This is one of those products that I probably have one of in each room of the house. I have full lips, but they aren't perfect , often it's like the edges lose definition making my mouth look smaller. Yet when I try to fill them in with a lipliner it looks like too much, like I've been overdrawing my lips. This is the perfect lip liner for me, because it creates natural definition. It has this slight greyish brown undertone that ladies with genetically gifted large lips (think Scarlett Johansson, Angelina Jolie) have around the edges of their mouth.
