你的素颜已经看不出了纯真
[nĭ de sù yán yĭ jīng kàn bù chū le chún zhēn]
Your unadorned face can no longer show simplicity and purity. This implies that the originality and naturalness, both in personality and appearance have been overshadowed, hinting at artificialness and losing initial innocence or straightforward quality.
