Does permanent eyeliner fade over the years?”
From Lynn Duncan Permanent Cosmetics: Duncan explained that as the years go by, the permanent cosmetics will fade to a softer tone than the initial color. So, in three to five years, people may desire color enhancements to refresh their permanent cosmetics And from the less gimmicky wikipedia: The pigmentation of permanent makeup may fade over time, particularly under the effects of sunlight. It usually lasts for a decade or more before fading significantly. Touching up the makeup may be required to restore the original color. I myself have several black tattoos, the oldest is 7 years now and it hasn’t faded too much. But if it were eyeliner, I would be ready to touch it up about now.
