There and then, where the acne cream goes (9)

'there' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'then where the acne cream goes' is the wordplay.
I cannot really see how this works, but
an anagram of 'then' is 'nthe' which is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

'and' is the link.

Can you help me to learn more?
