You have many options when it comes to permanent eyeliner. There is the lash line eyeliner or full eyeliner. Lash line eyeliner is to give the illusion that you have naturally fuller lashes. It's perfect for you when you go without make-up for the day but you still look like you have thicker lashes. You will look naturally beautiful.
With full eyeliner, you can stop dealing with the everyday hassle of trying to get your eyeliner perfect and even on BOTH sides. You literally wake up with make-up and can just go. It's perfect for convenience.
With both procedures you can also choose if you want just the top eyelid done or both.
