Nd:YAG Technology for Laser Hair Removal: What's New?

Abstract

BackgroundSince its inception, the Neodymium‐doped yttrium aluminum garnet (Nd:YAG) 1064‐nm laser has been widely used for the treatment of hair removal. Selective photothermolysis forms the basis of its function. Without harming the skin, the laser damages the hair follicle, offering safety and potentially positive outcomes. Many years after its debut, newly developed Nd:YAG laser technology and additional indicators have been found.MethodsThe quality of the evidence was evaluated using PubMed and Google Scholar searches. A selection of articles published between 2019 and 2024 underwent a retrospective review.ResultsUpdated technology, including the “in‐motion” technique, submillisecond pulse, and the combination of alexandrite and Nd:YAG lasers, achieves effective hair reduction with a higher safety profile. Other effects of the Nd:YAG laser on sweat glands, its bactericidal effects, and its long‐term effects on laser providers are discussed in this literature.ConclusionWith minimal short‐ and long‐term side effects, the latest technology and techniques of Nd:YAG laser treatment at a wavelength of 1064 nm have been shown to be beneficial and promising for hair removal.
