eyeliner usage

Lately, my eyelids have been drooping, so I use eyeliner. Before, I used to apply eyeshadow over it, which took a long time and was very inconvenient because it kept smudging and I had to redraw it. However, since last year, I have been using this eyeliner, and it creates a clear eye look with just one or two strokes. I don't have to redraw it, so it saves a lot of time, and I am using this product very comfortably.
