Choose lipstick perhaps with care, to cover broken nose (4,2,4,4)
I believe the answer is:
make up ones mind
'choose lipstick perhaps' is the definition.
I can't judge whether this definition defines the answer.
'care to cover broken nose' is the wordplay.
'care' becomes 'mind' (I've seen this in another clue).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'cover' becomes 'makeup' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'broken' indicates an anagram.
'nose' with letters rearranged gives 'ones'.
'makeup'+'ones'='makeupones'
'mind' put after 'makeupones' is 'MAKE UP ONES MIND'.
'with' acts as a link.
Can you help me to learn more?
(Another definition for make up ones mind that I've seen is " Decide".)
