I have difficulty with keeping eyeliner on my waterline no matter what kind I use. However, CARGO's kohl pencil is very black and does pretty well, as do Urban Decay's 24/7 eyeliners. MAC Fluidlines and Stila Smudgepots are probably my favorite though--I gently pat the product onto the waterline with an eyeliner brush.

I always use a pencil liner and/or fluid lliner on the bottom waterline as well as right under the lash line. To make it last longer, I then take a small rounded brush and apply a matching (or a color in the same family) and apply an eye shadow. This will also give that sultry look, especially with a deep brown. This really helps me. Always apply a primer and it will last all day.

The creamier the pencil or my choice MAC fliud line in dip down, the better the shadow will stick.

Best of luck!

First, don't line the inside of your eye.  It can cause bacteria to get into your eyes, and it looks too harsh.  Use a kohl eye pencil directly under your eye.  Then take a cosmetic wedge or Q-tip and smudge it gently.  Then take an angled brush and lightly sweep the color of your eyeliner (which I assume is black or brown) over the eyeliner with an eyeshadow.  Don't create raccoon eyes.  All of this is small applications.  Don't make wide lines and smudges.  I guarantee your liner will stay on.  The secret is the smudging and powder eyeshadow over the liner.  It makes a very nice smokey eye, which is all the rage right now.  I am a cosmetology student and I completed the L'Oreal Academy plus I am an Allstar with Total Beauty.

Good luck.  It works and you will be very happy.
