Beauty-cream additive (4)
I believe the answer is:
aloe
'beauty-cream additive' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aloe that I've seen before include "Bitter drug from a leaf juice" , ". . . . vera, soothing plant" , "Bitter fruit" , "Genus of bitter herbs" , "Succulent plant (4) 5532" .)
