It's called Lipstick cuz' it stays on your Lips, It's not Lip glue Silly XD And when toi use Lipstick, Your NOT sopose to put it on the place where both Lips tuoch, And it won't stick there as well cuz' theres mouth water on that place, Whenever Lipstick touches water it turns into only Color, The Sticky-ness goes away, Well that's about it, Any other Questions?
the reason why toi can still déplacer your lips when toi have lip stick on is because it's not sticky and it is made for toi to be able to mave your lips.
