You have 2 basic options when it comes to permanent eyeliner. There is the lash line eyeliner or full eyeliner. Lash line eyeliner is a thin line 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 and just a little liner. Perfect to enhance your natural beauty.
With full eyeliner, it looks like you have obvious thick liner on. 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 full eyeliner you can decide whether or not you want a wing.
With both procedures you can also choose if you want just the top eyelid done or top and bottom.
