A new long pulsed 940 nm diode laser used for hair removal in Asian skin types

Abstract

BACKGROUND: The theory of selective photothermolysis has led to the development of a variety of different hair removal laser systems.1,2 These lasers use follicular melanin as a target chromophore. At present the delivery of adequate fluences, optimizing wavelengths and pulse duration, and adequate epidermal cooling are the factors required to achieve effective hair removal. To further evaluate these factors a study was initiated to further investigate a new laser system.
