Bright fire engine reds can point up problems. If you have a problem with lipstick blurring, try outlining the lip with a lip liner pencil, then filling in with colour. Powdering the first coat of lipstick then applying a second coat, will help it to last longer. Most men have thin lips and need to make them appear fuller. Don't hesitate to paint your lips slightly outside your upper and lower lip line.
Women have the same problem.
But be careful to not overdo it. If your new mouth seems a bit extreme, try increasing the size slowly, a bit at a time over a period of a few weeks, so you can get used to it. Using a softer red will help to keep your lips from looking too showgirl. Its fun to mix your own colour by using several different lipsticks on top of each other. Try putting a neutral light pink shade on top of a deeper red.
