Laser rejuvenation is a scientifically proven effective technique. The beneficial effect of a laser on a particular target molecule has been scientifically proven and tested many times over.
Laser rejuvenation is a procedure shrouded in many myths. Some say it's great for helping deal with many skin blemishes, while others are skeptical that it isn't. It is also not a given that either of them actually underwent a laser and not 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 this 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 the injury, as a result, it begins to build on the missing elements. New cells are synthesized, new proteins of the 3D structure of the skin: the integumentary tissue is stretched, smoothed and its radiance is restored.
If the laser beams were rays, with a distance between the beams (fractional techniques), 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 melanic pigment (the one whose accumulations lead to the appearance of age spots) warm up, 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, varicose veins.
Will there be no effect?
Laser rejuvenation is a scientifically based technique, it can only have an effect. Let's explain: Any laser target molecule is in our skin. We form collagen and elastin, otherwise the skin could not stay on the surface, but would slide downwards. We also have hemoglobin with oxyhemoglobin in our blood vessels, otherwise how it would feed the skin. Maybe, maybe not having 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 over. 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 launch of aseptic (non-microbial) inflammation into 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, which evaporates the skin columns, anesthesia is required - up to general anesthesia. If rejuvenation with a neodymium laser is used, the procedure is almost painless, since 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 on a picosecond alexandrite laser, which sends pulses under the skin 100 times shorter than other devices, there will be no pain. Why? The fact is that with such a short pulse duration, heating does not occur, that is, it is the cause of pain.
How then does rejuvenation take place? Long pulses several picoseconds have a mechanical effect (micro-explosions 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.
