The main indication for use of a picosecond laser is tattoo removal . Depending on the wavelength, they 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.
A picosecond laser selectively destroys the target pigment without damaging healthy, normal tissue. This allows rapid clearing of the abnormal pigmentation with minimal collateral damage to surrounding tissue.
Picosecond lasers used for tattoo removal require fewer treatments, cause fewer side effects, and result in reduced post-procedural downtime compared to nanosecond Q-switched lasers. They can clear some tattoos that are refractory to other forms of laser therapy and there is a reduced risk of causing scarring and hypopigmentation.
The use of picosecond laser 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 factlitate tissue remodelling and are used to treat acne scarring, photoageing and rhytides(wrinkle).
