Teacher Liu, I saw a news story saying a girl had an MRI scan and the machine went black because she was wearing makeup. Is that true?

Yes, it’s true. Some cosmetics contain metal components, which can interfere with MRI scans.

I used to think light makeup was fine, and even more polite that way.

A lot of people think that, but MRI machines are very sensitive to metal, so wearing makeup can actually be unsafe.

So even just foundation or lipstick isn’t okay?

It’s best to remove everything. Glitter, eyeshadow, and setting spray need extra caution.

I see—this is really informative. Health checks are more important than looking good.

Exactly. In China people often say ‘health comes first.’ Keeping it simple and clean before an exam is being responsible to yourself.
