Whether you want to take off the "sweaters" in winter, if you want to show perfect skin in summer, you must now take off your hair!

What is laser hair removal?

The laser is a single-wave, stable radiation beam whose divergence is very low and whose energy is high. Laser hair removal machine is based on the theory of selective photothermal effect. By appropriately adjusting the wavelength, energy and pulse width of the laser, the light from melanin can be absorbed and converted into heat energy to destroy the hair follicle tissue, thereby losing the ability to regenerate hair and achieving permanent hair removal without damaging the circumference. The pain was mild.

808 Semiconductor hair removal in the end, what is good?

Lasers commonly used for hair removal are:

Semiconductor laser wavelength 810 nm
Ruby laser wavelength of 694 nm
Alexandrite laser wavelength 755 NM
Garnet laser wavelength 1064 nm YAG
Intense Pulsed Light Wavelength 590-1200 NM

Laser hair removal prefers semiconductor lasers!

Semiconductor laser hair removal is currently a very ideal method for laser hair removal. Its wavelength is 810 nanometers, located in the near-infrared region of the spectrum, melanin absorption is good, but can also penetrate deep dermis and subcutaneous adipose tissue, affecting different parts and deep hair follicles, causing hair follicles to cause heat coagulation necrosis, so once and for all Part of the human body and to effectively remove the depth of the hair. Effectiveness.

Semiconductor hair removal benefits: permanent hair removal, no skin damage, the most advanced, most effective, safest, big body, large-scale hair removal, high efficiency, fast speed, no pain and so on.

Why does depilation require multiple treatments?

1. Hair growth is cyclic, d. H. From growth to regression to telogen and then to growth. Changing the growth cycle is a continuous process.

2. Hair, hair root and hair root contain much melanin in the growth phase, which after absorption of the laser energy can effectively destroy the hair follicles to achieve the purpose of hair removal.

3. During telogen and retrogression, there is little or almost no melanin in the hair root and hair root. The laser can not act on the hair follicle, so the treatment at this time is ineffective for the hair. The retrogression of the hair is usually 2 to 4 weeks and the telogen period 3 to 4 months.

In general, diode laser hair removal machine only work on growing hair, d. H. Only on the part of the hair that is currently visible on the body surface but not on dormant hair. After each treatment, the interval should be 1-1.5 months, and the second hair removal should be done after the hair has grown in the resting phase. Therefore, a single treatment can not completely solve the problem. In general, the hair can be reduced by more than 90% after 3-5 hair removal sessions, so that several treatments are usually required.

Applicability of semiconductor laser hair removal

Whether fine lip hair or rough beard, leg hair, bikini area (wearing bikini swimsuit exposed part) hair and body hair, the treatment area is small (less) only a few minutes, the treatment area is large (more) About half an hour, its efficiency, pain, and complaints are minor, complications are lower. No. It affects work, study, and life.

Precautions after laser hair removal

1. Cold compress: After the treatment, a slight burning sensation is felt at the treatment site and the hair follicle is blackened, zoomed or reddish. This is a normal reaction. If necessary, 10-15 minutes of local ice cream compress can be applied to alleviate or eliminate the phenomenon of red heat.

2. Excessive activities such as sun exposure, sauna steaming and massages should not be done within a week.

Note: Because each person's hair is different in thickness, color, and skin color, and the hairs of different parts of the same person are very different, professional doctors must choose appropriate and correct laser treatment parameters for the treatment. The quality of laser devices significantly affects hair removal, improper handling or the use of Shanzhai devices can even lead to discomfort and scalding.
