The new 730-nm picosecond laser demonstrates strong efficacy and safety in darker skin types for treatment of endogenous pigmentary disorders, according to a recent case study.
A case report published The American Society for Laser Medicine and Surgery shows the new 730-nm picosecond laser to have strong efficacy and safety in treating endogenous pigmentary disorders on darker skin types.
Typically, picosecond lasers have been used for tattoo removal but are gaining traction as a novel treatment for pigmentary disorders, a market which has previously been dominated by quality-switched nanosecond lasers. The 730-nm picosecond laser was specifically designed to target melanocytes and melanin.1
The study examines two Korean patients with III-IV Fitzpatrick skin types, as well as melasma, freckles and lentigines who were treated with 730‐nm Ti:Sapphire picosecond laser (Picoway, Syneron Candela Corp) with a pulse duration of 240 picoseconds.2
Both researchers saw significant pigmentary reduction and with one treatment session, which was well tolerated without topical anesthesia in both patients. In the 6-week follow-up, there were no observed post-inflammatory hyperpigmentation/repigmentation in either patient.1
“The new commercial 730 nm laser-pumped laser may be effective and safe in treating pigmentary disorders in darker-skinned patients,” says Sang Ju Lee, M.D., Ph.D., study investigator.
