In respect to this, can you tattoo with eyeliner?
Although it's called permanent eyeliner, eyeliner tattoos are actually semi-permanent, which means if you want it to last forever, you'll have to get it touched up as it fades.
Also Know, do stick n poke tattoos last forever? Nope. Odds are your stick and poke won't grow old with you. They fade faster than professional tattoos, especially on areas that you clean often like your fingers.
Also, is Sharpie safe for stick and poke?
Although sharpie ink is non toxic, I would never use that to tattoo on myself or anyone else. If you're desperate for a tattoo it's best to wait, save up money, do your research and go to a professional tattoo artist that can work on you safely, cleanly, with all of the precautions that come with being a professional.
Can you use liquid eyeliner as tattoo ink?
You can get tattooed by anything and any ink (just look how they do it in prison or in third world countries). Now because eyeliner ink may not be as dense or thick as regular tattoo ink than it may not be as visible or when it heals or will appear how it's supposed to depending on the size of the tattoo.
