I absolutely love my Kosas mini wet lip oil I got from the Sephora box just before it stopped. As you can see from the pink applicator I like to slick it on top of my lipsticks to give a bit of shine. It's my fave lip oil, stays on quite a while and just adds an extra something something (it's plumping too!) There's something beautiful about the way it catches the light and I sometimes really build it up before I take a pic for an unreal glossy shine
P.s. can't tag the kosas wet lip oil on the post
