How to prevent use of a photo to bypass face recognition screen lock?

I remember that when facial recognition started to be used as a method to unlock smartphones, one criticism was that a photo of the owner could be used to bypass it. Has this been improved? How can you prevent someone from using a photo of you if you use this lock method?
I have facial recognition on my LG, and in the lock screen settings, there is an option to require blink to unlock. This means that unless someone figures out how to make a photo blink, it will be pretty difficult to use a picture to bypass your facial recognition screen lock.
I suggest using a passcode rather than face recognition. It might take a second or two to tap it in, but that's far better than worrying that somebody might use a photo to unlock your phone.
