Is Semi-permanent make-up really semi-permanent?

SPMU procedures are considered both permanent and semi-permanent. Permanent, because the pigment components will always be in the skin, although not visible to the eye. Semi-permanent, as the colour will fade, and therefore periodical visits are needed to refresh the colour. Factors that contribute to colour fading are: age, exposure to the sun, health, certain medications and the use of facial products containing exfoliation properties.
