Attention, artistes: The newest way to tint your lips is with the Lip Stain Pen by Bourjois ($15). Using this tool is very fun and French; it's like drawing on your lips. The pen, which comes in a charming Parisian-motif package, looks just like a magic marker with a rounded and soft felt tip. This not only ensures easy and fool proof application, but it also doesn't require a lip liner.
Since the colors are just slightly deeper than a flesh tone, the pen gives your lips a nice "just bitten" stain. You can layer the color for a sheer flush or apply multiple coats to reach your desired intensity. The formula lasts all day long and dries quickly on your lips. It is available in four colors: Rose Prefere (light pink), Framboise Bonheur (magenta), Peche Passion (bright tangerine), and Praline Dis-moi Oui (pink/brown).
