Chapped Lips + Vertical Labret= ?

I am usually the one answering the piercing questions, but here's a question for you all:

I had a vertical labret for a few months before I lost it due to jewelry falling out at night, but one problem I always, always had was that my lips were super chapped. As in, large pieces of skin could be peeled off my lip every few days.

Now, I want it redone, and unfortunately I work and go to school for most of the day, so constant re-hydration is not a viable option for me. I would like someone to tell me the best kind of lip solution safe for a fresh piercing. No, things like chapstick aren't effective, and gooey lipgloss or vaseline won't be good for the piercing. I need something natural, strong, and safe. Homemade remedies are fine, but if you do could you include a little more info than just the recipe?

For those who don't know, this is the vertical labret:
