Pico laser, also known as "super picosecond," is a high-tech laser technology used to improve skin quality, skin pigmentation, and acne scars, and promote the growth of skin collagen and renewal. The Pico laser has a shorter pulse time and can more precisely target the skin, reducing damage and stimulation to surrounding tissues. In addition, the Pico laser can also be used for tattoo and tattoo removal. The advantages of the Pico laser are safety, non-invasive, painless, short recovery time, and apparent effects, making it an increasingly popular cosmetic treatment.
