Follow up to Other Question-- Toddler Drooling Rash -- Worse -- Use Densitin???

Hi All. You came up with great ideas to help my son's drooling rash. We do have an appt with a pediatric dermatologist, but in 2 weeks!!!! So...As I have tried Aquaphor and Vaseline, and it does not work, has anyone tried using Densitin or Weleda Diaper cream on the face??? Do they make the toddler's sensitive skin more sensitive to the sun??? Thank you as usual for your good advice.
