Plasma technology cosmetology

The use of plasma technology is a relatively new trend in cosmetology and still not quite understood. The first device has created an alternative to laser rejuvenation, but recent studies show that the possibility of using the plasma is much wider.

Plasma: what is it?

Peeling

In order to understand what kinds of advantages provided by the use of plasma technology, let's first understand what is a plasma. Plasma — it is a gas, which, unlike the usual us stable gases, which consists of not only neutral molecules but also contains charged particles — free electrons and positive and negative ions (and in some cases consists only of those charged particles).

The distinction between 2 types of plasma:

  • high temperature. Such a plasma above the Sun, accounted for than the discharge of the zippers and in the course of fusion. The high temperature of the plasma is considered to be the "classic" fourth aggregate state of substances;
  • the low temperature — low ionization (up 1%). Usually it releases gas to electric currents, the acceleration of the electrons which in turn ionize the atoms. It is precisely this type of plasma employed in technology manufacturing and medicine.

Biomedical effects of plasma

Plasma is the source:

  • heat;
  • reactive forms of oxygen, nitrogen and free radicals;
  • different types of radiation (uv to infrared).

The specific impact on the communicating textile-objectives depends on the type of saw plasma, its dose, flow rate, pressure, the effect of time (the options you that can be affected using the change of equipment) and the characteristics of the stocking.

Originally, the medicine is introduced the thermal effects of plasma. So, the rapid flow of the plasma, obtained with the help of effect of inert gases electric current of the big force, is known as the plasma knife, and is used for dissecting and tissue removal. The ability of plasma or fabric (even though already lower intensity) became the basis for his use and cosmetics.

However, I must say that in recent years has increasingly attracted attention in the technology cold plasma at low temperatures (35-40of), which allows to achieve treatment effects without damage to living tissue.

Currently investigating the possibility to use the ability of cold plasma at low temperature to generate free radicals and ultraviolet radiation to human skin disinfection, as well as the handling of wounds. This exposure will allow you to kill resistant micro-organisms (which is especially important for nosocomial infections), without undermining the own skin. Antimicrobial activity in the plasma is demonstrated not only in experimental animals, however, and in the course of randomized controlled studies in humans: the processing of the ras within two minutes out in the cold argon plasma stimulates a significant reduction in the number of both gram-negative and gram-positive bacteria in wounds.

It also appears that the processing of the ras cold plasma at low temperatures will speed up their improvement. Recent work published in the journal Scientific Reports, has shown that such plasma stimulates the proliferation and differentiation of notsüüdid at the expense of activation of β-catenin-signal path and inhibiting E-cadherin, which is responsible for contact inhibition of cell growth. In mice, the wounds, which was to handle the low temperature of the plasma, is already later than the 15 days mentioned in almost complete restoration of the epidermis and muscle tissue and high density of collagen fibers, while at the same time as the wounds healing in a natural way, that these processes would be much slower.

Recent studies have also shown that cold plasma result of a temporary decline in the barrier function of the sarvkihi and strengthens the skin permeability of medicines and cosmetics. It is assumed that this is related to the reorganization of lipid bilayers by the action of plasma and the formation of temporary channels to facilitate the passing of various substances.

Plasma methods, cosmetics

Eyelid

The beginning of the era of plasma technology in cosmetology related to the thermal effects of plasma. So, plasma methods of rejuvenation are based on controlled thermal energy to the damaged tissues, with the aim of launching a renewable process and "updates" in the tissues. This principle is basic and the other methods of hardware-rejuvenation, but if the use of plasma has its own characteristics.

Plasma skin regeneration

Pioneer plasma rejuvenation is a technology plasma skin regeneration (Plasma Skin Regeneration, PSR), which was released in 2006. the year as a plasma gas, many of the use of nitrogen inert gas, which is able to replace oxygen, which is necessary, that the oxidation and burning of the skin surface, and thus reduce the burn risk and scarring.

The effect of high-frequency electrical current of the handle of the device takes place the molecules to be of the nitrogen and forms a plasma, which is delivered to the skin non-contact way in the form of short impulses (such contactless way of processing allows the skin to quickly cool down and eliminates risk of burns details of the device). This means that, in fact, plasma is the "vector" of electrical energy.

If the plasma gets on your skin, his energy is quickly distributed over the entire surface and provides a gradient heating of the skin — first of all, the epidermis, then (depending on energy levels) the derma, the formation of the surface zone of irreversible thermal damage, and a deeper zone of the heat change.

It is important that, in contrast to lasers, plasma does not require the chromophores to the skin, so that the warmed tissues of the flowing evenly, without the "explosive" vaporization in the tissues. A layer of old damaged skin serves as a "biological safety of the salaries" of the underlying cells and remain stationary, until there will be a new and then gradually die. In addition, it allows to carry out skin treatment any phototypes and reduces the risk of side effects in the form of scars, infections, and depigmentation. Even in the case where the high energy impact of deepithelization takes place rapidly and is usually complete within 5-7 days after the procedure.

Processes carried out in the skin layer, longer. Immediately after the processing is celebrated to restore the collagen fibers (in these areas, where the temperature of heating exceeds 60per) and the reaction of the thermal shock, then the gradual division of the damaged structures and the activation of the de neocollagenesis and neoelastogenesis. Processes remodeling the derma will continue for at least 3 months after treatment.

  • Energetic processing provides superficial effect of light exfoliation and offers clarification and to harmonise the skin tone and small wrinkles. The course consists of 3-4 procedures with an interval of between 3 weeks and do not need rehabilitation.
  • The procedure using the high energy used for wrinkles correction, improve elasticity and skin tighten (including the skin of the upper and lower eyelid), reduce scars and stretch marks. They are more uncomfortable and comes with a recovery period of 1-2 weeks.

Partial plasma of the RF-technology

Another option is to use special properties of the plasma to carry out the rejuvenating procedure is partial plasma, RF-technology, the resulting 2010

Special tips for the manipulator (in the form of moving rollers, or a flat stationary accessories) organised a number of needle electrodes (spicules). When approaching the skin surface several micrometers powerful electrical rf discharge, passing the electrodes through a design be a flash of plasma (plasma solutions for high density).

They flash the "punch" of the epidermis and the upper layers of the dermis, which form channels, surrounded by an area of thermal damage. If hereinafter referred to as the spin coordinate (or press a). nozzle) spicules extruded these sites ablation, pointing them to additional mechanical impact.

The depth and dimensions of damage also is determined by the energy and the pulse duration (according to studies of the skin of pigs, wells ablation can range from 50-200 mm in depth, and 80-200 mm in diameter, the zone of coagulation — common yet 100 to 200 µm around). Epithelialization the end of the 3-4 days, the processes of remodeling derma last up to 6 months.

Partial plasma of the RF-treatment is recommended to correct the old changes (wrinkles, saturation, etc.), as well as the way the skin tone and reduce scarring. In addition, the speed of the procedures (an average of 10 min for 5 times in the face) allows the use of home improvement for processing large surfaces of the skin, such as the abdomen.

Plasma vs. lasers

Plasma

What are the characteristics of the plasma skin compared to laser, the alternative to which he originally created?

Unlike lasers, plasma can be used on skin of all phototypes. Hyperpigmentation, which may occur after the procedure, in general, occurs less frequently, if the laser treatment. Also has greatly reduced the risk of infection and scars.

Proven to OVER a2-lasers are formed over a uniform depth and diameter of the damage, while at the same time as the case of using the plasma these measurements may vary. In addition to the lasers is to provide a deeper impact, than the plasma. But just more of the soil to the impact of the plasma processing can be one of the reasons for the lower risk of inflammatory hyperpigmentation.

As far as efficiency, then there is a direct comparison of the factional plasma RF-technology and partial WITH a2-laser to remove the scars of acne. One side of the face of the patient (in total, attended by 33 people III and type IV skin) intact by means of a plasma, another laser, 3 the procedure for each species. The depth of the damage in the first case, the varied and 120-150 mm and the diameter was 150-180 mm. Partial WITH2-laser-formed damage to a depth of 300 to 400 mm and a diameter of 100-120 mm. Zone of thermal damage around the pit ablation is a wider case, if the plasma.

Both methods are essentially and practically equivalent to the reduced expression scar acne — 51,1 ± 14,2 up 22.3 ± 8,6 case, if the plasma (improvement 56,4%) and 48,8 ± 15,1 up to 19.9 ± 7,9 that WITH the2-laser (improvement of 59.2%) on a scale of ESSA. In doing so, in response to the laser effect is 12 people (36,4%) developed post-inflammatory hyperpigmentation, and by the plasma processing complications are not registered.

Thus, the plasma allows to fight skin pigmentation, to align the texture and skin tone, and essentially be equal to the non-ablative lasers. High energy plasma, which in turn helps to fight the more serious defects, such as wrinkles, reduced elasticity and the elasticity of the skin, as well as scars acne and stretch marks, but the depth of impact is limited to the top layers of the derma (in the case of lasers, the depth of the thermal treatment zones may be greater than 1 mm).

And although plasma rejuvenation carries a lower risk of side effects and require recovery less time, the efficiency of ablative laser more high. However, these procedures may be the procedures of choice in patients who have dark any type of skin, because they have greatly reduced the risk of inflammatory hyperpigmentation.

In addition, the use of technology plasma evolve, and now appears in more and more future-oriented devices with new features that allow them to escape the comparative "younger brother" of the lasers, and take a separate niche.

In today's market the plasma technology

The main difference between the serious professional plasma apparatus from the portable devices in the home and filtrikorpuse use there is control over it, deep and well skin damage. This is a very important aspect that allows to get predictable results and reduce the risk of unwanted side effects.

A number of new devices that use the options in the plasma, increases every year. It seems even portable devices, which allow the use of energy-plasma is the salon and at home. However, it should be noted that these are installed in the profiles, the effect of which is not able to modify nor the strength nor the depth, nor the processing time, which causes issues with respect to their effectiveness and safety.

At the same time the developers of the professional apparatus, on the contrary, focus their efforts on more advanced equipment and create more controlled technologies, which allow to obtain the expected and stable results.

Interest in plasma technology is growing — this is confirmed by a large number of devices, which arise in the market in recent years. The Plasma of youth, the extension of ago soft, more impact, than the ablative laser, but it comes with less unwanted phenomena and more and more controlled. An additional advantage is the possibility to use plasma treatment for dark phototypes of skin.

In addition to has appeared in the cosmetology of the device, generating a cold low-temperature plasma, which expands significantly the prospects of the use of plasma technology and allows the expected growth of their popularity in the future.
