Picosecond Laser Treatment for Tattoos and Benign Cutaneous Pigmented Lesions

Abstract

A series of picosecond lasers, having shorter pulse durations within less than 1 ns, are newly being used in the field of dermatologic laser surgery. Stress relaxation theory is considered to be involved in the actual setting, enabling higher efficiency in tattoo removal using picosecond lasers compared to conventional nanosecond Q-switched lasers. Furthermore, picosecond lasers are increasingly being anticipated to be used for aesthetic skin treatment. However, evidence for this aesthetic effect remains scarce thus far. Therefore, future studies on development of the technique are warranted.
