Star from The Mask and Cream offering protection (9)
I believe the answer is:
sunscreen
'cream offering protection' is the definition.
'star from the mask' is the wordplay.
'star' becomes 'sun' (Sun is an example).
'from' is a charade indicator (letters next to each other).
'the mask' becomes 'screen' (I've seen this before**).
'sun'+'screen'='SUNSCREEN'
'and' acts as a link.
(Other definitions for sunscreen that I've seen before include "recommended for summer picnic?" , "summer holiday preparation" , "protection from harsh light" , "UV blocker" , "Tanning protection" .)
