Look into new liquid preparation (6)
I believe the answer is:
'liquid preparation' is the definition.
'lotion' can be an answer for 'preparation' (I have seen 'Medicinal preparation ' mean 'lotion' so perhaps 'preparation' could also mean 'lotion'). I'm unsure of the 'liquid' bit.
'look into new' is the wordplay.
'look' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'new' indicates an anagram.
'into' anagrammed gives 'tion'.
Can you help me to learn more?
(Other definitions for lotion that I've seen before include "Balm" , "Soothing or antiseptic preparation" , "Preparation that's applied to the skin" , "Medicinal or cosmetic liquid preparation" , "Soothing liquid preparation" .)
