The laser procedures aimed at rejuvenating the skin and eliminating the 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 moves other methods of damage controlled to the skin, such as, for example, in medium and superficial chemical skins.We bring to your attention an overview of the devices for the laser correction of age and photojugal events.
What is getting older
A aging in biology is a process of gradual violation and loss of important body functions or parts, in particular, the ability to reproduce and regeneration.In terms of skin, aging is manifested by the accumulation of genetic defects in cells, which violate the division and differentiation process. These genetic disorders become reason:
- Thinning of the dermal-epidermal joint;
- Violations of the leather barrier function;
- Increase the loss of transsepidermal humidity with the development of dry skin.
The consequence of internal disorders is the formation of external aging manifestations: ptosis, wrinkles and folds of the skin.The aging process is irreversible, but cosmetology has means of preventing age -related changes.Premature aging is mainly starting from photos.Under the influence of ultraviolet radiation, it occurs:
- violation of the cell differentiation process;
- irregular distribution of melanocytes;
- thickening of the corneous layer (hyperkeratosis);
- Microfing and skin color.
It also violates the state of the irrational nutrition of the body, an insufficient water consumption, bad habits and adverse environmental factors.
Types of basic morphological aging
Based on the prevalent external signs of age -related leather changes, 5 main types of aging are distinguished:
- Finely wrinkled type. Its main events: a pronounced vascular model, a large number of small wrinkles throughout the face, which occur in static, 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 fat fabric is thin.This type is characterized by the appearance of the nasolabial folds, by the softness and blur of the oval of the face.Wrinkles look like a large breaking of the skin.They are deep, which are clearly visible in static.
- Style by type of gravitational ptosis. Characteristic for oily leather owners with a large number of sebaceous glands.The oval changes due to the fact that the face fat bags are moved after the skin.Brili, the second chin, appear large folds.
- City by type of tired face. It is expressed by a decrease in the elasticity of soft tissues, pastes, swelling.Nezoglyny's folds are clearly visible, the corners of the mouth are down.
- Mixed type.A combination of gravitational ptosis, tired face and small wrinkles.It occurs more often than all other types.
Methods to combat skin aging in modern cosmetology
All the methods used to eliminate the 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;
- Conduct surface chemical peels and care procedures.
The injection cosmetology includes five main directions:
- stimulation of injection of collagen and elastin synthesis;
- biorevitalization;
- Bio repair;
- Volumetric correction of the filler based on hyaluronic acid;
- Work with the muscle frame - Justo botulinum toxin.
Hardware cosmetology:
- laser rejuvenation;
- Other hardware effects: radio frequency lifting, microcurrentant, broadband light, ultrasound, myostruration, etc.
Approaches to rejuvenation
The process of eliminating age -related variations is multicomoting.Rejuvenation is not only the launch of De Neocollagenesi.The removal of age points or seborrheic keratosis is rejuvenation.The removal of a pronounced vascular network is also a rejuvenation.For example, Angiogenesis intensifies with age.There are multiple pathological vases, they become more evident.By removing these ships, we improve the condition and appearance of the face, which visually makes the younger and more attractive face.
Basic laser rejuvenation methods
Ablation methods:
- fractional laser-co2;
- Non-fractional-co2 laser;
- Erby Laser.
Non -dimensional techniques:
- Noodymowe rejuvenation;
- not ablation;
- Alexandrite cold rejuvenation.
The ablation techniques suggest damage to the skin.These include:
- Classic techniques. These are laser grid with a 100%complete overlap.They are usually performed at the level of epidermis, no deeper than the basal membrane.
- Fractional. The continuous laser radiation is divided into fractions with an overlap from 5 to 70%.Penetrates in deeper layers of the skin, in the dermis.
The mechanism of action of laser for rejuvenation
The stimulating effect of laser radiation on the tissue is based on the activation of fibroblasts, de neocollagenesis.The energy of the laser, harmful or without damaging the epidermis, tries to reach the dermal layers, more often through heating, create 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 the integrity of the skin.Implies prolonged rehabilitation.The Erbio laser does not have this effect of rejuvenation.
Indications:
- Type of aging of gravitational ptosis;
- scars of the post -acne, other scars;
- small wrinkles;
- Expressed elastosis.
Noodymowe rejuvenation
Neodimium laser is characterized by non -abroad effects.The 1064 Nm wavelength allows radiation to move on to deep layers of the skin to the level of the dermis and there, due to heating, to stimulate synthetic processes, the work of the 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 radiation of neodymium is minimal: the redness lasts 3-6 hours.
Indications:
- Type of aging with small wrinkles;
- small static wrinkles;
- expanded pores;
- Irregular complexion.
Alexandrite cold rejuvenation
It is carried out on a laser rejuvenation system.Radiations with a 755 Nm wavelength are mainly absorbed by melanin.This makes an indispensable cold laser to eliminate pigmentation and improve the color of the skin.The differences in cold rejuvenation and in other methods are that the photo is used mainly here and not the photo of the thermal effect.That is, the neocollagenesis and the increase in the function of the fibroblasts are launched 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 neodimium laser with a wavelength of 1064 Nm and a cold laser with a wavelength of 755 Nm.
Application areas:
- removal of age spots of various etiologies and complexity;
- Non -skilled rejuvenation with a complete solution to the problems of the photo that start in a session without a rehabilitation period;
- Total hair transport of any color, any structure, in all photos of the skin types;
- Removal of any vascular pathologies, on any part of the body with a diameter of the pot up to 4 mm.
The device allows you to set optimal settings for radiation parameters and the frequency of repeated impulses.Solve five problems for a procedure:
- hair removal and removal on a cold laser;
- Remove for tanning or very bright hair, removal of vases on the face and lower limbs, treatment of acne, rejuvenation, laser biorevitization on neodimium laser.
Pigment removal
Only a laser can destroy the pigment at any mature age.The skins and creams act more superficially.Excellent results can be obtained in the lower eyelids ("dark circles"), neckline, back, face and hands.The point immediately after the procedure is obscured before, then leaves gradually.On the surface during a week of the week, abundant peeling can be observed, which, however, does not violate social interactions.The stairs are easily removed during washing 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 pass the pigmented neoplasms twice.This requires no more than 10-15 minutes, even if we are talking about hyper pigmentation of the entire face.Cold radiations are absorbed by Melanin 50 times more actively than hemoglobin, therefore no other structures are interested in addition to the formation of age.The use of these techniques in order to remove age outbreaks is extremely undesirable.Here, firstly, we perform the strongest injury to the skin and, secondly, we heat the tissues and then actively stimulate the melanocytes.On the one hand, we can remove 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 drugs that block melanogenesis.It can be hydrochinone or line of professional funds.
Laser biorevitization
The gel and the base of hyaluronic acid are applied to the face.Under the influence of a neodimium laser, hyaluronic acid easily penetrates the deepest layers of the skin, hydrating it.Laser exposure stimulates the synthesis of collagen and elastin, which further improves the anti -aging effect of the procedure.Therefore, you can conduct effective hydration of the neck, neckline, hands one 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 the removal of vascular diseases of any degree of complexity combines two laser, two lengths of waves of neodymium and laser with impulses on the dyes.Two wavelengths in multiplex mode can be combined in a flash.
Application areas
Treatment of vascular lesions of the face and body in patients with any type of skin:
- Treatment of telangectasia of the face and the lower limbs, varicose veins, emangioma, rosacea;
- Correction of "points of wine".
Elimination of pigmentation, rejuvenation:
- photograph;
- Laser assistance procedure - the "exit" procedure;
- Laser rejuvenation without a rehabilitation period.
Treatment of problematic skin: removal of vascular spots and pigments of acne and post -acne.
The scope of laser rejuvenation
To date, the device is the only completely certified picosecond laser, the first Alekship laser in the world, interacting with the patient's skin through a safe photographic mechanical effect.Thanks to the wavelength, the fractional perspective (fractional optical array), the regime (photo-mechanical effect) reaches the effect comparable to the culture of CO2 without thermal damage to the epidermis, without rehabilitation.
Application areas:
- rejuvenation;
- removal of any color tattoos;
- removal of age points;
- leather alignment;
- Melasma treatment;
- The treatment of scars is post -acne.
The mechanism of the photographic mechanical effect
When a large number of ultra powerful impulses are activated in the range of picoseconds, an optical effect induced by the laser is activated.The optical areas induced by the laser are created in the fabrics.They seem 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 occurred damage.A active stimulation of reparative processes occurs.Opinion the result that can be obtained with significant heating of tissues, without thermal damage to cells and extracellular structures.
