Eyeliner is a Permanent Cosmetic makeup also called Tattooed Eyeliner. Micro-droplets of colored pigments are inserted between your lashes and under the skin with a machine. This process may be done over several passes, or it may even be done over several appointments to monitor the color absorption. A numbing cream will be applied to reduce discomfort. The tattoo eyeliner color and shape is customized to your preference. The suggestion is to keep permanent eyeliner as simple and natural as possible.
