Serenely I adjust the cosmetics (9)

I believe the answer is:

eyeliners

'the cosmetics' is the definition.
(I've seen this before)

'serenely i adjust' is the wordplay.
'adjust' is an anagram indicator.
'serenely'+'i'='serenelyi'
'serenelyi' with letters rearranged gives 'EYELINERS'.

(Other definitions for eyeliners that I've seen before include "Kohl" , "cosmetics" .)

I've seen this clue in The Sydney Morning Herald.
