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 skin damage, such as medium and medium chemical peels.We bring to your attention an overview of laser correction devices of age and photoist.
What is aging
Aging in biology is a process of gradual disorder and loss of important functions of the body or its parts, more special the ability to reproduce and regeneration.At skin level, aging is manifested by the accumulation of genetic defects in cells that disrupt the process of separation and differentiation. These genetic disorders become the cause:
- thinning of the dermal epidermal joint;
- disorders of the barrier function of the skin;
- Increase the loss of transpidermal moisture with the development of dry skin.
The consequence of internal disorders is the formation of external manifestations of aging - ptosis, wrinkles and folds of the skin.The aging process is irreversible, but cosmetology has the means to prevent age -related changes.Premature aging is mostly starting photos.Under the influence of ultraviolet radiation occurs:
- violation of the cell differentiation process;
- uneven distribution of melanocytes;
- thickening of the horn layer (hyperkeratosis);
- Microfing and skin color.
It also disrupts the condition of irrational body nutrition, insufficient use of water, bad habits and adverse environmental factors.
Basic morphological types of aging
Based on the prevailing external signs of age changes in the skin, 5 main types of aging are distinguished:
- Fine wrinkled type. Its main manifestations: a pronounced vascular model, a large number of small wrinkles on the face that manifest themselves in the static without the involvement of the muscles.
- Muscle type. It is characteristic of the inhabitants of Central Asia, in which the muscles of the face are well developed, and a layer of subcutaneous fat is thin.This type is characterized by the appearance of nasolabial folds, the smoothness and blurry of the oval of the face.Wrinkles look like a big breakdown of the skin.They are deep, which are clearly visible in the static.
- Style by type of gravitational ptosis. Characteristic of owners of oily skin with a large number of fatty glands.The oval changes due to the fact that the fat bags of the face are shifted after the skin.Brilli, the second chin, big folds appear.
- A city by type of tired face. It is expressed by reducing the elasticity of soft tissues, pastes, swelling.Nenogly the folds are clearly visible, the corners of the mouth descend down.
- Mixed type.A combination of gravitational ptosis, tired face and small wrinkles.It is more common than all other species.
Methods for combating skin aging in modern cosmetology
All methods used to eliminate aesthetic skin imperfections can be divided into three main groups: hardware, injection and care procedures.Aesthetic methods that improve the condition of the epidermis suggest:
- use of professional cosmetics;
- Conducting superficial chemical peels and care procedures.
Injection cosmetology includes five main directions:
- injectable stimulation of collagen and elastin synthesis;
- Biorevitalization;
- Organic 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, microcounts, broadband light, ultrasound, myostimulation, etc.
Rejuvenation approaches
The process of eliminating age -related changes is multicomponent.Rejuvenation is not only the launch of neocolganesis.Removal of age spots or seborrheic keratosis is rejuvenation.Removing a pronounced vascular network is also rejuvenation.For example, angiogenesis increases with age.There are more pathological vessels, they become more noticeable.By eliminating these vessels, we improve the condition and appearance of the person, which visually makes the person more jelly and more attractive.
Basic Laser Rejuvenation Methods
Ablation methods:
- Fractional-CO2 laser;
- not fractional-CO2 laser;
- Erby Laser.
Unsuned techniques:
- Neodymowe rejuvenation;
- not ablation;
- Cold rejuvenation of Alexandrite.
Ablation techniques suggest skin damage.These include:
- Classic techniques. These are laser grinding machines with a full 100%overlap.They are usually performed 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%.It penetrates in deeper layers of the skin, into the dermis.
The mechanism of action of rejuvenation lasers
The stimulating effect of laser radiation on the tissue is based on the activation of fibroblasts, depocolocoles.The energy of the laser, damaging or without damaging the epidermis, tries to reach the dermal layers, more often by heating, creates such a controlled trauma, in which all regenerative processes are started, the fibroblasts begin to synthesize the fibers.
Rejuvenation from laser CO2
CO2 rejuvenation is done in violation of skin integrity.It includes prolonged rehabilitation.The erbial laser has no such rejuvenation effect.
Indications:
- Type of gravity ptosis;
- Scars from post -app, other scars;
- small wrinkles;
- Expressed elastosis.
Neodymium rejuvenation
The Neodymium laser is characterized by non -abusive effects.The wavelength of 1064 Nm allows radiation to pass into deep layers of the skin to the level of the dermis and there, due to heating, to stimulate the synthetic processes, the work of the fibroblasts.The epidermis is not damaged.The recovery period is not required.No laser procedure can do without rehabilitation, another thing is that the degree of disorders of the radiation of the neodymium is minimal: the redness lasts 3-6 hours.
Indications:
- type of aging with small wrinkles;
- Small static wrinkles;
- Extended pores;
- Uneven complexion.
Cold rejuvenation of Alexandrite
It is performed on a laser rejuvenation apparatus.Radiation with a wavelength of 755 nm is absorbed mainly 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 used mainly here, not the photo of the thermal effect.That is, neoochenesis and the increase in the function of fibroblasts are fired without heating, without thermal damage to the dermis and epidermis.
Indications:
- pigmentation;
- Extended pores;
- Post -acne;
- small wrinkles;
- General reduction 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.
Application areas:
- Removal of age spots from different etiologies and complexity;
- Incapable of rejuvenation with a complete solution to the problems of the photo starting in a session without a rehabilitation period;
- General hair removal of any color, every structure, in all skin types;
- Removal of any vascular pathologies in each part of the body with a diameter of up to 4 mm.
The device allows you to set optimal settings for radiation parameters and the frequency of recurrent pulses.Solving five problems for one procedure:
- hair removal and removing a cold laser;
- Remove for complexion or very bright hair, removal of vessels of the face and lower limbs, treatment of acne, rejuvenation, laser biorevitalization of the Neodymium laser.
Removal of pigment
Only a laser can destroy the pigment at any age, even adulthood.Cars and creams work more than a matter of mind.Excellent results can be obtained in the lower eyelids ("dark circles"), neckline, back, face and hands.The place immediately after the procedure first darkens and then gradually leaves.On the surface of it, there can be abundant peeling, which nevertheless does not disrupt social interactions.Scales are easily removed when washed and almost invisible after applying a moisturizer.To get rid of pigmentation forever, only 2-4 procedures are sufficient with an interval per month.
The procedure is performed at a sufficiently high speed, that is, when using a high frequency, it is sufficient to transfer pigmented neoplasms twice.This requires no more than 10-15 minutes, even if we are talking about the hyper pigmentation of the whole face.Cold radiation is absorbed by melanin 50 times more active than hemoglobin, so that other structures are not affected in addition to age formation.The use of such techniques to eliminate age outbreaks is extremely undesirable.Here, first, we perform the most severe skin injury and secondly, we score the tissues and thus actively stimulate melanocytes.On the one hand, we can remove the pigmented hyper, and on the other, we actively stimulate melanogenesis.Ablative methods can be used in patients with hyperpigmentation, but only under the guise of drugs that block melanogenesis.This can be a hydroquinone or a professional line of remedies.
Biorevitalization
The gel and the base of hyaluronic acid is applied to the face.Under the influence of a neodymium laser, hyaluronic acid easily penetrates the deeper layers of the skin, moisturizing it.Laser exposure stimulates the synthesis of collagen and elastin, which further enhances the effect of combating the procedure.This way, you can perform effective neck moisturizing, 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 of the device
An innovative laser system for the removal of vascular pathologies of any degree of complexity combines two lasers, two lengths of waves of neodymium and pulse laser on the dyes.Two wavelengths in multiplex mode can be combined with one flash.
Areas of application
Treatment of vascular lesions of the face and body in patients with any type of skin photo:
- Treatment de telangiectasia of the face and lower limbs, varicose veins, hemangioma, rosacea;
- Correction of "wine spots".
Elimination of pigmentation, rejuvenation:
- photography;
- Laser care procedure - output procedure;
- Laser rejuvenation without a period of rehabilitation.
Treatment of problem skin: Removal of vascular and pigment spots from acne and after -Ane.
The scope of laser rejuvenation
To date, the device is the only and fully certified picosecond laser, the world's first laser of allegation laser interacting with the patient's skin through a safe photo mechanical effect.Due to the wavelength, fractional optics (fractional optical array), the regimen (photomechanical effect) achieves the effect comparable to the grinding of CO2 without thermal damage to the epidermis without rehabilitation.
Application areas:
- rejuvenation;
- removal of tattoos of any color;
- Removal of age spots;
- Skin alignment;
- Treatment of melasma;
- The treatment of scars is after -ACN.
The mechanism of photo mechanical effect
When a large number of over-power impulses in the pikosecond range, a laser-induced optical effect is activated.Laser optical areas 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 thermal damage, the cytokine cascade, the cell reaction, during which the cells begin to transmit a signal that occurs damage.Active stimulation of reparative processes occurs.We get the result that can be achieved with significant tissue heating without thermal damage to cells and extracellular structures.
