Buy Art-Tattoo Galway vouchers for deals on Laser Tattoo Removal. What does laser tattoo removal involve? Lasers are used to fade unwanted tattoos, breaking down colours by reacting with ink pigments. Additional sessions may be needed depending on the size and colour of the tattoo in question, with bright colours and UV inks requiring more attention than darker ones. How can people prepare? Clients should shave the area beforehand and, if possible, apply a topical anaesthetic. After each session, aftercare includes applying an ice compress to the skin, and avoiding the sun and tanning beds.
