Your lips can thin with age. But there are ways to make them look full again.
Choosing the right color for thinning lips matters. Again, avoid strong colors like red. Those can make lips appear even thinner. Peach and beige colors, lip glosses, and tawny liners make them appear fuller and more defined.
Liners can help complete the illusion of fuller lips. Draw just on the outside of the lips and fill in with color, but don't to make them too rigid. "Most people use the pencil to outline the lips first," Lowe says. "This creates too much definition in the lining of the lip. Instead, use color first and then line the lip. It gives it a softer line that is still defined."
If you have feathery lines around your lips, use matte lipsticks and lip liners to keep lipstick from bleeding into them. Kidd recommends mixing a good lip balm with your favorite lip color for a glossier, more subtle look.
