With the proper techniques you can have fuller-looking lips. Start by using a flesh-tone pencil to outline your lip line. This adds volume to thin lips. Then fill in your lips with the same flesh colored pencil. This helps your lipstick stay put all day long. Apply two coats of your favorite moisturizing lip stick. Dot your lower lip with clear lip gloss and press your lips together to blot the gloss. Gloss lips look plumper than lips with just lipstick applied.
