He looks very healthy.
Hopefully he will soak and shed tonight ?
I would give it it another night?
See what others think.
A rub would not be white like this.
I worry about putting neosporin that close to his eyes?

You could email Dr Frye,
I'm thinking he would suggest Silversulfadiazene for a nose rub? Don't know?
You really should the have it anyway. He could expedite the shipping.
The silversulfadiazene is much thinner ... it is used when there is a need for a topical antibiotic and/or anti-fungal
It works more quickly as well.
