Lotion seems silly to Tinmen (8)
I believe the answer is:
ointment
'lotion' is the definition.
(I've seen this before)
'silly to tinmen' is the wordplay.
'silly' is an anagram indicator.
'to'+'tinmen'='totinmen'
'totinmen' with letters rearranged gives 'OINTMENT'.
'seems' is the link.
(Other definitions for ointment that I've seen before include "Soothing cream 98)" , "Medicinal rub" , "Balm, healing salve" , "Soothing unguent" , "Lotion" .)
