A benefit, after shave possibly for young person (10)
I believe the answer is:
adolescent
'young person' is the definition.
(I've seen this before)
'a benefit after shave possibly' is the wordplay.
'benefit' becomes 'dole' (I've seen this before).
'after' says to put letters next to each other.
'shave possibly' becomes 'scent' (I can't justify this - if you can you should believe this answer much more).
'a'+'dole'+'scent'='ADOLESCENT'
'for' is the link.
Can you help me to learn more?
(Other definitions for adolescent that I've seen before include "Teenager" , "Teenage" , "juvenile" , "Young person" , "One growing" .)
