Think your lips are too small or too thin? The key is to use lip liner and a high-shine gloss to make them appear fuller. Start with a pencil in a natural color. Using short strokes, line the edge of your lips. After you have outlined your mouth, follow up with a shiny gloss or sheer lipstick in a color close to your lip shade. Avoid dark lipsticks because they will only emphasize how small your lips are. A lip gloss or sheer lipstick will reflect the light and give the illusion of larger, fuller lips -- dot some gloss in the center of your top lip.

If you would like to make your full lips appear smaller, use matte lipstick. Gloss reflects light, making lips appear larger (see above), but a matte finish will de-emphasize fullness. Use subtle colors like soft pinks, nudes or peaches. It is never necessary to use a lip liner on full lips.
