Confusing Bill, Pam's ointment (3,4)
I believe the answer is:
lip balm
'ointment' is the definition.
(lip balm is a kind of ointment)
'confusing bill pam's' is the wordplay.
'confusing' is an anagram indicator.
'bill'+'pam'='billpam'
'billpam' with letters rearranged gives 'LIP BALM'.
(Other definitions for lip balm that I've seen before include "Salve used around the mouth" , "Ointment for the kisser" , "Item for chapped facial features?" , "Salve applied round the mouth" .)
