skin softener (6)
I believe the answer is:
lotion
'skin softener' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lotion that I've seen before include "Medicinal or cosmetic liquid preparation" , "Medicinal or healing liquid" , "Medicinal wash" , "Thick liquid for skin" , "Balm" .)
