Laser rejuvenation is an effective and scientifically proven technique. The beneficial effect of a laser on a particular target molecule has been scientifically proven and tested over and over again.
Laser rejuvenation is a procedure shrouded in many myths. Some say it's great at helping treat many skin blemishes, while others are skeptical that it isn't. Moreover, it is not a fact that either has actually undergone a laser, nor an 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 only absorbed by certain molecules. This:
- 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 in injury, therefore, it begins to rely on the missing elements. New cells, new proteins of the 3D framework of the skin are synthesized, the integumentary tissue is tightened, smoothed and the radiance returns to it.
If the laser beams were beams, with a distance between the beams (split techniques), then micro-depressions appear in the skin. The fabric tries to connect the edges of these grooves - and so 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 effect described is typical of any type of laser. But this is where the rejuvenation only ends with the CO2 laser. Neodymium and the dye laser also eliminate all visible vessels: rosacea, dilated veins, wine stains, spider veins.
Will there be no effect?
Laser rejuvenation is a scientifically based technique, it can only have an effect. Let's explain: every target molecule of the laser 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 - how else would the skin be nourished. Maybe, maybe, not having melanin - but that's only in people with albinism.
The effect of a laser on a particular target has been scientifically proven and tested over and over again. This is not a blind introduction of the drug - focusing only on the external signs of hyaluronic acid or collagen deficiency. This is a deliberate launching of aseptic (non-microbial) inflammation of the skin, to which the response 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 the impulses are not sent near the nerve endings, but into the microvessels.
If you undergo the procedure on an alexandrite picosecond laser, which sends pulses 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 no heating occurs, that is, it is the cause of pain.
How does rejuvenation take place? Pulses several picoseconds long have a mechanical effect (microexplosions of skin scaffolding proteins). This triggers the formation of certain substances - cytokines, which carry information from one cell to another. They support the processes of skin remodeling for a long time.
