I use this on it's side to tight line my upper lash line. I also use the side of the tip if I want to line just above the lash line as well. The only time I use the tip is for the inner corners of my eyes. This has kept the tip fairly pointy. As I wear the product down, I think I'll just eventually use a brush to apply. I don't need to apply any product on my lower water line because it smudges there after a few blinks.
See the reviews - this stuff does not deposit any worthwhile color on the waterline.
