Laser skin rejuvenation is an effective technology that has been scientifically proven. The beneficial effect of laser on specific target molecules has been scientifically proven and tested many times.
Laser skin rejuvenation is a process shrouded in many myths. Some people say it helps deal with many skin blemishes, while others suspect it is not. In addition, it is not true that one or the other actually received the laser instead of the IPL procedure. So what exactly is it? Is laser skin rejuvenation useful?
What can laser do in rejuvenation?
Laser treatment is the effect of this light radiation on the skin, which can only be absorbed by certain molecules. it:
- Intracellular and extracellular water-for CO2 laser;
- Oxyhemoglobin, collagen and elastin-for neodymium laser;
- Hemoglobin and melanin-for dye laser;
- Melanin-used in diodes and alexandrite lasers.
By absorbing light, the desired molecules convert it into heat and decompose under the influence of the latter. This includes the same reaction that occurs in the skin as an injury, so it starts to build on the missing elements. New cells, new proteins of the skin's 3D framework are synthesized-the outer skin tissue is tightened, smoothed, and restored to its brilliance.
If the laser beam is a beam and there is a certain distance between the beams (fractional technique), then micro depressions will appear in the skin. The tissue tries to connect the edges of these grooves-thereby reducing the area of scars and stretch marks. When cells containing melanin (the accumulation of which leads to the appearance of age spots) are heated, the natural dye is excreted by the lymphatic system.
The described effects are typical for any type of laser. But this is where only the use of CO2 lasers can rejuvenate. Neodymium and dye lasers can also remove any visible blood vessels: rosacea, dilated veins, wine stains, spider veins.
Will it have an impact?
Laser skin rejuvenation is a scientifically based technology, and it has to produce results. Let us 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 slip off. We also have hemoglobin and oxygenated hemoglobin in our blood vessels-otherwise, how the skin will be nourished. Maybe, maybe, there is no melanin-but this only applies to people with albinism.
The effect of laser on specific targets has been scientifically proven and tested many times. This is not a blind introduction to drugs-just focus on the external signs of hyaluronic acid or collagen deficiency. This is deliberately causing sterile (non-microbial) inflammation in the skin, and the answer is always the same: the production of new elements.
Is laser skin rejuvenation harmful?
Not always. If the operation is performed with a CO2 laser, which will evaporate the skin column, anesthesia is required-up to general anesthesia. If you use a neodymium laser for rejuvenation, the process is almost painless because the epidermis is not traumatized, and the pulses are not sent near the nerve endings, but sent to the capillaries.
If you perform surgery on a picosecond alexandrite laser, which sends pulses under the skin 100 times shorter than other devices, you will not feel pain at all. Why? The fact is that with such a short pulse duration, fever does not occur—that is, fever is the cause of pain.
So how does rejuvenation happen? Pulses of a few picoseconds long have a mechanical effect (micro-explosion 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 process for a long time.
