Ten Eyeliner Mistakes to Avoid
10. You’re smudging your liner too low. This can make you look like you have a black eye.
The fix: Line your eye as close to your lash line as possible, and then use a smudger brush, which is tightly packed and skinny enough that it won’t blend the liner below where it should be. Also, it should be diffused as you blend it out rather than so intense (think: smoky, not solid black), for a sultrier look.
