Pigmentation removal with pico laser

1.What is a picosecond laser?
A picosecond laser is a laser device that uses very short pulse durations to target endogenous pigmentation and exogenous ink particles (tattoos). The medium varies accordingly to the wavelength being used, whether the neodymium-doped yttrium aluminium garnet (Nd:YAG) crystal (532 nm or 1064 nm), or the Alexandrite crystal (755 nm).



2.What are the indications for a picosecond laser?
The main indication for the use of a picosecond laser is tattoo removal. Depending on their wavelength, picosecond lasers are particularly useful for clearing blue and green pigments, which are difficult to eliminate using other lasers, and tattoos that are refractory to treatment with the traditional Q-switched lasers.

The use of picosecond lasers has also been reported for treatment of melasma, naevus of Ota, naevus of Ito, minocycline-induced pigmentation, and solar lentigines

Some picosecond lasers have fractionated hand pieces that facilitate tissue remodelling and are used to treat acne scarring, photoageing, and rhytides (wrinkles)
