maybe u can try out yr friend's BB lipstick. If it still doesn't help, maybe you can try:

1. use lipliner and a very moisturising lipgloss.

2. a lipstick that is half lip balm and half lipstick. have you u heard of the latest one from revlon?

3. tinted lip balm or maybe give yr lips some treatment. heard that you can use extra virgin olive oil to soften and condition your lips.
