in the skin, when the aging process is no longer reversible.This method is a kind of "heavy artillery" of laser rejuvenation.Affecting the deep layers of the epidermis and dermis, the laser triggers metabolic processes, forms a new membrane frame, activates collagen production, so the skin becomes younger and regenerates from the inside.
It has been proven that the maximum efficiency of fractional photothermolysis is achieved by the combined use of two exposure methods.In this case, the skin will receive a double effect - both externally and internally, which provides a long-lasting effect of skin rejuvenation.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 ensure 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 be noticeably tightened, wrinkles will be smoothed out, and the complexion will be even.To consolidate and prolong the result, a course of procedures will be required at monthly intervals.
With combined fractional rejuvenation, the effect of youthful skin is achieved much faster and lasts longer, up to 2-3 years.Of course, the results depend to a large extent on the individual patient's lifestyle.Renunciation of bad habits, preventive facial care, healthy lifestyle, regular and adequate sleep contribute to prolonging the youth of the skin and preventing the aging and fading process.
The undoubted advantage of the procedure is its painlessness.The specialist uses surface anesthesia, so that during the procedure the patient feels only a slight tingling sensation in the affected area.
Progress of the procedure
The undoubted advantage of the procedure is its painlessness.The specialist uses surface anesthesia, so that during the procedure the patient feels only a slight tingling sensation in the affected area.The anesthetic is applied immediately before the start of the session, which can last up to an hour - it all depends on the treatment area.
After the procedure, the specialist advises the client on the necessary skin care and treats it with special medicines.
Immediately after the procedure, the skin does not require additional care.It will take you a little more than a week to return to the normal rhythm of life, while rehabilitation after surgery takes much more difficult and longer.
The face will be swollen for the first two days, after which it will turn red.Within 4-7 days, dead cells will begin to slough off, revealing fresh and youthful skin.
Indications for the procedure
If there are doubts about the effectiveness of fractional laser rejuvenation, then it is worth first visiting the procedure 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.
- Loose, aged and flabby skin.
Contraindications for the procedure
Like any salon procedure, fractional rejuvenation has a number of contraindications:
- Benign and malignant formations in the treatment zone.
- Oncological diseases and continuous chemotherapy.
- Dermatoses and photodermatoses in the affected area.
- Herpes infection that appeared within a month.
- Acute infectious infections, immunodeficiency.
- Chronic diseases, for example, bleeding disorders, diabetes mellitus, thromboembolic diseases.
- Psoriasis and hypertension.
- History of keloid or vitiligo, family history of vitiligo or keloid.
- Freshly tanned, recent visit to the solarium.
- Period of pregnancy and breastfeeding.
- 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.In the case of obvious age-related changes, the maximum effect will be achieved by laser skin resurfacing, not fractional rejuvenation.
In some cases, it will not be possible without surgical manipulations, i.e. endoscopic facelift, blepharoplasty or the introduction of tightening threads.However, laser rejuvenation will help maintain and improve the effectiveness of the procedures.It will complement their results and perfect the look of the client.
Procedures such as mesotherapy and plasma lifting, as well as biorevitalization based on hyaluronic acid, are perfectly combined with laser rejuvenation techniques.
