How do you line your waterline without discomfort?
This is where my teenage years of awful makeup come in handy. The first makeup I wore regularly was very stereotypically Desi: black-black smudgy eyeliner in my bottom waterline. The evidence is in my passport photo, in which I look, well, you can see for yourself how rock-wannabe I appeared below the jump.
The results may have looked terrible, but in the long term, the habituation means that I can poke a pencil near my lower eyeball without flinching or blinking very much.
Aside from habituation, there are three other factors to consider when it comes to waterlining.
