What is the principle of the laser hair removal system?

Laser hair removal is based on the principle of selective photothermodynamics, by reasonably adjusting the laser wavelength energy pulse width, the laser can pass through the surface layer to reach the root hair follicle of the hair. The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, so that the hair loses its ability to regenerate, and at the same time does not damage the surrounding tissues, and the pain is mild, laser hair removal is currently the safest, fastest and long-lasting hair removal technology.

Photon hair removal is a process in which the melanin in the hair follicle receives the fixed light emitted by the chest hair instrument, and converts the light energy into heat, damaging the hair follicle and blocking the hair development. The problem with the photons is that the energies are not very congruent, the absolute laser needs to be more than one time, and at the same time contains some of the remaining bands, and there is a pigment sedation effect. What it recovers is a wide spectrum (610-1000nm) of intense pulsed light, with a wide range of adjustable pulse width, which can stop permanent hair removal on all parts of the human body with different colors and depths.

Hello, the principle of laser hair removal: the melanin pigment in the hair follicle will absorb the energy of the laser, and destroy the hair follicle through the heat energy exchange generated, so that the hair will stop growing. Suitable for people:

People with light skin and fine and dark hair. Effect: Permanent hair removal by destroying hair follicles.

I don't know much about the selective absorption of melanin, I did a freezing point hair removal in Solan, and the effect is not bad, and I don't care about their principle.

The principle of laser hair removal is to destroy the hair follicle by generating heat in front of the laser to achieve the effect of hair loss. The specific operation process is to first remove the hair that needs the laser part with a scraper, so that the laser can better aim at the root of the hair, so as to go down the hair to the position of the hair follicle. This is where the heat generated by the laser comes into play to destroy the hair follicles, and this step can be repeated several times to achieve the final hair removal effect.

Laser hair removal is mainly based on selective photothermal action, which is rich in melanin in hair follicles and hair shafts, and the laser can selectively act on these melanins. When melanin absorbs energy, the temperature rises dramatically, destroying hair follicles and surrounding germinal stem cells, thus removing hair.

Notes:

1. Before the operation, the patient's past medical history should be carefully inquired about. 2. Appropriate eye protection should be done before the first day, including the patient, the operator and the indoor observer.

3. At the beginning of the **, the spot should be tested in an inconspicuous part first, and then a comprehensive ** should be carried out.

4. **The dosage should be appropriate.

5. Continuous use of cooling measures in the process.

6. Prevent wound infection, oral antibiotics if necessary.

7. If pigmentation occurs after **, it can fade or fade after a few months of local sunscreen care, and those with pigmentation can use hydroquinone cream externally.

From puberty onwards, the body grows some excessive or unwanted hair, such as excessive facial hair, leg hair, armpit hair, or excessive mid-length hand hair. Unwanted hair is a common beauty problem that puzzles both women and men. Traditional hair removal methods include shaving, mechanical hair removal, wax hair removal, chemical reagent hair removal, tweezers, etc., the common disadvantage is that it is difficult to destroy the hair matrix and hair follicle stem cells, and can only achieve the effect of temporary hair removal.

Although electrolysis and thermal dissolution can effectively destroy the sac, the disadvantages are cumbersome, time-consuming, inefficient, ineffective, painful, and may leave scars. The use of modern laser technology can not only achieve permanent hair removal or delay the time of hair regrowth, but also avoid and reduce the shortcomings of traditional hair removal techniques.

The above is today's sharing, I hope it can help you.

Human ** is a relatively translucent structure, under strong laser irradiation, ** is like a transparent paper, laser can penetrate**, it is easy to reach the skin sac, that is, the part of hair growth, and the melanin in the hair follicle can be burned to be converted into heat energy by the laser, so as to destroy the growth environment of the hair, that is, destroy the hair follicle, so as to achieve the purpose of removing the slag cilia.

If you want to use a laser hair removal device, you need to understand how it works. What is the principle of laser hair removal device? PChouse will take you to find out.

Laser hair removal is based on the photothermal principle of the laser, that is, the light energy of the laser penetrates the hair follicle and destroys the hair follicle. Laser in front of the first class, is a powerful energy, the role of the laser, can penetrate, can penetrate the hair follicle, into the hair follicle, so that the light energy of the laser into heat energy, so that the hair follicle dissolves, necrosis, and to achieve the effect of destroying the hair follicle, so that the hair follicle loses the ability to regenerate, and plays the role of hair removal. Laser is divided into a variety of wavelengths, and the 808 laser can be selected to generate high-energy heat, which directly acts on the depths of ** to absorb the melanin in the hair follicle, which has the effect of hair removal.

Laser hair removal is a relatively safe and popular method, and it can also avoid damage to the surrounding tissues. You need to go to a professional institution to operate, which can reduce the trauma to yourself. Therefore, the principle of laser hair removal, that is, the photothermal principle of laser, destroys the activity of hair follicles through photothermal action, and the principle of hair removal is achieved.
