Laser hair removal is a technology based on the principle of selective photothermal kinetics. It reaches the hair follicle at the root of the hair through the skin surface, and the light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thus making the hair lose its regeneration ability without damaging the surrounding tissues and causing slight pain.
Laser hair removal can only achieve permanent hair removal if it is treated several times according to the individual's specific situation. The specific time of healing is related to many factors such as skin and hair quality. Generally speaking, laser permanent hair removal takes 3-5 times, and some people even have more times.
In fact, laser hair removal will not damage our skin.
This is because:
The human skin is a relatively light-transmitting structure. Clinical experiments by plastic surgeons have found that the skin is simply a transparent cellophane in front of a powerful laser, so the laser can penetrate the skin smoothly and reach the hair follicle. Because there is more melanin in hair follicle, it can preferentially absorb a large amount of laser energy and finally convert it into heat energy, thus increasing the temperature of hair follicle and destroying the function of hair follicle.
In this process, because the skin relatively does not absorb laser energy, or absorbs a small amount of laser energy, the skin itself will not be damaged.
Moreover, the laser removed by laser only acts on melanin in hair follicles, but there is no melanin in sweat glands, so it will not absorb laser power, damage sweat glands and have no other adverse effects on human body.
General laser hair removal instruments are certified by international authoritative organizations and have been successfully treated for tens of thousands of times in the world. Laser hair removal treatment process is simple and fast. Before the operation, the hair on the surface of the treatment site was shaved, so that it could not absorb the laser. Laser acts on the skin surface through a complex optical fiber transmission system. Laser energy is selectively absorbed by melanin in hair follicles and converted into heat energy to destroy hair follicles without causing damage to surrounding skin.
Therefore, laser hair removal is very safe as long as you choose a good hospital and doctor. However, although laser hair removal can achieve long-term hair removal, it cannot be permanently removed. Over time, body hair may grow back like leeks. Moreover, body hair is used to sweat. If it is completely removed, the cooling conditions of the body will be reduced, and it is easier to feel internal heat in summer, and the toxins in the body are not conducive to elimination. Therefore, friends who need laser hair removal should carefully consider it.
