What does laser hair removal need to know

With the advent of summer, fashionable summer clothes can best show the unique charm of women, but many women are very worried that there are too many hairs on the exposed parts, so that they are embarrassed or dare not wear their favorite summer clothes. Yes, every beauty loving lady wants to have a bright and clean skin like jade. Excess hair not only seriously affects beauty, but also brings spiritual pain. Removing excess hair is not only an important part of people’s pursuit of body beauty, but also an important means to remove psychological obstacles and regain self-confidence.

At present, the most ideal and scientific hair removal method is laser hair removal. Laser hair removal is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength and energy pulse width, the laser can pass through the surface of the skin to the root hair follicle of the hair. The light energy is absorbed and transformed into heat energy that destroys the hair follicle tissue, so as to make the hair lose the regeneration ability without damaging the surrounding tissue and slight pain.

Only in the growth period, the hair ball of the hair, that is, the hair root is in the hair follicle, and the hair ball is full and melanin is dense, which can absorb a lot of laser energy and destroy the hair follicle. In the degenerative period and the resting period, the hair root has been removed from the hair follicle, and the melanin contained in the hair follicle is also greatly reduced. Therefore, the hair follicles in these two periods are almost not damaged after being irradiated by the laser. After they enter the growth period again, they can continue to grow. At this time, it needs a second irradiation to remove it.

In addition, in a hair area, only about 1 / 3 of the hair is in the growth period at the same time, so generally, about 1 / 3 of the hair can be removed by one depilation, and the depilation course is more than 3 times.

What side effects does laser hair removal have

It can be seen from the principle of laser hair removal that laser only destroys black substances, such as hair and hair follicles, and other parts of the skin are safe. Therefore, it is very safe to use qualified machines for laser hair removal under correct operation.

Is laser hair removal harmful to the skin

The skin of human body is a relatively transparent structure. The clinical experiment of experts found that in front of powerful laser, the skin is just a piece of transparent cellophane, so the laser can pass through the skin very smoothly and reach the hair follicle. Because there is a lot of melanin in the hair follicle, it can first absorb a large amount of laser energy and finally convert it into heat energy to raise the temperature of the hair follicle, Achieve the purpose of destroying hair follicle function. In this process, because the skin does not absorb laser energy, or absorbs a small amount of laser energy, the skin itself will not be damaged.

Will laser hair removal affect perspiration

The laser of laser hair removal only acts on the melanin in the hair follicle, while there is no melanin in the sweat gland, so it will not absorb the laser ability and damage the sweat gland, and has no other adverse effects on the human body. Therefore, after laser hair removal, it will not affect the ability of perspiration.

Laser hair removal steps:

  1. Skin preparation

The term is skin preparation, which is called shaving in popular words, that is, use a disposable hair removal knife to scrape all the sweat hair on the body surface of both arms, so that when hair removal is carried out, light waves can act on the root of hair follicles. Before preparing the skin, please keep the depilation clean to ensure the effect.

  1. Laser hair removal

The strength is evenly absorbed and contacted at the depilation place, so that the light wave can thoroughly “encircle and suppress” the root of the hair. When the intensity of light increases, the skin will feel stronger and stronger.
