NATUREL permanent makeup will remain on the skin forever, like a tattoo. The only thing that can happen to the pigment is fading in the sun, like any paint or painted surface in the sun. That is, it will become the color of your skin and it will seem that nothing is left. Therefore, if you want to prolong the effect of NATUREL, then protect it from the sun every day, even on a rainy or cloudy day, with sunscreen with an SPF filter. Yes, one procedure can last a lifetime.
