Laser methods that aim to rejuvenate the skin and to eliminate signs of aging are increasingly widespread in cosmetology.Due to its high efficiency and security, a relatively simple and short recovery phase gradually displaces laser therapy other methods of controlled damage to the skin, e.g.B. for example in the middle and superficial chemical shell.We give you an overview of devices for the las correction of the manifestations of old and photography.
What is aging
Age 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 manifests itself through the accumulation of genetic defects in cells that violate the process of division and differentiation. These genetic disorders become the reason:
- Thinning of the dermalepidermal joint;
- Violations of the barrier function of the skin;
- Increase the Transpidal 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 folds.The aging process is irreversible, but cosmetology has funds to prevent age changes.Against early aging is primarily a photo.Under the influence of the ultraviolet radiation, it occurs:
- Violation of the process of cell differentiation;
- Unequal distribution of melanocytes;
- Thickening of the stratum corneum (hyperkeratosis);
- Microfing and skin color.
It also violates the state of irrational nutrition, inadequate water consumption, bad habits and negative environmental factors.
Basic morphological types of aging
Based on the prevailing external signs of age -related skin changes, 5 main types of aging are differentiated:
- Finely crumpled guy. Its main manifestations: a pronounced vascular pattern, a large number of small folds in the entire face, which manifest themselves in statics, without muscle participation.
- Musical type. It is characteristic of residents of Central Asia in which the facial muscles are well developed, and a layer of subcutaneous adipose tissue is thin.This type is characterized by the appearance of nasolabial wrinkles, the smoothness and blurring of the oval of the face.Folds look like large breaks.They are deep that are clearly visible in statics.
- Style according to the type of gravitational turkey. Characteristic of owners of oily skin with a large number of sebum glands.The oval changes due to the fact that fat bags of the face are moved down to the skin.Bryli, the second chin, appear large wrinkles.
- City to tired face. It is expressed by a decrease in the elasticity of soft tissues, pastes and swelling.Nezogllyy folds are clearly visible, the mouth angles are bended.
- Mixed type.A combination of gravitational pens, tired face and small folds.It occurs more often than all other types.
Methods to combat skin aging in modern cosmetology
All methods used to remove aesthetic defects in the skin can be divided into three main groups: hardware, injectable and care process.Aesthetic methods that improve the condition of the epidermis suggest:
- Use of professional cosmetics;
- Implementation of surface chemical shells and care processes.
The injection cosmetology comprises five main instructions:
- Injection stimulation of collagen and elastin synthesis;
- Biorevitalization;
- Bio -injury;
- Volumetric correction of hyaluronic acid -based filler;
- Working with muscle frames - botulinum toxin Justo.
Hardware cosmetology:
- Laser rejuvenation;
- Other hardware effects: radio frequency lifts, micro running, broadband light, ultrasound, myostimulation, etc.
Approaches to rejuvenation
The process of eliminating age -related changes is a multi -component.The rejuvenation is not just the introduction of de neocollaagenesis.Removing age spots or seborrheic keratosis is a rejuvenation.Removing a pronounced vascular network is also a rejuvenation.For example, angiogenesis increases with age.There are more pathological vessels, they become clearer.When we remove these vessels, we improve the condition and appearance of the face, which makes the face visually 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;
- no ablation;
- Cold Alexandrite rejuvenation.
Ablation techniques indicate damage to the skin.This includes:
- Classic techniques. These are laser grinders with a complete overlap of 100%.They are usually carried out on the epidermis level, not lower than the basal membrane.
- Fractional. The continuous laser radiation is divided into indications with an overlap from 5 to 70%.It penetrates into the dermis in deeper layers of skin.
The mechanism of action of lasers to rejuvenate
The stimulating effect of the laser radiation on the fabric is based on the activation of fibroblasts de neocollaagenese.The energy of the laser, which damage the epidermis or damage without damage, tries to achieve the skin layers more often by heating, a controlled trauma in which all regenerative processes are launched, and fibroblasts begin to synthesize the fibers.
Rejuvenation by laser CO2
CO2 rejuvenation is carried out under violation of the integrity of the skin.It includes longer rehabilitation.The Erbium laser has no such impact on rejuvenation.
Indications:
- aging type of gravitational turkey;
- Scars of the post office acne, other scars;
- small folds;
- Expressed elastosis.
Neodymowe rejuvenation
The neodymium laser is characterized by effects without a section.The wavelength of 1064 Nm enables radiation to stimulate the work of fibroblasts in deep layers of the skin up to the level of the dermis and because of heating to stimulate synthetic processes.The epidermis is not damaged.The recovery phase is not necessary.A single laser process can do without rehabilitation.Another thing is that the degree of violations of neodymium radiation is minimal: reddening takes 3-6 hours.
Indications:
- Type of aging with small folds;
- small static folds;
- Extended pores;
- Uneven complexion.
Cold Alexandrite rejuvenation
It is carried out on a laser rejuvenation.The radiation with a wavelength of 755 Nm is mostly absorbed by Melanin.This makes a cold laser indispensable to eliminate pigmentation and improve the 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.This means that neocollage and the increase in the function of fibroblasts are started without heating without thermal damage to the dermis and epidermis.
Indications:
- Pigmentation;
- Extended pores;
- Post -Acne;
- small folds;
- General decrease in skin tone.
Combined system.The device is equipped with a neodyme laser with a wavelength of 1064 Nm and a cold laser with a wavelength of 755 Nm.
Areas of application:
- Distance from age spots of different etiologies and complexity;
- Non -appy rejuvenation with a comprehensive solution for the problems of the photo that begin in a session without rehabilitation phase;
- Total hair hair removal of every color, every structure, on all photos of skin types;
- Removing vascular pathologies on each body part with a vascular diameter of up to 4 mm.
With the device you can define optimal settings for radiation parameters and the frequency of repeating impulses.Solve five problems for a procedure:
- Hair removal and distance on a cold laser;
- Remove for browning or very light hair, the removal of vessels on the face and the lower extremities, the treatment of acne, rejuvenation, laser biorevitalization on the neodyme laser.
Pigment removal
Only a laser can destroy the pigment in any, even mature age.Shells and creams look superficial.Excellent results can be achieved in the lower eyelids ("dark circles"), in the back, face and in the hands.The point immediately after the procedure darkens for the first time and then gradually leaves.A lot of peeling can be observed on the surface during a week, which nevertheless does not violate social interactions.The scales can be slightly removed when washing and almost invisible after applying a moisture cream.In order to get rid of pigmentation forever, only 2-4 procedures with one interval per month are sufficient.
The procedure is carried out at a sufficiently high speed, i.e. when using a high frequency, it is sufficient to pass pigmented neoplasms twice.This does not require more than 10-15 minutes, even if we talk about the hyperpigmentation of the entire face.Cold radiation is absorbed by Melanin 50 -more actively than hemoglobin, so that no other structures are affected in addition to age education.The use of such techniques to remove the retirement varieties is extremely undesirable.First of all, we carry out the most severe violation of the skin, and secondly, we warm up the tissue and thus actively stimulate melanocytes.On the one hand, we can remove pigmentation hyper and actively stimulate melanogenesis on the other.Ablative methods can be used in patients with hyperpigmentation, but only under the cover of medicines that block melanogenesis.It can be hydrochinone or professional terrain of funds.
Laser bioretization
Gel and the basis of the hyaluronic acid is applied to the face.Under the influence of a neodymic laser, hyaluronic acid penetrates slightly into the deeper layers of the skin and moistened them.The laser exposure stimulates the synthesis of collagen and elastin, which further improves the anti -aging effect of the procedure.Therefore, one hour before an important event in life you can carry out effective moisture moisture and hands.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 complexity level combines two lasers, two lengths of waves of neodymium and pulse laser on dyes.Two wavelengths in multiplex mode can be combined with a flash.
Areas of application
Treatment of vascular lesions of the face and body in patients with a photo type of skin:
- Treatment of the telangiektasia of the face and lower extremities, varicose veins, hemangioma, rosacea;
- Correction of "wine stains".
Pigmentation excretion, rejuvenation:
- Photography;
- Laser care process - the procedure "end";
- Laser rejuvenation without rehabilitation phase.
Treatment of problematic skin: removal of vascular and pigment spots from acne and post -acne.
The scope of the laser rejuvenation
So far, the device has been the only and fully certified picosecond laser, the world's first Alekship laser, which interacts with the patient's skin through a safe photographic effect.Thanks to the wavelength, the regime (photo-mechanical effect) reaches the effect that is comparable to the CO2 grinding without thermal damage to the epidermis, comparable without rehabilitation, without thermal damage to the epidermis.
Areas of application:
- Rejuvenation;
- Distance from tattoos of all color;
- Distance from age spots;
- Leather alignment;
- Treatment of Melasma;
- The treatment of scars is post -acne.
The mechanism of the photo mechanical effect
If a large number of ultra-powerful impulses in the picosecond area are activated by a laser-induced optical effect.Laser -induced optical zones are created in the fabrics.You look like blowing inside the epidermis.These bubbles generate pressure and shock wave in the direction of the dermis.In the dermis without thermal damage, the cytokine mascade, a cellular reaction in which cells transmit a signal that has occurred.Active stimulation of reparative processes occurs.We get the result that can be achieved with a significant warming of tissues without thermal damage to cells and extracellular structures.
