Beauty salons generally use lasers, and household hair removal instruments generally use pulsed light. Pulsed light can be divided into intense pulsed light (IPL) and room pulsed light (HPL), in which the order of energy is laser > IPL > HPL. Although the principle of hair removal is the same, the energy is different, so the experience and effect of hair removal are different.

The laser is a single beam, which goes straight to the hair follicle, which is more accurate, so the hair removal effect is the best, but the pain is obvious. Many girls can't stand laser hair removal and bikini line.

IPL and HPL are light with a wavelength in a range, so the energy is more dispersed than laser. Although the hair removal effect is not as fast and obvious as that of laser, it is still good to stick to it. The key point is that the hair removal pain of pulsed light is much lower than that of laser hair removal, and HPL is an upgraded version of IPL, which shortens the emission speed of light and makes the peak energy per unit time reach higher, so the hair removal effect of HPL will be more moderate and efficient.

Because HPL is silk'n's patented technology in Israel, at present, only Glen and silk'n's hair removal instruments have adopted this technology, which is mild and painless, and is very suitable for women who are afraid of pain.
