The Removal of Eyebrow Tattoos by the Q-switched Alexandrite Laser / 대한피부과학회지

ABSTRACT

BACKGROUND: Women sometimes have eyebrows tattooed for cosmetic purpose. But until recently, the removal of tattoos has been difficult. Several laser techniques have been proposed for the removal of tattoos. The lasers that have been used most successfully are the Q-switched systems because of their ability to target tattoo pigment selectively with minimal risk of adverse tissue response. OBJECTIVE: The objective of this study was to determine the clinical effectiveness of the newest Q-switched system, the alexandrite laser, in removing both eyebrow tattoos and to observe side effects such as scarring or permanent pigmentary changes. METHODS: Forty seven patients with both eyebrows tattooed were treated with the Q-switched alexandrite laser (755 nm, 100 ns) at eight week intervals and clinically evaluated.
