Scold crumpling face mask (5)
I believe the answer is:
chide
'scold' is the definition.
(I know that scold can be written as chide)
'crumpling face mask' is the wordplay.
'face' says to take the initial letters.
'mask' becomes 'hide' (both can mean to conceal or cover up).
The first letter of 'crumpling' is 'c'.
'c'+'hide'='CHIDE'
(Other definitions for chide that I've seen before include "Tear off strip" , "Censure, berate" , "lecture" , "Censure angrily" , "Rebuke, scold" .)
