Totally forgot she was in SoCal and probably has a tan which alleviates a LOT of the need for makeup.
I know there are a lot of Bare Minerals fans on here, but my experience with it has been that it does take time to learn to apply correctly and some women using it NEVER get it. If you're tan, and wary of makeup as it is, just using blotting sheets is probably easier.
As far as lip balm, look into the Burts Bees or
Terra Tints. BB is everywhere and you can find Terra Tints at Whole Foods or similar type stores. You'll be out in the sun a lot and talking a lot and you need something to keep your lips moist. This adds a hint of color and is practically impossible to screw up.
