Laser procedures destined to rejuvenate the skin and eliminate signs of aging are increasingly widespread in cosmetology.Due to its high efficiency and safety, a relatively simple and short recovery period, laser therapy gradually displaces other methods of skin controlled damage, such as, in the average and average chemical shells of the surface.We carry out an overview of the devices for the laser correction of the manifestations of age and photographic.
That is to get older
A biology aging is a process of gradual rape and loss of important body or its parts, in particular, the ability to reproduce and regeneration.At the skin level, aging is manifested by the accumulation of genetic defects in cells, which violate the division and differentiation process. These genetic disorders become reason:
- Landwash of dermal-epidermal articulation;
- violations of the skin barrier function;
- Increase the loss of transepidermal humidity with the development of dry skin.
The consequence of internal disorders is the formation of external manifestations of aging: ptosis, wrinkles and wrinkles of the skin.The aging process is irreversible, but cosmetology has means for the prevention of age -related changes.Premature aging is mainly that the photo begins.Under the influence of ultraviolet radiation, it occurs:
- violation of the cell differentiation process;
- unequal distribution of melanocytes;
- thickening of the stratum corneo (hyperkeratosis);
- Microfing and skin color.
It also violates the state of irrational nutrition of the body, insufficient use of water, bad habits and adverse environmental factors.
Basic morphological types of aging
According to the external signs prevailing from age -related skin changes, 5 main types of aging are distinguished:
- Finely wrinkled guy. Its main manifestations: a pronounced vascular pattern, a large number of small wrinkles throughout the face, which are manifested in statistics, without muscle participation.
- Muscle type. It is characteristic of the residents of Central Asia, in which the facial muscles are well developed, and a layer of subcutaneous fatty tissue is thin.This type is characterized by the appearance of nasolabial folds, the softness and confusion of the oval of the face.Wrinkles seem to break the big skin.They are deep, which are clearly visible in statistics.
- Type of gravitational ptosis type. Characteristic for grease leather owners with a large number of sebaceous glands.Oval changes due to the fact that the fat bags move after the skin.Bryli, the second chin, large folds appear.
- City by tired face. It is expressed by a decrease in the elasticity of soft tissues, pasta, swelling.Nezogly folds are clearly visible, the corners of the mouth descend.
- Mixed type.A combination of gravitational ptosis, tired face and small wrinkles.Occurs more frequently than all other types.
Methods to combat skin aging in modern cosmetology
All methods used to eliminate aesthetic imperfections of the skin can be divided into three main groups: hardware, injectables and attention procedures.The aesthetic methods that improve the state of the epidermis suggest:
- use of professional cosmetics;
- Performing surface chemical shells and attention procedures.
The cosmetology of the injection includes five main directions:
- Injection stimulation of collagen and elastin synthesis;
- Biorevitization;
- biological repair;
- Volumetric correction of the landfill based on hyaluronic acid;
- Work with the muscle frame: Just Botulinic Toxin.
Hardware cosmetology:
- laser rejuvenation;
- Other hardware effects: radiofrequency lifting, microcurrent, broadband light, ultrasound, myosimulation, etc.
Approaches to rejuvenation
The process of eliminating age -related changes is multicomponent.Rejuvenation is not just the launch of Neocolagénesis.Eliminating points of age or seborrheic keratosis is rejuvenation.Eliminating a pronounced vascular mesh is also a rejuvenation.For example, angiogenesis intensifies with age.There are more pathological vessels, they become more notable.By eliminating these glasses, we improve the condition and appearance of the face, which visually makes the face younger and more attractive.
Basic methods of laser rejuvenation
Ablation methods:
- fractional laser-CO2;
- No fractional laser-CO2;
- Erby Laser.
Non -dimensional techniques:
- Neodymowe rejuvenation;
- no ablation;
- Alexandrite's cold rejuvenation.
Ablation techniques suggest damage to the skin.These include:
- Classic techniques. These are laser grilles with a complete overlap of 100%.In general, they are carried out at the epidermis level, not deeper than the basal membrane.
- Fractional. Continuous laser radiation is divided into fractions with an overlap of 5 to 70%.Penetrates the deepest layers of the skin, in the dermis.
The mechanism of action of the lasers for rejuvenation
The stimulating effect of laser radiation in the tissue is based on the activation of fibroblasts, neocolagénesis.The energy of the laser, harmful or without damaging the epidermis, tries to reach the dermal layers, more frequently by heating, creates such a controlled trauma in which all the regenerative processes are launched, the fibroblasts begin to synthesize the fibers.
CO2 laser rejuvenation
CO2 rejuvenation is carried out in violation of skin integrity.It implies prolonged rehabilitation.The Erbium laser does not have such rejuvenation effect.
Indications:
- Type of aging of gravitational ptosis;
- Scars of the publication -acne, other scars;
- small wrinkles;
- Expressed elastosis.
Neodymowe rejuvenation
The neodymium laser is characterized by effects not along the way.The wavelength of 1064 Nm allows the radiation to go to deep skin layers at the level of 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 dispense with rehabilitation, another thing is that the degree of neodymium radiation violations is minimal: hard redness of 3 to 6 hours.
Indications:
- type of aging with small wrinkles;
- small static wrinkles;
- expanded pores;
- Unequal complexion.
Alexandrita's cold rejuvenation
It is carried out in a laser rejuvenation device.Radiation with a 755 nm wavelength is predominantly absorbed by melanin.This makes a cold laser indispensable to eliminate pigmentation and improve skin color.The differences in cold rejuvenation and other methods are that the photo is mainly used here, and not the photo effect photo.That is, neocolagénesis and the increase in the function of fibroblasts are thrown without heating, without thermal damage to the dermis and the epidermis.
Indications:
- pigmentation;
- expanded pores;
- post -acne;
- small wrinkles;
- General decrease in skin tone.
Combined system.The device is equipped with a neodymium laser with a 1064 nm wavelength and a cold laser with a 755 nm wavelength.
APPLICATION AREAS:
- Elimination of age points of various etiologies and complexity;
- Rejuvenencia notable with an integral solution to the problems of the photo that begin in a session without a rehabilitation period;
- The total elimination of the hair of any color, any structure, in all photos of skin types;
- Eliminating any vascular pathologies, anywhere in the body with a diameter of the container of up to 4 mm.
The device allows you to establish optimal settings for radiation parameters and the frequency of repetition pulses.Solve five problems for a procedure:
- hair removal and elimination of a cold laser;
- Remove for the tan or very bright hair, the elimination of the vessels in the face and the lower extremities, the treatment of acne, rejuvenation, biorevitalization laser in the neodymium laser.
Pigment removal
Only a laser can destroy the pigment at any age, even mature.The shells and creams act more superficially.Excellent results can be obtained on the lower eyelids ("dark circles"), neckline, back, face and hands.The place immediately after the procedure is darkened first, and then gradually.On the surface during a week pasta, abundant peeled can be observed, which, however, does not violate social interactions.The scales are easily eliminated when they are washed and are almost invisible after applying a moisturizer.To get rid of pigmentation forever, only 2-4 procedures with an interval per month are enough.
The procedure is carried out at a sufficiently high speed, that is, when a high frequency is used, it is sufficient to pass pigmented neoplasms twice.This does not require more than 10-15 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 age formation.The use of such techniques to eliminate age foci is extremely undesirable.Here, in the first place, we make the strongest skin lesion and, secondly, we heat the tissues and, therefore, actively stimulate melanocytes.On the one hand, we can eliminate hyper pigmentation and, on the other, we actively stimulate melanogenesis.Ablative methods can be used in patients with hyperpigmentation, but only under the coverage of medications that block melanogenesis.It can be hydrochinon or professional line of funds.
Laser biorevitalization
The gel and the base of hyaluronic acid apply to the face.Under the influence of a neodymium laser, hyaluronic acid easily penetrates the deepest layers of the skin, moisturizing.Laser exposure stimulates collagen and elastin synthesis, which further improves the anti -enhancement effect of the procedure.Therefore, you can make effective neck hydration, neckline, hands an hour before an important event in life.There are no unpleasant sensations.The duration of the procedure is 15 minutes.No seasonal restrictions.
Laser rejuvenation on the device
An innovative laser system to eliminate vascular pathologies of any complexity of complexity combines two lasers, two neodymium wavelengths and impulsive laser in dyes.Two wavelengths can be combined in multiplex mode in a flash.
Areas of application
Treatment of vascular lesions of the face and body in patients with any type of skin:
- Teangiectasia treatment of the face and lower extremities, varicose veins, hemangiom, rosacea;
- Correction of "wine points".
Pygmentation elimination, rejuvenation:
- photograph;
- Laser Attention Procedure: the "output" procedure;
- Laser rejuvenation without a rehabilitation period.
Problematic skin treatment: Elimination of vascular and pigmentary spots from acne and post -acné.
The scope of laser rejuvenation
To date, the device is the only one and totally laser certificate of Picosegondos, the world's first Alekship laser, which interacts with the patient's skin through a safe mechanical effect.Thanks to the wavelength, the fractional optics (fractional optical matrix), the regime (photo-mechanical effect) achieves the effect comparable to the CO2 alliance without thermal damage to the epidermis, without rehabilitation.
APPLICATION AREAS:
- rejuvenation;
- elimination of tattoos of any color;
- Elimination of age spots;
- leather alignment;
- Melasma treatment;
- The treatment of scars is post -acne.
THE MECHANISM OF THE MECHANICAL EFFECT
When a large number of ultra enhanced pulses are activated in the range of peaks, a laser -induced optical effect is activated.Laser -induced optical areas are created in fabrics.They look like bubbles located inside the epidermis.These bubbles create pressure and shock wave towards the dermis.In the dermis, without any thermal damage, the cytokine waterfall, a cell reaction, during which the cells begin to transmit a signal that the damage occurred.Active stimulation of repair processes occurs.We obtain the result that can be achieved with significant warming of tissues, without thermal damage to extracellular cells and structures.
