Laser Beauty Machine Supplier - Beauty Equipment ManufactureHow to judge the quality of laser hair removal instrument-Beijing Zhenhuimei Beauty Equipment Co., Ltd.
How to know the advantages and disadvantages of laser hair removal device? First of all, as a modern instrument, like a mobile phone, you can see the performance parameters of the graphics card, running memory, etc. to judge the mobile phone The advantages and disadvantages are the same, and the laser hair removal instrument can also be easily distinguished according to certain parameters. But as a beauty instrument, the most important thing is to look at the actual effect!
Six factors affecting the effect of laser hair removal
Wavelength
Most of the wavelength bands of laser hair removal instruments used in clinical medicine are between 694-1200 meters, which can be well absorbed by hair follicles and melanin in hair Absorbs while ensuring deep penetration into hair follicles. At present, semiconductor laser hair removal device (wavelength 800-810nm), long pulse (wavelength 1064nm) are the most clinically used widely.
Pulse width
The ideal pulse width of laser hair removal ranges from 10 to 100 milliseconds, the pulse width of long pulse OPT hair removal instrument (5~50ms) or even longer, and the 808nm semiconductor laser hair removal Meter pulse width (8 ~ 720 milliseconds). Gently heats and destroys the hair follicle and the bulge that contains the hair follicle stem cells. At the same time, it can avoid skin damage caused by a sudden rise in temperature after absorbing light energy. For people with darker skin, the pulse width can even be increased to hundreds of milliseconds, which is safer.
Cooling unit
The long-pulse OPT hair removal device has a semiconductor cooling head, and the 808 nm freezing point semiconductor laser hair removal device has a contact cooling head and a sapphire cooling window. It can protect the epidermis more effectively during treatment and safely treat the epilator with high energy density.
Security
Laser generator of , high stability and long service life. The effective light emission can reach 20 million times, and the hair removal is more thorough. The imported water and electricity integrated quick connector has stable energy transmission and long service life. The automatic water flow, water level and water temperature alarm system can prevent any danger at the first time.
Long pulse OTP laser hair removal treatment instrument adopts imported long pulse laser generator, which has high stability, long life and good curative effect. The 3000w laser power pump ensures the stability of high output and high frequency output.
Number of treatments
It takes several times for hair removal treatment to achieve the desired effect, and the number of times of hair removal is positively correlated with the effect of hair removal. Usually it takes 3-5 times.
There are two reasons:
1, is that most hair follicles come together in groups of three and open in the same pore where one hair grows from one of the three follicles in the lower group, so one treatment only Can destroy a hair follicle.
2, Hair is divided into three periods: growth period, catagen period and telogen period. The hair in the growth period has the most melanin. The energy emitted by the laser hair removal device only destroys the hair follicles in the growth period, and has no obvious effect on the hair in the degenerative and resting periods. Therefore, the laser does not work before these hairs enter the growth period. Laser hair removal Multiple treatments are required for obvious results.
