It mostly depends on three things: The color that was chosen, the quality of your skin and on how well you follow the aftercare recommendations. Usually, procedures done with blue and black pigments, which are only used for eyeliners, have an average duration of ten years, without any need for a touch-up.
Procedures done in brownish tones (eyebrows) and red tones (lips) have a shorter duration, usually between two to five years, in very good shape. It is important to note that patients have different skin types, which highly determines the longevity of the make-up. This makes establishing a standard duration a very hard task.
In general, the wider the lines and the darker the color, the longer it lasts. At the same time, the thinner the line and the lighter the color, the less it will last. Nevertheless, it must be noted that sometimes it is more aesthetically pleasing to chose thinner lines and lighter colors even if it does last less (sometimes even a year or less). This is a decision that the client must state on the consent form before the procedure begins.
