Review (4/5): Treat this like tattooing! Be careful with application.
Awesome product but DO NOT GET ANYWHERE THAT YOU DON'T WANT COLOR. I originally thought it would be similar to dying brows with hair color but this color dyes your skin permanently and it takes days to fade. I was not careful with where I was applying since I thought it would only dye my hair and not my skin. Had to use alcohol to remove the dye from my skin and it caused a lot of irritation. It's an awesome product otherwise, just make sure your lines are perfect and you only apply this where you want color!
