Long-lasting permanent cosmetics pigments are created to closely resemble the colour of conventional makeup. A permanent eyeliner tattoo's colour may, however, fade or alter over time owing to a multitude of circumstances, including sun exposure, skin type, and the calibre of the pigment used, much like the colour of any tattoo.
According to
Permanent Makeup California, if the pigment used contains copper, permanent eyeliner may turn blue. Some tattoo inks frequently contain copper, which over time may cause the tattoo to turn blue or green. A permanent eyeliner tattoo's colour may also alter as a result of fading or the ageing process.
