Just as people come in all shapes and sizes, so do their lips. Some have thin lips, some have unbalanced lips (meaning one lip is thin while the other lip is not). As with other facial features, knowing how to use makeup can mean the difference between getting the look you want or not. Using it incorrectly can have unattractive consequences. There are just a few tips to know to get the perfect lip shape.

1. Thin lips
For those who want fuller-looking lips there's good news. There are several ways to make lips appear larger. Start with a lip pencil that's close to the lip color you'll be using. Draw slightly outside of your natural lip line following the shape of your lips. Set the lip liner in place using a powder and then fill in lips with a lipstick or lip stain. Using a lip gloss can also help make thin lips look fuller, but could displace or ruin lip liner.

Avoid dark colors; They make lips look thinner. Use a light or medium shade that flatters your natural coloring.

Plumping lip products
Plumping lip products can help create the look of fuller lips as well. Lip Fusion XL by Fusion Beauty and Physicians Formula Plump Potion Needle-Free Lip Plumping Cocktail Clear Potion 2704 are just two of the many products available. Results and prices vary widely among products.

Highlight the Cupid's Bow
Another way to create fuller-looking lips is by adding a highlight to the Cupid's Bow area of the lips. You can use a concealer or try a product like NYX's Wonder Pencil. Draw it on above the natural lip line directly on the Cupid's Bow. Blend it well. Follow with lip liner and lip color.

2. Full lips
Full lips are considered aesthetically perfect. That's great news if you're lucky enough to be born with full lips. But some women may prefer that their lips were thinner. To achieve this, choose a lip liner close to your natural lip color. Draw just inside the natural lip line, then fill in lips with the lip color of your choice. Avoid light colors that make lips look even fuller.

3. Uneven lips
If a top or bottom lip is full but the other lip is thin or medium, the lips are uneven. To correct this, follow the instructions above for the lip you want to correct. For example, if you want to correct a top lip that's too thin, use the corrective technique outlined under “thin lips” above. If the bottom lip is too full for your taste, try the technique under “full lips” above.

Setting your lip line with powder
Keep in mind that if you create a new lip line with your lip pencil, you should set it with powder to keep it in place. Be sure to touch up after eating or periodically during the day as lipstick wears off. You want to avoid having a lip liner with no lipstick, which looks unnatural and unattractive.

Whether you have thin lips, full lips, or unevenly balanced lips, a little makeup know-how can help. Using the techniques above, you can get luscious lips you want.
