For some reason this waterproof eye liner doesn’t stay on long for me. I’m assuming my eye cream is the culprit. Everything else I’ve purchased is fabulous!!

I love the color, but come on I used it maybe 5 x and there is nothing left of it. There is no way to turn it up or get more out of this? Once you sharpen it, it is gone. Not for this price, never again .
