I hafta agree with another poster. Creamy lipsticks and glosses are awesome. They make the lip look so moisturized and juicy. Since yr 15 I think you can get away with a nude lipstick or a tendertone/HIP jelly thingie. Or any creamy lipgloss. When yr lips look nice and juicy you'll see that and appreciate the full/thick-ness of them. But the creamy consistency, I think will make you most comfortable.
