Meaning:

“容貌” means “appearance,” and “焦虑” means “anxiety.” Social appearance anxiety is a type of anxiety about one’s appearance and body shape. Sufferers are often young people who experience a fear of negative evaluation of their physical appearance. As the society as a whole focuses more on people’s appearance and rewards those with good looks in terms of employment and other aspects, more people begin to worry that they are not “good-looking enough” and turn to plastic surgery. A recent survey of some 2,000 Chinese university students found that 59 percent of the subjects have social appearance anxiety, with female students feeling more affected.

Example:

A: 我又胖了点儿，真不知道怎样才能更苗条。

Wǒ yòu pàng le diǎnr，zhēn bù zhīdào zěnyàng cáinéng gèng miáotiáo。

I have put on some more weight. There’s just no way to slim down.

B: 你的身材很标准，完全没有必要容貌焦虑。

Nǐ de shēncái hěn biāozhǔn，wánquán méiyǒu bìyào róngmào jiāolǜ。

You have a standard figure and there’s no need at all to have social appearance anxiety.
