An Nd:YAG laser is used with the aim of tackling the growth of fungi on toenails and fingernails. Results vary and additional sessions may be required. What happens at the session? First, a consultation is held to discuss the procedure and address any questions or concerns. The treatment can then be performed on up to ten toenails or fingernails, or a mix of the two up to a total of ten. Clients must trim their nails before the appointment to ensure the lasers have optimal effect. Expressmile specialises in high-tech cosmetic services at a clinic on Bolton Street in Dublin 1. The clinic uses equipment such as Q-switched Nd:YAG lasers to perform treatments like laser tattoo removal, IPL hair removal and fungal nail treatments, all available until 7pm six days a week.
