Intensive pulsed light sources emit a series of high-energy intense pulsed light, including visible light and near-infrared light,at different wavelengths (between 470nm and 1,200nm). When different wavelengths of light are simultaneously projected on the skin tissue, they can penetrate different layers of the skin tissue. When part of the light is absorbed and turned into heat energy, it can achieve the effect of beauty or hair removal.

 Taking hair removal as an example, when the released light energy is absorbed by melanin or other chromophores in the hair, the temperature of the hair follicles is rising to bring damage to the hair in growth , which can reduce hair regrowth and achieve hair removal effect.

However, hair grows from the hair follicle, and each hair follicle has its own individual growth cycle, it goes through three stages of the cycle: growth phase, recession and rest period. One time of hair removal can only remove part of the hair. When the hair follicle enters another growth cycle, it will grow new hair, so it may not be able to permanently remove hair(only by one time).

At present, many electronic beauty products brands have launched home IPL hair removal instruments, Although the home IPL hair removal device is usually accompanied by instructions to teach how to use the hair removal device, the general public has not received relevant training. Care should be taken. Read the product manual and applicable scope before use, and pay attention to whether there is contact on the machine, like Contact sensor, UV filter, power switch control, etc.so to prevent misuse of safety facilities. Also pay attention to whether the machine is suitable for the face and whether you need to wear eye protection. If the IPL hair removal device is operated under inadvertent touch, it may damage the eyes and damage your eyesight. Ideally, whether you go to a beauty salon or purchase an IPL machine for hair removal, you should first consult a professional health care to find out if you are suitable for using the relevant hair removal method.
