Laser rejuvenation is a scientifically proven effective technique. The beneficial effect of a laser on a certain target molecule has been proven and tested many times scientifically.
Laser rejuvenation is a multi-faceted procedure. Some say it is great for helping treat many skin blemishes, while others are skeptical that it is not. Furthermore, it is not a fact that one or the other has undergone a laser, and not an IPL procedure. So what exactly is it? Does laser rejuvenation help or not?
Rejuvenation, what can a laser do?
Laser treatments are the effect on the skin of such light radiation, which is absorbed by only a few molecules. Ajo:
- intercellular and extracellular water - for a CO2 laser;
- oxyhemoglobin, collagen and elastin proteins - for neodymium laser;
- hemoglobin and melanin - for laser dye;
- melanin - for diode and alexandrite lasers.
By absorbing light, the desired molecule converts it into heat and, under the influence of the latter, decomposes. This involves in the skin the same response that occurs to the injury, as a result, it begins to build on the missing elements. New cells, new proteins of the 3D frame of the skin are synthesized - the integral tissue tightens, softens and the glow returns to it.
If the laser beams were beam, with a distance between the beams (fractional techniques), then microdepression appears on the skin. Tissues try to connect the ends of these grooves - and thus the area of wounds and stretch marks is reduced. And when the cells that contain the pigment melanin (the one whose accumulations lead to the appearance of age spots) heat up, the natural dye is excreted from the lymphatic system.
The effect described is typical for any type of laser. But here the renewal ends only with the CO2 laser. Neodymium and color laser can also remove any visible vessels: rosacea, varicose veins, wine stains, spider veins.
Will there be no effect?
Laser rejuvenation is a scientifically based technique, it can not have no effect. Let us explain: every laser target molecule is in our skin. We form collagen and elastin, otherwise the skin could not be on the surface, but would slide down. We also have hemoglobin with oxyhemoglobin in our vessels - otherwise, how would the skin be nourished. Maybe, maybe, there is no melanin - but that is only in people with albinism.
The effect of a laser on a given target has been proven and tested many times scientifically. This is not a blind presentation of the drug - focusing only on the outward signs of hyaluronic acid or collagen deficiency. This is a deliberate initiation of aseptic (non-microbial) inflammation in the skin, the answer to which is always the same: the production of its new elements.
Does laser rejuvenation hurt?
Not always. If the procedure is performed using a CO2 laser, which vaporizes the skin columns, then anesthesia is required - up to general anesthesia. If you go for rejuvenation with a neodymium laser, the procedure is almost painless, as there is no trauma to the epidermis, and the impulses are sent not near the nerve endings, but to the microenvironment.
If you undergo the procedure with an alexandrite laser, which sends impulses under the skin 100 times shorter than in other devices, then there will be no pain at all. Why? The fact is that with such a short pulse duration, heating does not occur - that is, it is the cause of pain.
How then does renewal occur? Pulses a few pixos long have a mechanical effect (micro-explosions of skin scalp proteins). This causes the formation of several substances - cytokines, which transmit information from one cell to another. They support skin remodeling processes for a long time.
