Laser procedures aimed at rejuvenating the skin and eliminating the signs of aging are increasing in cosmetology.Due to its high efficiency and safety, relatively simple and short recovery periods, laser therapy gradually replace other methods of controlled damage to the skin, such as, for example, in moderate chemicals and average surface.We bring your attention an overview of devices for laser correction of age and photoaging manifestations.
What is the aging
Biological aging is a gradual process of infringement and loss of important functions of the body or part, in particular, the ability to reproduce and regeneration.At the skin level, aging is characterized by the accumulation of genetic defects in the cell, which violates the process of division and differentiation. This genetic disorder is the reason:
- depletion of dermal epidermis;
- violation of skin barrier function;
- Increases transpidermal moisture loss with dry skin development.
The consequences of internal disorders are the formation of external manifestations of aging - ptosis, wrinkles and skin folds.The process of aging is irreversible, but cosmetology has a way of prevention of age -related changes.Premature aging is mainly photo starting.Under the influence of ultraviolet radiation, it occurs:
- violation of cell differentiation process;
- uneven distribution of melanocytes;
- thickening of the stratum corneum (hyperkeratosis);
- Microfing and skin color.
It also violates irrational nutritional conditions, insufficient water use, bad habits and poor environmental factors.
Basic Morphological Type of Aging
Based on the external signs related to related skin changes, 5 main types of aging are distinguished:
- Fine wrinkles. Its main manifestation: a clear vascular pattern, a large number of small wrinkles throughout the face, which is obvious in static, without muscle participation.
- Muscle type. It is a feature of the Central Asian population, where the facial muscles are well developed, and the subcutaneous fat tissue is thin.This type is characterized by the appearance of nasolabial folds, smoothness and weakness of the face.The wrinkles look like large skin breaks.They are deep, which is clearly seen in static.
- Style according to the type of ptosis of gravity. Features for oily skin owners with a large number of sebum glands.Oval changes are due to the fact that the fat bag in the face is transferred after the skin.Bryli, second chin, large folds appear.
- City with a tired type of face. It is expressed by the decrease in the elasticity of soft tissue, pasta, swelling.Nezoglyny folds are clearly visible, the corner of the mouth goes down.
- Mixed type.The combination of gravity ptosis, tired face and small wrinkles.It happens more often than all other types.
Methods of combating skin aging in modern cosmetology
All methods used to eliminate skin aesthetic imperfections can be divided into three main groups: hardware, injection and care procedures.The aesthetic method that improves the condition of the epidermis suggests:
- the use of professional cosmetics;
- Handles surface chemical skin and care procedures.
Injection cosmetology includes five main instructions:
- Stimulation of collagen and elastin synthesis;
- Biorevitalization;
- Bio repair;
- volumetric correction of hyaluronic acid -based filler;
- Working with muscle frames - Botulinum Toxin Justo.
Hardware cosmetology:
- Laser rejuvenation;
- Other hardware effects: lift radio frequency, microscope, broadband light, ultrasound, myostimulation, etc.
Approach to rejuvenation
The process of eliminating age -related changes is multicomponent.Rejuvenation is not just the launch of de neocollagenesis.Removing spots -Age spots or seborrheic keratosis are rejuvenation.Issue the vascular mesh also specified in rejuvenation.For example, angiogenesis is increasing 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.
Laser rejuvenation methods
Ablation method:
- Laser fraction-CO2;
- Not a fraction-co2 laser;
- Erby laser.
Non -dimensional techniques:
- neodymowe rejuvenation;
- not ablation;
- Alexandrite rejuvenation is cool.
Ablation techniques suggest damage to the skin.These include:
- Classical techniques. This is a laser grinder with 100%full overlap.They are usually performed at the epidermis level, no more deeper than the basal membrane.
- Fractions. Continuous laser radiation is divided into fractions with overlap from 5 to 70%.It penetrates the deeper layers of the skin, into the dermis.
Laser action mechanism for rejuvenation
The effect of stimulating laser radiation on the fabric is based on the activation of fibroblasts, de neocollagenesis.Laser energy, damaging or without damaging the epidermis, trying to reach the dermal layer, more often with heating, creating controlled trauma where all regenerative processes are launched, fibroblasts begin to synthesize fiber.
Rejuvenation by laser CO2
CO2 rejuvenation is carried out as a violation of skin integrity.It involves prolonged recovery.Erbium laser has no rejuvenation effect.
Hints:
- Aging of gravity ptosis;
- Post -acne scars, other scars;
- small wrinkles;
- Expressing elastosis.
Neodymowe rejuvenation
Neodymium lasers are characterized by non -road effects.The 1064 Nm wavelength allows radiation to enter the skin of the skin to the dermis level and there, due to heating, to stimulate the synthetic process, fibroblast work.The epidermis is not damaged.The recovery period is not required.No laser procedure can be done without recovery, another thing is that the level of neodymium radiation violation is minimal: redness lasts 3-6 hours.
Hints:
- type of aging with small wrinkles;
- small static wrinkles;
- expanded pores;
- Uneven skin.
Alexandrite rejuvenation is cool
It is carried out on laser rejuvenation tools.Radiation with a wavelength of 755 nm is mostly absorbed by melanin.This makes cold lasers very much needed to eliminate pigmentation and improve skin color.The difference in cold rejuvenation and other methods is that the photo is used primarily here, and not a thermal effect.That is, neokollagenesis and increased fibroblast function are launched without heating, without heat damage to the dermis and epidermis.
Hints:
- pigmentation;
- expanded pores;
- post -acne;
- small wrinkles;
- General reduction in skin tone.
Combined system.The device comes with a neodymium laser with a wavelength of 1064 nm and a cold laser with a wavelength of 755 nm.
Application field:
- removal of spots -age of various etiology and complexity;
- Unresolved rejuvenation with a comprehensive solution to photo problems begins at one session without a period of recovery;
- Hair Total Hair Removal of any color, any structure, in all pictures of skin type;
- Removes any vascular pathology, where the body parts with vessels are up to 4 mm.
This device lets you set the optimal settings for the radiation parameters and the frequency of the pulse repeats.Solve five problems for one procedure:
- hair removal and removal to cold lasers;
- Remove for tanning or very bright hair, removal of vessels in the face and lower legs, acne treatment, rejuvenation, laser biorevitalization on neodymium laser.
The removal of pigments
Only lasers can destroy pigments anywhere, even when they are mature.Peels and creams act more superficely.Excellent results can be found in the lower eyelids ("dark circles"), neckline, back, face and hands.The place immediately after the first procedure became dark, and then gradually left.On the surface for a week, many pebbles can be observed, which, however, does not violate social interactions.The scale is easily removed when washing and is almost invisible after using a moisturizer.To get rid of pigmentation forever, only 2-4 procedures with intervals a month are enough.
This procedure is carried out at a high speed, that is, when using high frequency, it is sufficient to pass the pigmented neoplasms twice.This takes no more than 10-15 minutes, even though we are talking about the pigmentation of hyper all over the face.Cold radiation is absorbed by melanin 50 times more active than hemoglobin, so no other structure is affected in addition to age formation.The use of such techniques to eliminate age focus is very unwanted.Here, first, we have a strong injury to the skin, and second, we heat the tissue and thus actively stimulate melanocytes.On the one hand, we can get rid of the hyper, and on the other hand, we actively stimulate melanogenesis.Ablative methods can be used in patients with hyperpigmentation, but only under the cover of drugs that prevent melanogenesis.It can be hydrocinon or professional fund line.
Laser's biorevitalization
Gel and hyaluronic acid base are applied to the face.Under the influence of neodymium lasers, hyaluronic acid easily penetrates the deeper layers of the skin, moisturizing it.Laser exposure stimulates collagen and elastin synthesis, which in turn enhances the anti -aging effect of the procedure.Therefore, you can perform an effective moisturizer of the neck, neckline, hand an hour before important events in life.There is no unpleasant sensation.The duration of the procedure is 15 minutes.Without seasonal restrictions.
Laser rejuvenation on the device
Innovative laser systems to eliminate vascular pathology from any of the complexities combine two lasers, two neodymium wavelengths and laser impulses on dyes.Two wavelengths in multiplex mode can be combined in one lightning.
Application field
Treatment of face and body vascular lesions in patients with skin photo type:
- Treatment of de telangiectasia face and lower leg, varicose veins, hemangiome, rosacea;
- "Wine spots" correction.
Elimination of pigmentation, rejuvenation:
- Photography;
- Laser care procedure - "out" procedure;
- Laser rejuvenation without a period of recovery.
Troubleshooted skin treatment: removal of spots -vascular spots and acne pigments and post -acne.
Scope of laser rejuvenation
To date, this device is the only certified Picosecond laser, the world's first Laser Alekship laser, interacting with the patient's skin through a safe photo effect.Thanks to wavelengths, fractional optics (fractional optic array), regime (mechanical effects) achieves effects comparable to CO2 grinders without thermal damage to the epidermis, without recovery.
Application field:
- rejuvenation;
- removal of any color tattoo;
- removal of spots -age spots;
- skin alignment;
- Melasma treatment;
- Scarring treatment is post -acne.
Mechanism of mechanical effects of photos
When a large number of ultra pulses are powerful in the picosecond range, the laser -caused optic effect is activated.The optical zone caused by the laser is created in the fabric.They look like bubbles located in the epidermis.These bubbles produce pressure and shock waves towards the dermis.Inside the dermis, without any thermal damage, cytokine circuits, cellular reactions, where cells begin to send signals that damage occurs.The active stimulation of the reparative process takes place.We get the results that can be achieved with significant tissue heating, without thermal damage to cells and extracellular structures.
