Reason to moisturise my skin - finally getting into habit (7)
I believe the answer is:
dryness
'reason to moisturise' is the definition.
I can't tell whether this definition defines the answer.
'my skin finally getting into habit' is the wordplay.
'finally' indicates one should take the final letters.
'getting into' indicates putting letters inside.
'habit' becomes 'dress' (I've seen this before).
The last letters of 'my skin' are 'yn'.
'yn' going within 'dress' is 'DRYNESS'.
Can you help me to learn more?
(Other definitions for dryness that I've seen before include "Parched quality" , "Characteristic of some wines" , "producing thirst" , "Lack of moisture" , "Matter-of-fact quality (of humour)" .)
