On average, it takes 2-6 years for permanent eyebrows to fade.
This mainly depends on application method and pigment color. The hand-held application method is much more delicate and thus, will fade faster. If the pigment is a light color, it will fade faster. This is due to our skin’s self exfoliating mechanism that occurs every 28 to 45 days.
To preserve and prolong the appearance of permanent eyebrows, it is important to use gentle cleanser, to not over-exfoliate, and to use sunscreen thoroughly.
