How to choose an effective hair removal device

If you want to choose a good hair removal device, energy and wavelength are particularly important. Relatively speaking, the higher the energy and the longer the wavelength, the more significant the hair removal effect will be, but it should also be within the acceptable range of human skin; the second is the light output speed and freezing point. Function, the faster the light output, the higher the hair removal efficiency, and the freezing point is to reduce the pain, because the higher the energy, the stronger the corresponding pain.

 

(1) Energy

 

Energy is a very important point for hair removal devices. I think everyone knows that laser hair removal devices in beauty salons will remove hair faster and better than household hair removal devices. This is because the energy of laser hair removal devices is higher than that of household hair removal devices. 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 the hair removal effect will be. However, as the energy increases, the pain will be relatively stronger, but it also varies from person to person, because everyone's pain tolerance to the skin is different.

 

(2) Wavelength

 

Wavelength is also a very important concern for selecting a hair removal device. The wavelength of intense pulsed light is mainly used in the field of beauty to treat various skin diseases. The longer the wavelength, the deeper the 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 510nm. Not only does it have no hair removal effect, but it will seriously endanger our health.

 

(3) Light output speed

 

The faster the light output 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 should also choose a hair removal device with a faster light output speed. The faster the light output speed, the higher 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. Sisters 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. Asians generally have yellowish skin, and the content of melanin will be more. 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 a strong sense of pain, and the freezing point function is enough to reduce the high-intensity energy after the light is absorbed by the skin. The burning sensation it brings protects the skin and reduces pain.
