Study of Picosecond and Nanosecond Q-switched Lasers for Tattoo Removal

Randomized, Split-tattoo Study Comparing Safety and Efficacy of Picosecond and Nanosecond Q-switched Nd:YAG Lasers for Tattoo Removal

The purpose of this study is to compare the investigational medical grade laser device to a marketed medical grade laser device for effectiveness in lightening or clearing unwanted tattoos. This study will also compare any side effects from treatment with the devices.

This is a two center study to evaluate the Cutera RF system. Subjects will be treated on the abdomen and / or flanks areas and / or saddle bag (upper lateral thigh, lateral hip and lower buttocks).

The objective of this study is to evaluate the thermal and histological changes observed in the subcutaneous tissue following RF exposure.
