I want to plump up my very thin lips. What's the trick to making them look fuller?
Use a nude lip pencil (try Kevyn Aucoin The Flesh Tone Lip Pencil) and gently use the pinky of your opposite hand to lift the outer edge of your lip line while sketching the pencil slightly above your natural lip line. Begin from the outer corner working in and avoid drawing two peaks at the bow, instead round out the top. Lifting the edge of the lip will naturally create a fuller lip over looking drawn in.
