Before it talks about fractional laser rejuvenation, it is worth touching the topic of aging skin and understanding the processes it contains.
Skin agency processes and their causes
The condition and appearance of the skin are determined by the extension rate of their cells and fibers of the connective tissue as well as the moisture level of all layers.Fibroblasts are responsible for the synthesis of collagen and elastin in the dermis.And the continuous renewal of the epidermis is ensured by the presence of stem cells that are actively shared.
Cytokines - biologically active molecules that regulate cell activity and force them to match, have stimulating effects on the tissue.Cytokines determine the survival of cells, their division, growth and functional activity.These molecules are quickly transmitted from one cage to the other, which leads to a "cascade" of changes.
Age -related changes are due to the general slowdown of blood circulation and metabolism in the tissues, a decrease in cell division, their synthetic activity.For example, the collagen content in the dermis from the age of 25 decreases with an average speed of 1% per year.The quality of the collagen is also reduced.It becomes relaxed and cannot deliver the previous skin tone.The concentration of hyaluronic acid is reduced, on the amount of which the skin's moisture level depends, the activity of fibroblasts and other cells depends.
An additional aging factor is the ultraviolet radiation, under which the fibers of elastin and collagen are destroyed, which ensures the elasticity of the skin, the expansion of surface vessels with the formation of vascular stars and networks.The protective reaction of the skin in the form of the production of an additional amount of melanin, an increase in the number of layers of epidermal cells, causes the appearance of age spots, a heterogeneous complexion.
The result of all these internal processes are external manifestations of aging:
- Loss of the elasticity and elasticity of the skin, prolapse of the soft tissue of the face with the formation of nasolabial folds, "flew" in the area of cheeks, fuzzy face contour;
- dynamic and static wrinkles;
- Uneven skin color with hyperpigmentation focus;
- The occurrence of tulangiektasia;
- Reduction of the moisture level of tissues.
To rejuvenate the skin, we have to eliminate all the above -mentioned external changes.So that the result of anti -aging effects is long, it is also necessary to restore the normal level of metabolic processes.
The process of fractional laser rejuvenation of the face enables you to solve both problems as follows:
- Tissue affected by age -related changes are removed using a controlled damage effect that enables stem cells.
- The intensity of the harmful effect should be to activate the restoration of the skin, to accelerate metabolism and the process of cell division.
What does the term "fractional" mean?
During the cosmetic intervention, we can remove all changed substances.This effect is achieved, for example, during peeling when the acid affects the entire skin area.In this case, you have to prepare for a longer recovery and peel.There is a risk of complications during the deep peeling: chemical combustion can live with the formation of scars.The only reason why peeling in cosmetic salons is still actively used is a slight depth of the composition.With a sufficient superficial effect of the body's resources, there is enough to restore fabrics without scars and other problems.
In the case of laser effects, continuous damage to tissues leads to burns and associated complications.With the fractional laser exposure, you can stimulate the update of the epidermis and the dermis without serious negative follow, in which columns are generated with thermal injuries - microscopic tissue evaporation zones.Columns of thermal exposure are interspersed with unchanged skin areas, which creates optimal diseases for healing.At the same time, the “cascade” cytokin spread, which spreads in the microdamage focus on the entire series of epidermis and dermis, heals, tapered the skin and improves its appearance.
What is the difference between fractional, not possible rejuvenation and the rejuvenation of the fractional ablation?
A feature of the ablative laser is that the energy of their radiation is absorbed by water, which is abundant in both the dermis and in the epidermis.The result of the laser exposure is the destruction of cells of both layers of the skin, a strong reduction in the dermis and the introduction of the formation of a new collagen.
The ablative group of fractional lasers includes:
- Fractional co2 Laser with a wavelength of 10600 Nm;
- Fractional inheritance laser (he: yag, 2940 nm);
- Fractional Erbium laser on glass (er: Ysgg, 1790 Nm).
With their help, you can achieve a significant smoothing of skin relief and eliminate folds, hyper- and hypopigmentation.About 37% of the changes are removed from photography during treatment.The disadvantage of ablative fractional lasers is their rather aggressive effect on the tissue, which in 44% of patients with II-V photographs of the skin in Fitzpatrick leads to the development of post-inflammatory hyperpigmentation.
The radiation of the non -blatant fractional laser does not shave the epidermis, but mainly affects the dermis, which determines its softer and economical effect on the fabric.Neodymal (Nd: Yag, 1440 Nm), Erbiye (he, 1550 Nm), Tolevy Voloconny (1927 Nm) laser enable you to significantly improve and eliminate the skin structure.Laser methods make it possible to improve the skin color, remove pigment spots, remove the post-acne without trace of 51-75% of cases.At the same time, the risk of inflammatory hyperpigmentation is almost an order of magnitude lower.In patients with a photo type III, it is only 3%with IV-12%with V-33%.
Picose customers Alexandrite also belongs to the non-blank group of broken lasers.In addition, it has a characteristic property that determines higher efficiency and security compared to other laser laser rejuvenation procedures.
The duration of the picosecond pulse is a few ten times as much time for the fabrics for heating after exposure to the slight outbreak.The energy of the impulse is output for the destruction of cells contained melanin, while the surrounding tissue is not heated or damaged.In this way, in patients with a photo type of skin, without risk of getting complications, without having a risk of getting a risk without risk, without risk set up a risk, at any time without risk, in patients with a photodic skin type, at any time of the season without risk, at any time of the season to remove age spots, wrinkles and extended pores.
Picosecond impulses effectiveness ensures a unique nozzle, the lenses of which concentrate the energy of the laser radiation in hundreds of microlučej.This is similar to a "traditional" fractional rejuvenation, but the influence in every microlite is not thermally, but a photomechanical.In the middle of the impulse, this is a photomechanical "pressure" on the cells that are stronger than around the edges.For this reason, Cytokin "Cascades" plunge deep into the skin, the dermis and not on the sides - after the epidermis.The processes of regeneration, renewal and restoration of tissues are introduced there.
Due to the high speed of the laser in a short time, you can "process" a significant skin area.You no longer have to spend a long hour in the cosmetologist's office.The procedure for the elimination of age -related changes does not take longer than 15 minutes.
The unique advantages of the processes of fractional laser rejuvenation of the face:
- The main effect of the laser radiation falls on the dermis in which the alter pigment is destroyed in the process of treatment and active recovery processes are started.
- There is no usual rehabilitation with burns, peeling and crusts, after the procedure for 2-3 hours, an unspoken erythema can be observed that fits.
- The laser rejuvenation procedure in time takes about 15 minutes and is carried out without pain and symptoms.
The described skills of non -ambiguous rejuvenation by laser enable you to achieve a high degree of patient satisfaction, to avoid the risk of complications and to achieve a result that is comparable to ablation process, but without any damage to all layers of the skin.
