The use of lasers in cosmetology has made a real revolution in the field of non-surgical rejuvenation. The painful rehabilitation periods after plastic surgery have long been forgotten, Botox injections, which turn the face into an immobile mask, are a thing of the past. Women have the opportunity to preserve their youth with the help of non-invasive and painless procedures. Beauty still requires sacrifices, but this time they will be purely financial.
What is laser rejuvenation
The skin of the face is perhaps the most vulnerable place to the negative effects of the environment. Atmospheric factors, poor ecology of big cities, poor quality food are external "destroyers". Furthermore, the human face is not a theatrical mask, it "lives". A person talks, eats, laughs, cries, grieves, and generally thrives on emotions. This can only affect the skin: it becomes covered with mimic wrinkles.
Age-related changes are manifested in a gradual loss of elasticity and self-healing ability: the contour of the face is blurred, the eyelids are lowered, nasolabial folds are formed, the corners of the mouth are lowered. An unpleasant photo, right? But it can be "rewritten" with laser rejuvenation. How does the "magic" ray work on aging skin?
In cosmetology, different types of lasers are used, and each of them performs a certain work to correct age-related changes. Indeed, this is a general or point effect on different layers of the skin. Laser rejuvenation technology uses its own wavelength, color spectrum and power for different purposes. The wave can be constant and impulsive.
As a result of selective heat exposure, precisely calibrated damage occurs in the tissues (laser coagulation). In response, the body activates an intensive cellular repair mechanism. In fact, having lost old cells, young and healthy ones "grow" in their place.
Exposure to the deep layers in the laser skin rejuvenation process causes burns, in place of which connective tissue grows from collagen fibers, which acts as a skeleton for the skin and restores its elasticity.
The effectiveness, advantages and disadvantages of laser rejuvenation
Laser rejuvenation has an indisputable advantage over other methods - the result is visible after the first procedure. And this is important, as it instills in a woman the confidence that she is going the right way. The rejuvenation course allows you to look 5-10 years younger.
The advantages of the method:
- replaces complex plastic surgery,
- activates the processes of self-renewal of the skin, stimulating not only external rejuvenation, but also positive processes in the deep layers,
- minimal pain,
- short recovery period.
There are fewer cons than pros, but they are:
- the rejuvenating effect lasts only a few years: from 3 to 5, depending on individual characteristics,
- the laser only deals with fine and medium wrinkles,
- the procedures are expensive.
In cosmetology, laser rejuvenation is considered one of the safest methods of targeting the skin, practically without causing complications, provided it is done correctly.
Types of laser rejuvenation
Cosmetology makes the most of laser for rejuvenation and offers a wide variety of procedures. In general, they are all divided according to the degree of impact into two categories:
- non-ablative, i. e. non-damaging to the skin,
- ablative, damaging the skin.
There are types of procedures in which the skin is only partially damaged.
The term "ablation" refers to the destruction of tissue by radiation, which occurs during laser resurfacing. This is the most painful procedure ever performed with a laser.
In the process of laser skin treatment, the surface layer is subsequently evaporated, leaving an open bleeding surface. The operation is performed under local anesthesia. As a result, the patient receives:
- complete restructuring of the upper layer of the skin,
- elimination of scars and scars,
- smoothing of wrinkles, even partially deep,
- face lifting.
Grinding is performed with an erbium and carbon dioxide (CO2) laser. It has significant disadvantages:
- risk of infection,
- possible pigmentation disorder.
Unlike grinding, the damage during fractional thermolysis is not total. With the help of a laser pulse, microscopic incisions are made on the skin in strictly defined places. Only 15% of the treated surface is damaged. Erbium and carbon dioxide lasers are also used for thermolysis.
Fractional thermolysis does not leave bleeding wounds, but the effect of its application is no worse than that of resurfacing: it tightens sagging skin and evens out its relief. Thermolysis is used in patients with thin skin and for eyelid correction. Fraxel, as it is also called fractional thermolysis, effectively removes age spots.
Another type of fractional exposure is photothermolysis, which cosmetologists call the "gold standard" of laser rejuvenation. The DOT technology is a point effect with a beam that heats the skin up to 40 ° C. At the same time, changes occur in the tissues surrounding these points.
Photothermolysis is considered a complete replacement for blepharoplasty - a safe and effective eyelid lift occurs.
IPL for deep thermolifting
The laser, along with other hardware techniques, is successfully used for deep lifting. The ray penetrates into the deep layers of the skin and heats the tissues at a certain power. Their controlled damage triggers a reaction in the form of increased collagen and elastin production. Outwardly, this manifests itself in the form of tight skin and clear facial contours.
Termolifting is used for:
- cheekbones, cheeks and chin lifts,
- elimination of puffiness under the eyes (at the same time removes dark circles),
- the alignment of the nasolacrimal sulcus and the fight against fine wrinkles around the eyes,
- smoothing of the nasolabial folds.
Termolifting refers to non-ablative methods of exposure.
3D rejuvenation is a modern laser exposure method, which includes three stages:
- The beautician corrects all visible defects: scars, pigmentation, enlarged pores, dark circles.
- Thermolifting of problem areas is carried out.
- The skin is smoothed with a gentle laser treatment.
To achieve the desired effect, a 3D rejuvenation cycle is usually sufficient.
4D rejuvenation is a laser procedure that is performed on a special FOTONA device, which includes erbium and neodymium lasers. Their combination provides an effect on both the surface and the deep layers of the skin. 4D rejuvenation is a patented technology and includes 4 stages:
- SmothLiftin is an effect on the inside of the cheeks through the oral cavity. As a result, they are stiffened due to the remodeling of collagen fibers, internal wound healing, and facial contour correction. The effect is similar to filler injections, but lasts longer.
- FRAC3 - facial surface treatment to eliminate visible defects: pigmentation and scars. Result: smoothing the relief and color of the skin, increasing the tone, eliminating vascular networks.
- PIANO - deep effect of heat to stimulate the metabolic processes of the skin. In fact, this is the thermal lift of the deep laser.
- SupErFicia is a finishing treatment that gives the skin a final smoothness, a matte finish and tightens the pores.
All four phases take place in one session and last about an hour and a half. The method is used in a wide age group: from 27 to 67 years.
Carbon laser peeling
Carbon peeling with a laser is one of the most gentle procedures of its kind. Its task is to cleanse the face of dead skin and start the cell regeneration process. It combines the action of a laser beam and a special carbon gel that is applied to the face. How peeling works:
- The carbon nanogel adheres to dead scales, removing excess fat from the skin and clogged sebaceous plugs in the pores,
- A short laser flash vaporizes the gel, breaking it down into two components: CO2 and water. At this time, the pores of the skin are freed of their contents, "throwing" all the "dirt" on the surface. The process can be compared to a micro-explosion.
- A further action of the laser, thanks to which collagen synthesis is stimulated, occurs on the deeper layers of the skin.
Carbon gel also has an antibacterial effect on the skin. It prevents the development of infections and kills existing pathogenic microorganisms. In addition, it restores the water and acid-base balance of the skin.
Biorevitalization is a term well known to beauty salon regulars. It usually involves injecting hyaluronic acid into the skin. The laser version of this procedure is also effective, but less painful and belongs to non-invasive rejuvenation methods.
Hyaluronic acid is a substance that our skin begins to seriously lack after 30 years. In many ways, skin aging is due to its low content in the body. Creams with hyaluronic acid have a temporary effect that lasts only during the period of use of the cosmetic product.
Laser biorevitalization allows hyaluronic acid molecules to penetrate into the deep layers of the skin, attract and retain moisture in it, stimulating the synthesis of collagen and elastin. The gel for biorevitalization, in addition to the acid itself, contains a substance that suppresses the activity of an enzyme that destroys it when it enters the body.
During the procedure, a gel with low molecular weight hyaluronic acid is applied to the skin, which is then processed with a laser with a special nozzle. Effect of the procedure:
- the skin is hydrated and firmer,
- fine wrinkles are smoothed out,
- the contour of the face is tight,
- reduced swelling and pigmentation under the eyes,
- the skin tone is uniform.
Laser biorevitalization is used to prepare the skin for more serious cosmetic procedures: chemical peels, plastic surgery, and so on.
Indications and contraindications
Laser rejuvenation is indicated for those who are beginning to fade or have significant skin defects:
- wrinkles of different origins,
- dull complexion
- gravitational ptosis,
- blurred oval of the face,
- scarring defects of the skin,
- altered pigmentation
- swelling under the eyes.
Some laser treatments can also be performed on teenagers to eliminate the effects of acne. In general, the aging mechanism in humans begins at around 25 years of age. But for all it proceeds at its speed, due to many factors.
Today, cosmetologists urge, when deciding on the use of laser rejuvenation, to focus not so much on age, but on the condition and needs of the skin.
Like any external effect on the body, laser rejuvenation has a number of contraindications. They can be absolute and temporary. Medical contraindications are absolute:
- tumor processes,
- skin diseases
- blood diseases,
- infectious and viral diseases,
- psychic deviations,
- diseases of the heart and blood vessels.
Temporary contraindications include:
- the presence of herpetic eruptions in the affected area,
- pregnancy and breastfeeding,
- fresh tan,
- a recent chemical peel.
Preparation for the procedure and skin care afterwards
Special preparation for laser rejuvenation is not required, however, cosmetologists give some recommendations, which should not be done 2-3 days before the procedure:
- apply makeup,
- do face cleansing.
Usually, a fractional thermolysis session (the most common type of laser rejuvenation) lasts about an hour. After its completion, a regenerating protective cream is applied to the face. Additionally, the patient receives a skin care reminder during the rehabilitation period.
After the procedure, you will feel a burning sensation on the skin for 1-2 hours. The redness and swelling go away in about 1-3 days.
Recommendations after laser rejuvenation:
- for early healing, it is recommended to use ointments with dexpanthenol and antibacterial components that prevent infection,
- after the redness has passed, you can use creams with hyaluronic acid,
- regardless of the season, when you go out, you need to apply sunscreen to your face,
- it is better to postpone water activities in the form of a swimming pool or sauna for a while, and you can wash and shower on the day of the procedure.
After a competently performed laser rejuvenation procedure, there are almost no negative consequences. If the swelling lasts longer than expected, it can be reduced by reducing fluid intake and using hyaluronic masks.
Itching and rashes may indicate individual allergies or intolerances to the components of the drugs or products used during the procedure. Such manifestations can also be observed in young people with vascular dystonia.
The consequences can be small scars or a protruding vascular network. Nothing can be done with them, but over time they will become barely noticeable. The standard rehabilitation period is 14 days. If the skin has not recovered during this time, it can be helped with vitamins, diet and sun protection.
As with any hardware cosmetology procedure, laser rejuvenation should be approached carefully: taking into account contraindications and financial capabilities (the course of procedures can be quite expensive). Despite mixed reviews, beauticians believe laser technology is the future of the beauty industry.
