take a look at the site here Permanent Eyeliner is a cosmetic tattoo. Similar to a body tattoo, a machine with a sterile needle is used to deposit ink into the skin along the eyelid. The purpose of this is to enhance your eyes and simplify your beauty routine! It is one of our favourite treatments here at The Perfect Feather! Permanent eyeliner is very versatile; there is a style to suit everyone, from dainty and subtle to dark and dramatic.
