Laser procedures aimed at rejuvenating the skin and eliminating signs of aging are increasingly widespread in cosmetology.Due to its high efficiency and safety, a relatively simple and short recovery period, laser treatment gradually moves other methods of skin controlled damage, as, for example, in medium and surface chemical peels.We pay your attention to an overview of the laser correction of age and photos manifestations.
What is aging
An aging in biology is a process of progressive violation and loss of important functions of the body or its parts, in particular, the ability to reproduce and regenerate.In terms of skin, aging manifests itself by the accumulation of genetic defects in cells, which violates the process of division and differentiation. These genetic disorders become reason:
- slimming of the dermal-epidermal joint;
- violations of the barrier function of the skin;
- Increase the loss of transversal humidity with the development of dry skin.
The consequence of internal disorders is the formation of external manifestations of aging - ptose, wrinkles and skin folds.The aging process is irreversible, but cosmetology has means for the prevention of age -related changes.Premature aging is mainly the start of the photo.Under the influence of ultraviolet radiation, it occurs:
- violation of the cellular differentiation process;
- unequal distribution of melanocytes;
- thickening of the cornea stratum (hyperkeratosis);
- Microfing and skin color.
It also violates the state of irrational nutrition of the body, insufficient water consumption, bad habits and unfavorable environmental factors.
Basic morphological types of aging
Based on the external external signs in force of age -related skin changes, 5 main aging types are distinguished:
- Finely wrinkled type. Its main manifestations: a pronounced vascular model, a large number of small wrinkles all over the face, which manifest themselves in statistics, without muscle participation.
- Muscle type. It is characteristic of residents of Central Asia, in which the facial muscles are well developed, and a layer of subcutaneous fatty fabric is thin.This type is characterized by the appearance of nasolabial folds, the softness and the vagueness of the oval of the face.The wrinkles are like a great rupture of the skin.They are deep, which are clearly visible in static.
- Style by type of gravitational ptose. Characteristic for owners of oily skin with a large number of sebaceous glands.The oval changes due to the fact that the fatty bags of the face are offset after the skin.Bryli, the second chin, the big folds appear.
- City by type of tired face. It is expressed by a decrease in the elasticity of soft tissue, pasta, swelling.Nezoglyny folds are clearly visible, the corners of the mouth have come down.
- Mixed type.A combination of gravitational ptose, tired face and small wrinkles.It occurs more often than all other types.
Methods of combating skin aging in modern cosmetology
All the methods used to eliminate aesthetic imperfections from the skin can be divided into three main groups: material, injectable and care procedures.The aesthetic methods that improve the state of the epidermis suggest:
- Use of professional cosmetics;
- Driving surface chemical peels and care procedures.
The injection cosmetology includes five main directions:
- stimulation by injection of the synthesis of collagen and elastin;
- Biorevitalization;
- BIO repair;
- Volumetric correction of the filling based on hyaluronic acid;
- Work with muscle frame - toxin botulinum justo.
Material cosmetology:
- laser rejuvenation;
- Other material effects: Radioifrequencies, microcurrent, wide -band light, ultrasound, myostimulation, etc.
Approaches to rejuvenation
The process of eliminating age -related changes is multi -component.Rejuvenation is not only the launch of neocollagenese.The removal of age or seborrheic keratosis is a rejuvenation.Removing a pronounced vascular mesh is also a rejuvenation.For example, angiogenesis intensifies with age.There are more pathological vessels, they become more visible.By removing these ships, we improve the state and appearance of the face, which visually makes the face younger and more attractive.
Basic laser rejuvenation methods
Rebuilding methods:
- Fractional-CO2 laser;
- non-fractional-co2 laser;
- Erby laser.
Non -dimensional techniques:
- Neodymowe Réjunignage;
- not ablation;
- Cold Alexandrite rejuvenation.
Ablation techniques suggest damage to the skin.These include:
- Classic techniques. They are laser shredders with a complete overlap of 100%.They are generally carried out at the level of the epidermis, no deeper than the basal membrane.
- Fractional. The continuous laser radiation is divided into fractions with a overlap of 5 to 70%.It enters deeper layers of the skin, into the dermis.
The mechanism of action of lasers for rejuvenation
The stimulating effect of laser radiation on the fabric is based on the activation of fibroblasts, of neocollagene.Laser energy, harmful or without damaging the epidermis, tries to reach dermal layers, more often by heating, create such controlled trauma in which all regenerative processes are launched, fibroblasts begin to synthesize the fibers.
Rejuvenation by the CO2 laser
The rejuvenation of CO2 is carried out in violation of the integrity of the skin.This implies prolonged rehabilitation.The Erbium laser does not have such a rejuvenation effect.
Indications:
- Type of aging gravitational ptose;
- Post -acne scars, other scars;
- Small wrinkles;
- Elastosis expressed.
Neodymowe
The neodymium laser is characterized by effects not abroad.The wavelength of 1064 nm allows the radiation to enter deep layers of the skin at the dermis and there, due to heating, to stimulate synthetic processes, the work of fibroblasts.The epidermis is not damaged.The recovery period is not required.Not a single laser procedure can do without rehabilitation, another thing is that the degree of violations of the neodymium radiation is minimal: redness lasts 3 to 6 hours.
Indications:
- Type of aging with small wrinkles;
- Small static wrinkles;
- enlarged pores;
- Unequal complexion.
Cold return Alexandrite
It is carried out on a laser rejuvenation device.The radiation with a wavelength of 755 Nm is mainly absorbed by melanin.This makes an essential cold laser to remove pigmentation and improve skin color.The differences in rejuvenation of cold and other methods are that the photo is mainly used here, not the photo of the thermal effect.In other words, the neocollagenese and the increase in the function of fibroblasts are launched without heating, without thermal damage to the dermis and the epidermis.
Indications:
- pigmentation;
- enlarged pores;
- Post -acne;
- Small wrinkles;
- General decrease in the complexion.
Combined system.The device is equipped with a neodymium laser with a wavelength of 1064 Nm and a cold laser with a wavelength of 755 Nm.
Application areas:
- Elimination of age spots from various etiologies and complexity;
- Uninformed rejuvenation with a complete solution to photo problems starting in a single session without period of rehabilitation;
- Total hair removal of hair of all color, any structure, in all skin types photos;
- Elimination of vascular pathologies, on any part of the body with a diameter of ships up to 4 mm.
The device allows you to define optimal parameters for radiation parameters and the frequency of repetition impulses.Solve five problems for a procedure:
- Hair removal and hair removal on a cold laser;
- Remove for tanning or very shiny hair, elimination of vessels on the face and lower limbs, acne treatment, rejuvenation, biorevitalization of the laser on the neodymium laser.
Elimination of pigments
Only a laser can destroy the pigment in any age, even mature.The peels and creams act more superficially.Excellent results can be obtained in the lower eyelids ("dark circles"), neckline, back, face and hands.The spot immediately after the procedure darkens first, then gradually leaves.On the surface of it for a week of pasture, an abundant peel can be observed, which nevertheless does not violate social interactions.The scales are easily removed during washing and almost invisible after applying a moisturizer.To get rid of pigmentation forever, only 2 to 4 procedures with one interval per month are sufficient.
The procedure is carried out at a sufficiently high speed, that is to say that when you use a high frequency, just pass the pigmented neoplasms twice.This does not require more than 10 to 15 minutes, even if we are talking about hyper pigmentation of the whole face.Cold radiation is absorbed by melanin 50 times more actively than hemoglobin, so no other structure is affected in addition to the age training.The use of such techniques in order to remove age households is extremely undesirable.Here, firstly, we carry out the strongest injury in the skin, and secondly, we warm the tissues and thus actively stimulate the melanocytes.On the one hand, we can eliminate hyper pigmenting, and on the other hand, we actively stimulate melanogenesis.Ablative methods can be used in patients with hyperpigmentation, but only under the coverage of drugs blocking melanogenesis.It can be Hydrochinon or professional funds.
Laser biorevitalization
The gel and the base of hyaluronic acid are applied to the face.Under the influence of a neodymium laser, hyaluronic acid easily penetrates into the deeper layers of the skin, hydration.Laser exposure stimulates the synthesis of collagen and elastin, which still improves the anti-aging effect of the procedure.Thus, you can make effective hydration of the neck, neckline, hands an hour before an important event in life.There are no unpleasant sensations.The duration of the procedure is 15 minutes.Without seasonal restrictions.
Laser rejuvenation on the device
An innovative laser system to eliminate vascular pathologies from any degree of complexity combines two lasers, two lengths of neodymium waves and impulsive laser on dyes.Two wavelengths in multiplex mode can be combined in a single flash.
Areas of application
Treatment of vascular lesions of the face and body in patients with any type of photo skin:
- Treatment of face and lower limbs, varicose veins, hemangiom, rosacea;
- Correction of "wine points".
Elimination of pigmentation, rejuvenation:
- photography;
- Laser care procedure - The "exit" procedure;
- Laser rejuvenction without a perodice of reduction.
Problematic skin treatment: elimination of vascular spots and acne and post-acne pigments.
The scope of laser rejuvenation
To date, the device is the only picosecond laser and fully certified, the first alekship laser in the world, interacting with the patient's skin thanks to a secure mechanical effect.Thanks to the wavelength, the fractional optics (fractional optical network), the diet (photo-mechanical effect) reaches the effect comparable to the roar of CO2 without thermal damage to the epidermis, without rehabilitation.
Application areas:
- rejuvenation;
- withdrawal of tattoos of all color;
- withdrawal of age spots;
- Leather alignment;
- Treatment of melasma;
- The treatment of scars is post-acne.
The mechanism of the mechanical photo effect
When a large number of ultra-powerful impulses in the Picoseconde range, an optical effect induced by the laser is activated.Optical areas induced by the laser are created in the tissues.They look like bubbles located in the epidermis.These bubbles create pressure and a shock wave to the dermis.In the dermis, without any thermal damage, the cytokine cascade, a cellular reaction, during which cells begin to transmit a signal that occurred.Active stimulation of restorative processes occurs.We obtain the result which can be obtained with a significant heating of the tissues, without thermal damage to cells and extracellular structures.
