How to say "to look in the mirror"


What Japanese expression is equivalent to "to look in the mirror"? Is it as
simple as 鏡を見る or 鏡に見る?




For "look in the mirror" in the metaphorical sense "reflect on one's own
conduct" (with the implication that one will recognise one's wrongdoing and
resolve to behave better) how about 反省する (はんせいする) ?
