With more than 30,000 IR lights used to scan a detailed map of your face, FaceID can distinguish

These infrared waves are visible beyond the spectrum of light, so your iPhone won’t blind your eyes in the dark. With a combination of proximity and ambient light sensor, your iPhone can sense when you’re about to use your phone, thus instantly unlocking it once it sees your face.

This automatically unlocks your phone as soon as it senses you want to unlock it.
