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 therapy gradually displaces other methods of controlled damage to the skin, such as, for example, in the middle and surface-average chemical peels.We bring to your attention an overview of devices for laser correction of the manifestations of age and photoaging.
What is aging
A aging in biology is a process of gradual violation and loss of important functions of the 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 process of division and differentiation. These genetic disorders become the reason:
- thinning of dermal-epidermal joint;
- violations of the barrier function of the skin;
- Increase transepidermal moisture loss with the development of dry skin.
The consequence of internal disorders is the formation of external manifestations of aging - ptosis, wrinkles and skin creases.The aging process is irreversible, but cosmetology has means for the prevention of age -related changes.Premature aging is primarily photo starting.Under the influence of ultraviolet radiation, it occurs:
- violation of the process of cell differentiation;
- uneven distribution of melanocytes;
- thickening of the stratum corneum (hyperkeratosis);
- Microfing and the color of the skin.
It also violates the state of the body irrational nutrition, insufficient water use, bad habits and adverse environmental factors.
Basic morphological types of aging
Based on the prevailing external signs of age -related skin changes, 5 main types of aging are distinguished:
- Finely wrinkled type. Its main manifestations: a pronounced vascular pattern, a large number of small wrinkles throughout the face, which manifest in statics, 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 tissue is thin.This type is characterized by the appearance of nasolabial folds, the smoothness and fuzziness of the oval of the face.Wrinkles look like large skin breaking.They are deep, which are clearly visible in statics.
- Style by type of gravitational ptosis. Characteristic for owners of oily skin with a large number of sebaceous glands.The oval changes due to the fact that fat bags of the face are shifted down after the skin.Bryli, the second chin, large folds appear.
- Town by type of tired face. It is expressed by a decrease in the elasticity of soft tissues, pastes, swelling.Nezoglyny folds are clearly visible, the corners of the mouth are descended down.
- Mixed type.A combination of gravitational ptosis, tired face and small wrinkles.It occurs more often than all other types.
Methods of combating skin aging in modern cosmetology
All methods that are used to eliminate aesthetic imperfections of the skin can be divided into three main groups: hardware, injectable and care procedures.Aesthetic methods that improve the state of the epidermis suggest:
- use of professional cosmetics;
- Conducting surface chemical peels and care procedures.
Injection cosmetology includes five main directions:
- injection stimulation of collagen and elastin synthesis;
- biorevitalization;
- bio reparation;
- volumetric correction of hyaluronic acid -based filler;
- Working with muscle frame - Botulinum Toxin Justo.
Hardware cosmetology:
- laser rejuvenation;
- Other hardware effects: radio frequency lifting, microcurrents, broadband light, ultrasound, myostimulation, etc.
Approaches to rejuvenation
The process of eliminating age -related changes is multicomponent.Rejuvenation is not only the launch of De Neocollagenesis.Removing age spots or seborrheic keratosis is rejuvenation.Removing a pronounced vascular mesh is also a rejuvenation.For example, angiogenesis intensifies with age.There are more pathological vessels, they become more noticeable.Removing these vessels, 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-CO2 laser;
- not fractional-CO2 laser;
- Erby laser.
Non -dimensional techniques:
- neodymowe rejuvenation;
- not ablation;
- Cold Alexandrite rejuvenation.
Ablation techniques suggest damage to the skin.These include:
- Classical techniques. These are laser grinders with a full 100%overlap.They are usually carried out at the epidermis level, not deeper than the basal membrane.
- Fractional. Continuous laser radiation is divided into fractions with an overlap from 5 to 70%.It penetrates into 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, De neocollagenesis.The energy of the laser, damaging or without damaging the epidermis, tries to reach the dermal layers, more often by heating, create such a controlled trauma in which all regenerative processes are launched, fibroblasts begin to synthesize the fibers.
Rejuvenation by laser CO2
CO2 rejuvenation is carried out in violation of the integrity of the skin.It involves prolonged rehabilitation.The erbium laser has no such effect of rejuvenation.
Indications:
- aging type of gravitational ptosis;
- scars of the post -acne, other scars;
- small wrinkles;
- Expressed elastosis.
Neodymowe rejuvenation
The neodymium laser is characterized by non -abroad effects.The wavelength of 1064 Nm allows radiation to go into deep layers of the skin to the level of the dermis and there, due to the 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 neodymium radiation is minimal: redness lasts 3-6 hours.
Indications:
- type of aging with small wrinkles;
- small static wrinkles;
- expanded pores;
- Uneven complexion.
Cold Alexandrite rejuvenation
It is carried out on a laser rejuvenation apparatus.Radiation with a wavelength of 755 Nm 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 of the thermal effect.That is, Neocollagenesis and the increase in the function of fibroblasts are launched without heating, without thermal damage to the dermis and 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 wavelength of 1064 Nm and a cold laser with a wavelength of 755 Nm.
Areas of application:
- removal of age spots of various etiologies and complexity;
- non -able rejuvenation with a comprehensive solution to the problems of photo starting in one session without a rehabilitation period;
- total hair hair removal of any color, any structure, in all photos of skin types;
- Removing any vascular pathologies, on any part of the body with a vessel diameter of up to 4 mm.
The device allows you to set optimal settings for radiation parameters and the frequency of repeating pulses.Solving five problems for one procedure:
- hair removal and removal on a cold laser;
- Remove for tanning or very bright hair, removal of vessels on the face and lower extremities, treatment of acne, rejuvenation, laser biorevitalization on the Neodymium laser.
Pigment removal
Only a laser can destroy the pigment in any, even mature age.Peels and creams act more superficially.Excellent results can be obtained in the lower eyelids (“dark circles”), neckline, back, on the face and hands.The spot immediately after the procedure first darkens, and then gradually leaves.On the surface of it during a week-pasture, abundant peeling can be observed, which, nevertheless, does not violate social interactions.Scales are easily removed when washing and 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 using a high frequency, it is enough to pass pigmented neoplasms twice.This requires no 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 structures are affected in addition to age formation.The use of such techniques in order to remove age foci is extremely undesirable.Here, firstly, we carry out the strongest injury to the skin, and secondly, we warm up the tissues and thereby actively stimulate melanocytes.On the one hand, we can remove pigmenting hyper, and on the other, we actively stimulate melanogenesis.Ablative methods can be used in patients with hyperpigmentation, but only under the cover of drugs blocking melanogenesis.It can be hydrochinon or professional line of funds.
Laser biorevitalization
Gel and the basis of hyaluronic acid is applied to the face.Under the influence of a neodymium laser, hyaluronic acid easily penetrates into the deeper layers of the skin, moisturizing it.Laser exposure stimulates the synthesis of collagen and elastin, which further enhances the anti -aging effect of the procedure.Thus, you can conduct effective moisturizing 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 for removing vascular pathologies of any degree of complexity combines two lasers, two lengths of waves of neodymium and impulse laser on dyes.Two wavelengths in Multiplex mode can be combined in one flash.
Areas of application
Treatment of vascular lesions of the face and body in patients with any photo type of skin:
- Treatment de telangiectasia of the face and lower extremities, varicose veins, hemangiom, rosacea;
- Correction of "wine spots".
Pigmentation elimination, rejuvenation:
- photography;
- Laser care procedure - the “exit” procedure;
- Laser rejuvenation without a rehabilitation period.
Treatment of problematic skin: removal of vascular and pigment spots of acne and post -acne.
The scope of laser rejuvenation
To date, the device is the only and fully certified picosecond laser, the world's first alekship laser, interacting with the patient’s skin through a safe photo mechanical effect.Thanks to the wavelength, fractional optics (fractional optical array), the regime (photo-mechanical effect) achieves the effect comparable to the CO2-grinding without thermal damage to the epidermis, without rehabilitation.
Areas of application:
- rejuvenation;
- removal of tattoos of any color;
- removal of age spots;
- leather alignment;
- Treatment of melasma;
- Treatment of scars is post -acne.
The mechanism of the photo mechanical effect
When a large number of ultra-powerful pulses in the picosecond range, a laser-induced optical effect is activated.Laser-induced optical zones are created in the fabrics.They look like bubbles located within the epidermis.These bubbles create pressure and shock wave towards the dermis.In the dermis, without any thermal damage, the cytokine cascade, a cellular reaction, during which cells begin to transmit a signal that damage occurred.Active stimulation of reparative processes occurs.We get the result that can be achieved with significant heating of tissues, without thermal damage to cells and extracellular structures.
