Laser rejuvenation is a scientifically proven effective method. The beneficial effects of a laser on a specific target molecule have been scientifically proven and repeatedly tested.
Laser rejuvenation is a procedure covered in many myths. Some say it's great for helping to deal with many skin blemishes, while others are skeptical that it isn't. Moreover, it is not an IPL procedure for one or the other, it is not a fact that they are actually exposed to the laser. But what is it really? Does laser rejuvenation help or not?
Rejuvenation, what can a laser do?
Laser treatment is the effect of such light radiation on the skin, which is absorbed only by certain molecules. O:
- intracellular and extracellular water - for CO2 laser;
- oxyhemoglobin, collagen and elastin proteins - for neodymium lasers;
- hemoglobin and melanin - for dye lasers;
- melanin - for diode and alexandrite lasers.
By absorbing light, any molecule converts it into heat and decomposes under the influence of the latter. It involves the same reaction that occurs when the skin is damaged, as a result of which it begins to build on the missing elements. New cells, new proteins in the skin's 3D frame, are synthesized - the integumentary tissue is stretched, smoothed and radiance returns to it.
If the laser beam was a beam, the distance between the beams (fractional methods), then microdepressions appear on the skin. The tissue tries to connect the edges of these grooves - thus reducing the area of scars and stretch marks. When cells containing melanin pigment (accumulation of which causes the appearance of age spots) are heated, the natural dye is released by the lymphatic system.
The described effect is typical for any type of laser. But here the rejuvenation ends only with a CO2 laser. Neodymium and dye lasers can also remove any visible veins: rosacea, dilated veins, wine stains, spider veins.
Will there be no effect?
Laser rejuvenation is a science-based technique that cannot be without its effects. Let's explain: any laser target molecule is in our skin. We form collagen and elastin, otherwise the skin will not be on the surface, but will slide down. Our arteries also contain oxyhemoglobin-containing hemoglobin - otherwise how would the skin be nourished. Maybe not melanin - but this only happens in people with albinism.
The effect of a laser on a specific target has been scientifically proven and repeatedly tested. This is not a blind application of the drug - just pay attention to the external signs of hyaluronic acid or collagen deficiency. This is a deliberate onset of aseptic (non-microbial) inflammation of the skin, the answer is always the same: the production of its new elements.
Does laser rejuvenation hurt?
Not always. If the procedure uses a CO2 laser that evaporates the skin columns, anesthesia is required - up to general anesthesia. If you apply a rejuvenation with a neodymium laser, the procedure is almost painless, because there is no trauma to the epidermis, and the impulses are sent to the microvascular, not to the nerve endings.
If you undergo the procedure with a picosecond alexandrite laser, which sends impulses 100 times shorter under the skin than other devices, then there will be no pain. Why? The fact is that heat does not occur with such a short pulse duration - that is, the cause of pain.
How does rejuvenation happen? Several picosecond pulses have a mechanical effect (microparticles of skin skeletal proteins). This causes the formation of certain substances called cytokines that transmit information from one cell to another. They support the process of skin reconstruction for a long time.
