So there was one more thing I wanted to say about lipliners, and I held back this morning because I was afraid it might sound crazy (the comments posted thus far have made me bold).
I have found another — rather unexpected — use for lipliners. I went to a costume party recently, and needed a matte coral lip. I had nothing in my makeup bag fitting that description — except an Estee Lauder gift-with-purchase lip pencil (Coral Blaze, if you’re curious. They don’t even make it anymore). It looked great for the party and opened up a whole new world to me: liner as lip color.
What I’ve learned from subsequent experimentation: If you’re going to try this trick, apply the liner to dry, bare lips — ideally, blot afterwards. Do not prime. Do not put chapstick on top, as this will most definitely result in lipliner on your teeth. This might not be the best choice for people with dry lips, but it’s one more makeup option to add to your arsenal.
