Semi-permanent makeup is not a tattoo. So as the skin gets regenerated there will be exfoliation and the pigment will be faded away. The average maintenance period is normally 2~3 years. However if the semi-permanent makeup area is being touched or contacted a lot, it might fade away quickly. (e.g. sweating exercise, facial scrub or massage, sauna, whitening agents, etc.) Also the skin condition might affect the durability like oily skin.
