Okay so I'm picky about eyeliner... It isn't my fave but it HAS become part of my routine now. I use it in combination with Maybelline Eye Studio gel liner, but, I use this for my tightline and waterline.
I've been using various types of liquid liners for years. I was amazed by how much trouble I had with this one. The first time I tried this... SUCH A MESS! It was EVERYWHERE. I only use it between my lashes (tightline) and on my upper waterline. However, I've learned a neat trick... If I let a bit of this get on my actual lashes, let it dry for a few seconds (20,or so) , and then use an eyelash curler... It gives a crazy awesome curl that stays much longer than I've had before. Then, I Apply the gel liner wing to the upper lid, a couple coats of waterproof mascara (lash bloom) and MAGIC. Stays put all day even if you cry your eyes out!!
