1. what technology does hair removal work use?

Because there is abundant melanin in hair follicles and hair shafts, under the action of specific wavelength laser, melanin is used as the target color base. Under the condition that is compatible with the thermal damage time of the hair follicle tissue, the heat energy is transmitted to the hair follicle bulge and hair root through the protein in the hair shaft, causing irreversible damage to the hair follicle stem cells or the hair growth part of the hair papilla, thereby effectively destroying the hair follicle tissue, Reduce hair regrowth, delay regrowth and make regrowth hair thinner and lighter.

Because hair grows cyclically, it is divided into growth period, regression period and rest period. Laser hair removal is 75% effective in the growth phase of hair, 25% in the catagen phase, and almost ineffective in the resting phase. Therefore, it usually takes multiple treatments to achieve a nearly permanent hair removal effect.

2. What are the common laser hair removal instruments?

OPT hair removal device, 360 magneto-optical hair removal device, DPL hair removal device, 808 semiconductor hair removal device.

3. Who is not suitable for laser hair removal?

Laser hair removal is currently the main means of removing excess hair due to its convenience, safety and efficiency, but it is not suitable for everyone. The following types of people are not suitable for laser hair removal:

1. People with allergies or scar constitution;

2. Syphilis, AIDS, hepatitis, skin inflammation and infection;

3. Blood diseases and blood coagulation disorders;

4. Menstruating women;

5. Recently taking retinoic acid, vasodilator drugs, anti-arthritis drugs;

6. People who are allergic to hydroquinone or other bleaching agents.

7. Have used other methods (such as wax removal) for hair removal within 6 weeks.

8. Do skin color test, black skin is not suitable.

4. What are the hazards of illegal laser hair removal?

Laser hair removal must be carried out under reasonable parameters. There are strict data controls on the output energy, wavelength, light output speed, number of uses, and optical port density. Not everyone can operate it, and improper operation will be harmful:

1. Allergies. Some people's body skin is very sensitive. When using the hair removal device, you should pay special attention to the pulse frequency. The skin is very likely to have an allergic reaction when it is not operated properly.

2. Leave scars. Under normal circumstances, the skin will be red after laser hair removal. At this time, improper operation may cause burns and scars.

3. Inflammation. In the process of hair removal, if the disinfection and cleaning are not done well, it will easily lead to inflammation of the hair follicles and rough keratosis.

Therefore, formal medical beauty institutions, stable laser equipment and professional physicians are the prerequisites to ensure safety.
