What is Picosecond Laser?

Picosecond laser refers to a category of laser technology that delivers laser pulses at an incredibly short duration, measured in picoseconds (one trillionth of a second). This distinguishes it from traditional nanosecond lasers, which emit pulses over a longer period. The primary advantage of the picosecond laser is its ability to deliver high-energy pulses in such a brief time that it minimizes thermal damage to the surrounding tissues, thereby reducing the risk of side effects such as scarring and hyperpigmentation.

The core principle of picosecond laser technology is the photoacoustic effect, which involves the generation of shockwaves within the target pigment cells. These shockwaves effectively shatter the pigment into tiny fragments, and the body’s lymphatic system then naturally eliminates them. Unlike traditional laser technologies that use the photothermal effect, the photoacoustic approach ensures minimal heat damage to the surrounding skin tissues, making picosecond lasers a safer and more precise option for skin treatments.

Treatment Area of Niansheng picosecond laser machine

1. Tattoo Removal

Picosecond lasers, however, excel in breaking down tattoo pigments into smaller particles more efficiently

2. Treatment of Hyperpigmentation

Hyperpigmentation, including conditions like melasma, age spots, and post-inflammatory hyperpigmentation

3. Skin Rejuvenation and Resurfacing

By stimulating collagen production and promoting tissue remodeling, picosecond lasers help improve the overall texture and appearance of the skin.
