To keep your lipstick from bleeding, trace your regular concealer around the outer edge of your mouth, then press it into the skin with your finger to blend.
Next, tap a thin layer of the concealer over your entire mouth. (If your lips are dry, dab on a bit of waxy balm first and wait a minute for it to be absorbed.) This helps your lipstick adhere so it won't fade or run.
When in doubt, a medium coral shade flatters all skin tones. Swipe it on, following the natural shape of your lips. To make them appear fuller, you can go a smidge outside your lip line, but no more!
Blotting removes the excess moisture that causes feathering. Fold a tissue in half, then lightly pat it along your entire mouth, including the lip line. Add a second coat of color, press your lips together to set, and you're done.
