Theory of picosecond laser machine:

The PicoSecond Laser uses ultra-short pulses (one trillionth of a second in length) to hit the melanin with a great pressure, the melanin shatters into tiny dust-like particles. Because the particles are so small, they are more readily absorbed and eliminated by the body. This can mean better clearance of the melanin and less treatments overall.
 
PicoSecond Laser is a quick and easy non-surgical, non-invasive laser skin treatment for the body including chest or decollete, face, hands, legs, and more.
 
Using the latest technologies, the latest Picosecond laser, it has never been easier and quicker to remove spots and unwanted tattoos. Pigment and tattoo removal technology has truly come a long way. A significant amount of research and development has led to the launch of Picolaser, the most talked about laser in the cosmetic industry.

Pigment clear rate is higher
Pigment removal speed is faster
Refused to stimulate melanin active again risk
Remove melanin colleagues and start repair mechanism
Won't damage the normal tissue
