This will last up to 8 days IF you don't wash your face. Otherwise, expect to reapply at least daily. I didn't bother after the first day. The color is more "baby poop yellow" than light brown. But the concept is good, and if I could get a color that matches my light brown eyebrows, I might try it again.
