January 30, 2017 updated by: Cutera Inc.
A Prospective Multi-Center Study of a Novel Dual-Wavelength, Dual-Pulse Duration Laser for the Treatment of Melasma and Lentigines in Asian Skin
The purpose of this investigation is to evaluate safety and efficacy of the Cutera enlighten dual-pulse duration, dual-wavelength 532nm KTP/1064nm Nd:YAG laser for the treatment of melasma and lentigines on the face in Asian skin.
Study Overview
Detailed Description
This is a multi-center prospective, 2 cohort study in 80 male or female subjects of Asian-descent, who desire laser treatment for moderate to severe melasma (all types) or lentigines (all types) located on the face.
Forty subjects will be enrolled in cohort 1 and randomized to either treatment or control arm.
Forty subjects will be enrolled for treatment of facial lentigines in cohort 2.
