Laser rejuvenation is an effective scientifically proven technique. The beneficial effect of a laser on a particular target molecule has been scientifically proven and tested many times.
Laser rejuvenation is a procedure shrouded in many myths. Some say that it is great for dealing with a variety of skin blemishes, while others are skeptical that it is not. Moreover, it is not a fact that one or the other really went through the laser, and not the IPL procedure. So what is it really? 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 only by certain molecules. It:
- intracellular and extracellular water - for a CO2 laser;
- oxyhemoglobin, collagen and elastin proteins - for neodymium laser;
- hemoglobin and melanin - for dye laser;
- 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 includes in the skin the same response that occurs to injury, as a result, it begins to build on the missing elements. New cells are synthesized, new proteins of the 3D-skeleton of the skin - the integumentary tissue is tightened, smoothed, and the radiance returns to it.
If the laser beams were beam, with a distance between the beams (fractional techniques), then microdepressions appear in the skin. The tissue tries to connect the edges of these grooves - and thus the area of scars and stretch marks is reduced. And when the cells containing the melanin pigment (the one whose accumulations lead to the appearance of age spots) are heated, the natural dye is excreted by the lymphatic system.
The described effect is typical for any type of laser. But this is where the rejuvenation ends only with the CO2 laser. Neodymium and dye laser can also remove any visible vessels: rosacea, dilated veins, wine stains, spider veins.
Will there be no effect?
Laser rejuvenation is a scientifically based technique, it cannot but have an effect. Let's explain: any laser target molecule is in our skin. We form collagen and elastin, otherwise the skin would not be able to 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, perhaps, not to have melanin - but this is only in people with albinism.
The effect of a laser on a particular target has been scientifically proven and tested many times. This is not a blind introduction of the drug - focusing only on external signs of hyaluronic acid or collagen deficiency. This is a deliberate launch 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 carried out using a CO2 laser, which evaporates the columns of the skin, then anesthesia is required - up to general anesthesia. If you resort to rejuvenation with a neodymium laser, the procedure is almost painless, since there is no trauma to the epidermis, and impulses are sent not near the nerve endings, but into the microvessels.
If you undergo the procedure on a picosecond alexandrite laser, which sends impulses under the skin 100 times shorter than on 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 - namely, it is the cause of pain.
How then does rejuvenation take place? Pulses several picoseconds long have a mechanical effect (microexplosions of skin scaffold proteins). This triggers the formation of certain substances - cytokines, which transmit information from one cell to another. They support the skin remodeling processes for a long time.
