Translation: Self-Conscious
If I am to translate:

The cameras made her self-conscious about her weight:

拍照让他在意起自己的体重

Don't mention his acne, he's really self-conscious about it.

别提起他的暗疮，他很介意。

PS: I suppose you were right, we might not really have a definite word/phrase for its translation, but i'd say it is very close to 介意/在意
