I first tried Bare Escentuals with a starter kit that came with Buxom Lip Gloss in Ginger.  I absolutely love the color, and while there is a tingling sensation, I haven't noticed my lips looking any larger.  Granted, I wasn't expecting a huge difference, but thought there would be some.  I have since bought several more Buxom lip glosses because I love how they are shiny without being sticky.  I also love the lasting colors.
