Results vary from person to person because skin type, diet, genetics and environmental factors can all contribute to how long the pigments will be retained. On average, it could be anything between one to five years before a new treatment is required, although refresher color boosts are recommended for maintenance during this time. Once the color starts to change you will know that you are ready for your refresher color touch-up. It is important to remember that permanent make-up is a “low” -not a “no” -maintenance treatment.
