The most commonly used devices include Intense Pulse Light (IPL), the alexandrite, Nd:YAG, and diode lasers1, all of which have proven safe and effective for removing unwanted hair. Recently a new near-infrared diode laser system (VectusTM, Palomar Medical Technologies, Burlington, MA) has been introduced with features that provide fast, safe and effective hair removal. Unique design features of the VectusTM system include an optimum wavelength for hair removal (800 nm), high peak power (3000 W), a uniform beam profile, a smooth pulse shape and photon recycling, all of which provide greater energy delivery to the hair follciles2. A clinical trial to validate the system’s performance and design features was completed to demonstrate long-term efficacy.

Vessels in leg telangiectasias are larger than those in PWS. Longer pulsewidths and wavelengths may improve clearance of these larger vessels. Twenty patients were treated using PDL at 595 nm and 1.5 msec. Vessel diameters ranging from 0.635 to 1.067 mm were treated using energy densities of 15 and 18 J/cm2, and a 2 x 7 mm elliptical spot. Telangiectasia clearance and complications were scored at 6-weeks and 5-months following the single treatment. Results demonstrated > 50% clearance by 6 weeks in 11/26 (42.3%) patients using 15 J/cm2, and 6/13 (45.2%) using 18 J/cm2. By 5 months > 50% clearance was noted in 18/34 (53.0%) using 15 J/cm2, and 11/17 (64.7%) using 18 J/cm2. Complications were minor and infrequent. The long-pulse PDL may have a role in treating leg telangiectasias.
