The woman looks into the mirror to see her reflection. But the mirror being objective - 'exact' and without 'preconception', 'unmisted by the love or dislike' shows her an image that she does not like. It shows her the flaws which have appeared on her face as she is agening. Though the mirror is being 'not cruel, only truthful' but truth itself is cruel and the woman turns away from it, presenting her back to that unbiased truth.
