What is the difference between Pico laser and toning laser?

Traditional laser toning delivers energy in nanoseconds, while Pico laser delivers energy in picoseconds, which is about 1000 times faster. Because of the faster delivery speed, it can break down pigment particles more finely and reduce damage to surrounding tissues, making it relatively advantageous for stubborn pigmentation. However, which method is more suitable can depend on the depth and type of the pigment.
