Cameras sense the visible spectrum, so unless your face is invisible to people's eyes, it'll be visible in a photo.

There are some cheeky ways to defeat flash photography, but flash photos are pretty rare.

Camera's do pick up infrared. Look at the infrared LED on a remote control (while pressing a button) through your phone camera.

Incidentally, "night vision" security cameras exploit this by clustering infared LED's around the lens.

So, you could have some kind of head band that shines LED light down over your face I guess!

Or you could spray your face with this - https://www.phantomplate.com/

That would take care of flash photography at least.
