Hi Marissa!

I like Curel lotion the best---it soaks in quickly and so doesn't transfer to
the clay, but even if lotion DOES get in there, most don't seem to interact.
The other thing I HIGHLY recommend is Burts Bees Cuticle lemon cream; my
cuticles and fingernails don't get dry and leave marks in the clay.
