Aquaphor Baby Healing Ointment
A barrier ointment thin enough to use at every single change, which is what actually prevents rash. Also fixes cracked knuckles, dry cheeks and your own hands.

When a wet diaper is going to sit for a while, like overnight, this paste is built for that stretch. It's formulated with maximum strength 40% Zinc Oxide to treat rash and creates a barrier so irritated skin stays protected through longer exposure.
