Hands down, this is the best liner I have ever tried. I have always struggled with eye liners due to the skin around my eyes changing with age. Over the years, I have purchased tons of eyeliners from drug stores to high end department stores and none of them worked for me until this one. Not only does it go on smooth but it also stays put! I was skeptical at first but after I had it on for over 12 hours I knew this was the one! It goes on easy, does not smudge once set and stays there all day long. Easy to correct and smudge with my finger if I want to. Well done!
