Laser rejuvenation is an effective scientifically proven technique. The beneficial effect of the laser on a specific target molecule has been scientifically proven and tested many times.
Laser rejuvenation is a procedure shrouded in many myths. Some say it's great for dealing with a lot of skin blemishes, while others are skeptical that it's not. Furthermore, 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 procedures are the effect on the skin of such light radiation, which is absorbed only by certain molecules. That:
- intracellular and extracellular water - for CO2 laser;
- oxyhemoglobin, collagen and elastin proteins - for neodymium laser;
- hemoglobin and melanin - for dye laser;
- melanin - for diode and alexandrite lasers.
Absorbing light, the desired molecule converts it into heat and under the influence of the latter decomposes. This involves the same reaction in the skin that occurs with an injury, as a result of which it begins to build up on the missing elements. New cells are synthesized, new proteins from the 3D frame of the skin - the covering tissue is tightened, smoothed and the radiance is restored.
If the laser beams were a 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 reduces the area of scars and stretch marks. And when the cells containing the melanin pigment (the one whose accumulation leads to the appearance of age spots) are heated, the natural dye is released from the lymphatic system.
The described effect is characteristic of each type of laser. But here the rejuvenation ends only with the CO2 laser. The neodymium laser and the dye can also remove all visible vessels: rosacea, varicose veins, wine stains, spider veins.
Is there no effect?
Laser rejuvenation is a scientifically based technique, it can not but have an effect. Let's explain: every molecule of a laser target 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, no melanin - but that's only for people with albinism.
The effect of the laser on a specific 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 start 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 that evaporates the skin columns, then anesthesia is needed - up to general anesthesia. If you resort to 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 in the microvessels.
If you undergo the procedure with a picosecond alexandrite laser, which sends pulses under the skin 100 times shorter than on other devices, then there will be no pain. Why? The fact is that with such a short pulse duration, no heating occurs - this is the cause of pain.
How then does rejuvenation happen? The pulses with a length of a few picoseconds have a mechanical effect (microexplosions of proteins from the skin skeleton). This causes the formation of certain substances - cytokines, which transmit information from one cell to another. Support skin remodeling processes for a long time.
