Laser rejuvenation is an effective scientifically proven technique. The beneficial effects of lasers on a specific target molecule have been scientifically proven and tested many times.
Laser rejuvenation is a procedure shrouded in many myths. Some say it’s great for dealing with many blemishes on the skin, while others are skeptical it isn’t. Moreover, it is not a fact that one or the other was actually subjected to 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 action on the skin of such light radiation that is absorbed only by certain molecules. To:
- intracellular and extracellular water - for CO2 laser;
- oxyhemoglobin, collagen and elastin proteins - for neodymium laser;
- hemoglobin and melanin - for color laser;
- melanin - for diode and alexandrite lasers.
By absorbing light, the desired molecule converts it into heat and under the influence of the latter it decays. This involves in the skin the same response that occurs to an injury, as a result, it begins to build on the missing elements. New cells are synthesized, new proteins of the 3D frame of the skin - the covering tissue is tightened, smoothed and its radiance is restored.
If the laser beams were a beam, with a gap between the beams (fractional techniques), then microdepressions appear on the skin. The tissue tries to connect the edges of these grooves - and thus reduces the area of scars and stretch marks. And when the cells that contain the pigment melanin (the one whose accumulations lead to the appearance of age spots) heat up, the natural color is secreted by the lymphatic system.
The described effect is typical for any type of laser. But here rejuvenation ends only with a CO2 laser. Neodymium and dye laser can also remove all visible blood vessels: rosacea, varicose veins, wine stains, spider veins.
Will there be no effect?
Laser rejuvenation is a science-based technique, it can't help but work. Let's explain: any 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 blood vessels - otherwise, to nourish the skin. Maybe, maybe, not have melanin - but that’s only in people with albinism.
The effect of lasers on a specific target has been scientifically proven and tested many times. This is not a blind introduction of the drug - focusing only on the external signs of hyaluronic acid or collagen deficiency. This is the 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 with a CO2 laser, which evaporates the pillars of the skin, then anesthesia is needed - until general anesthesia. If you resort to neodymium laser rejuvenation, the procedure is almost painless, because there is no trauma to the epidermis, and the impulses are not sent near the nerve endings, but in the microvessels.
If you undergo the procedure on a picosecond alexandrite 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, there is no heating - namely, it is the cause of pain.
How then does rejuvenation occur? Pulses lasting several picoseconds have a mechanical effect (microexplosions of skin scaffold proteins). This triggers the creation of certain substances - cytokines, which transfer information from one cell to another. They support skin remodeling processes for a long time.
