Laser hair removal and freezing point hair removal are two different hair removal methods. Based on the principle of hair removal, we need to understand the classification of hair removal instruments, as well as the types of hair, and analyze the advantages and disadvantages of the two.
1. The principle of hair removal
Black things will absorb light of a certain color. After absorbing light, it will become heat. After becoming hot, the black things will be destroyed. Our hair follicles are black and will also absorb light. The heat generated after absorbing light will destroy it. This black hair follicle finally falls off naturally, and after falling off naturally, the purpose of hair removal is achieved.
2. Classification of hair removal instruments
At present, there are roughly two types of light used for hair removal, one is laser, the other is photon,Laser hair removal instruments generally only have one wavelength of light (currently using 810nm wavelength light, which is also used in hospitals, which is the gold standard for hair removal), it is not like photon hair removal when used.
It is still very dazzling to wear sunglasses. For home laser hair removal, you should not wear sunglasses. The most important thing is that the energy density is higher than that of photons, which can remove thick black hair or beard.
The wavelength of the photon hair removal device is generally a series of wavelengths of 530-1200nm, some of which are used for hair removal, some are useless, some are harmful, some will be absorbed by the skin and cause dull skin, some Some can be cosmetic, because they are not a single type of light specially used for hair removal, so the light they emit is scattered and the energy is not concentrated, so the energy density will be much lower than that of lasers.
Freezing point hair removal device, the freezing point here only means cooling, because when the light energy is converted into heat during hair removal, it may be painful. With the freezing point, cooling the skin will make the skin more comfortable, that's all, is there a freezing point, and hair removal The effect is irrelevant, and the hair removal effect is related to the level of energy density.
Freezing point hair removal, it can be freezing point laser hair removal, or freezing point photon hair removal.
3. Types of hair
If it is to remove thick black hair, such as beard, please use laser, if it is soft and slightly lighter hair, you can use photon hair removal.
