Background: Telangiectases are cosmetically concerning for millions of individuals who develop them on the face as they mature. The causative factors are numerous. Lasers have recently become the focus for treating small facial telangiectases because of their ability to selectively target vessels.

Objective: The purpose of this study was to compare the efficacy of four different frequency-doubled neodymium:yttrium-aluminum-garnet (FD Nd:YAG) laser (532 nm) systems for the treatment of facial arteriolar telangiectases.

Methods: Forty adult subjects with Fitzpatrick skin phenotypes I and II were randomly assigned to four treatment groups. Each group, consisting of 10 subjects, had telangiectases less than 1000 microm in diameter treated with one of four different FD Nd:YAG laser systems with a wavelength of 532 nm. Patients were treated once and clinical improvement and potential adve...
