Loud 60s band hoards top-notch moisturiser perhaps (4,5)
I believe the answer is:
face cream
'moisturiser perhaps' is the definition.
'loud 60s band hoards top-notch' is the wordplay.
'loud' becomes 'f' (A musical term).
'60s band' becomes 'cream'.
'hoards' is an insertion indicator (hoard can mean to contain).
'top-notch' becomes 'ace'.
'f'+'cream'='fcream'
'fcream' enclosing 'ace' is 'FACE-CREAM'.
(Other definitions for face cream that I've seen before include "Skin cosmetic" , "Mug gets this application" , "Mecca fare (anag.)" , "Cosmetic designed to improve complexion" .)
