Picosecond Laser For Removal of Solar Lentigines in Darker Skin Types

Picosecond Laser Effective for Solar Lentigines

A novel dual-wavelength, dual-pulse duration laser was evaluated for use on solar lentigines in 20 Asian patients with results showing 90 percent of patients achieved moderate to significant improvement. The study device was a dual‐wavelength, dual‐pulse width Nd:YAG laser that allowed for treatment with a 532nm or 1,064 nm wavelength in a 750 picosecond pulse duration. The treating physicians used the 532nm wavelength as its effect would be confined more superficially, which is ideal for the treatment of lengitines, and because it has greater melanin absorption than 1,064nm.

The PICOCARE from Wontech is a picosecond Nd:YAG laser featuring two wavelengths—532nm and 1064nm—for tattoo removal and the treatment of melasma and pigmented lesions. The shorter pulse duration minimizes damage to surrounding tissues while breaking ink particles into smaller pieces for more effective removal. The compact device offers real-time energy feedback, energy output of 600mJ, and 450ps and 750ps pulse durations. Contact: christopher@wtlaser, www.wtlaser.com.

Skin Histology Offers Insight into Picosecond Alexandrite Laser Mechanism of Action

Emil A. Tanghetti MD, expanded on his 2014 in vivo and ex vivo pilot study of the picosecond alexandrite laser to investigate how different energy settings affect the skin. He used a confocal microscope followed by biopsies to describe changes seen in the skin following in vivo treatment with a 755nm picosecond alexandrite laser with a fractional optic handpiece. Treatment was delivered at three different energy settings.
