Principle of picosecond laser 

The principle of laser freckle is that the skin melanin particles will absorb specific light waves, so the use of a specific wavelength of laser can act on the melanin particles, so that it can produce a photomechanical effect: that is, when the laser treatment is used, the high-energy light can produce a high-impact shock wave, which is used to crush the large group of melanin into powder. The large group of melanin is scattered in the skin after being broken, the naked eye looks like there is no stain, and the broken melanin is easier to be metabolized by the stratum corneum and the blood circulation lymphatic cycle because of its smaller size.

Picosecond laser advantages

1. Shorter time and faster speed
2, honeycomb lens can make the energy more concentrated
3, unique wavelength, remove melanin effect is good
4, not easy to damage the skin
5, don’t worry about anti-black effect
