The role of picoseconds
Cosmetic picosecond means the use of picosecond laser to achieve cosmetic effects. Picosecond laser is a relatively advanced laser. Picosecond is a time unit, indicating that the time is very short. Laser beauty mainly uses a certain energy beam to hit the skin. Damaged pigment cells in the dermis. However, the laser does not continuously emit energy beams to the dermis layer. There will be an interval between different energy beams hitting the dermis layer of the skin. The unit of this time interval is picoseconds, indicating that the time interval is very short, and a short time interval can make The high-energy laser beam hits the pigment cells of the skin, and the pigment cells are quickly damaged in a short period of time. At the same time, the relatively high energy in a short period of time can effectively damage the pigment cells, and the damage to the normal tissue is relatively small, so it is the biggest advantage of the picosecond laser. And so on the beauty of the effect.
