How to choose an effective hair removal device?
To choose a good hair removal device, energy and wavelength are particularly important. Usually, the higher of energy and the longer of wavelength, the more significant the hair removal effect will be. But it must also be within the acceptable range of human skin; the second is the light speed and freezing point function, the faster the light-emitting speed, the higher the efficiency of hair removal, and the freezing point is to reduce the pain, because the higher the energy, the stronger the corresponding pain.
Energy is very important for a hair removal device. Everyone knows that the hair removal speed of a laser hair removal device in a beauty salon is faster and has a better effect than a home hair removal device. This is because the energy of the laser hair removal device is higher than that of the home hair removal device. The energy of the instrument is much larger, that is to say, the higher the energy density under the same conditions, the more significant and lasting effect of hair removal. But as the energy increases, the pain will be relatively stronger, but it also varies from person to person, because each person has different skin pain tolerance.
Wavelength is also a very important concern when choosing a hair removal instrument. The wavelength of strong pulsed light is mainly used in the field of beauty and the treatment of various skin diseases. The longer of wavelength, the deeper of skin layer can be intervened. Generally speaking, the wavelength of 510nm-1200nm has a good hair removal effect. Therefore, we do not recommend that you buy a hair removal device with a wavelength below 500nm. Not only does it have no hair removal effect, but it will seriously endanger our health.
(3) Light flash speed
The faster of light emission speed of the hair removal device, the higher the efficiency of hair removal. Therefore, if you want to remove hair quickly, in addition to the previous two factors, you must also choose a hair removal device with a faster light output speed. The faster the light output speed, the better the efficiency of hair removal. Higher.
(4) Freezing point function
The freezing point function is to reduce pain. Some people are more sensitive to pain. Ladies who are afraid of pain must choose a hair removal device with a freezing point function. You must know that melanin has the ability to absorb light. Asian skin is generally yellowish, and the content of melanin will be higher. Therefore, during hair removal, light energy is easily absorbed by the skin epidermis. If the freezing point function is not used, most people will have strong pain, and the freezing point function is enough to reduce the high-intensity energy light absorbed by the skin The burning sensation can protect the skin and reduce the pain.
