This is still a tattoo where cosmetic pigment is being placed into your skin. Semi-permanent means it will fade over time, and that if you want to keep your lips looking vibrant, top up appointments will be needed to maintain this look. Semi-permanent DOES NOT mean it will 100% fade away. You may always be left with remnants of pigment under your skin even 10 years from now. Cosmetic tattoo pigments are made up of smaller molecules than traditional tattoo ink which means that they're able to break down naturally in your body over time. Cosmetic tattooing, when done correctly, is not implanted into the skin as deep as traditional body tattoos so will fade as your skin wears and regenerates.  Everyone's bodies will process the pigment differently, as well as your lifestyle choices affecting the longevity of the tattoo. This is still a tattoo, so before anyone tells you any differently, please bare in mind that whether or not you refresh your lip blush annually, you may still be left with a shadow or very faded lip line if you don’t wish to continue with annual top ups.
