A sleep and glow pillow is called just that because:

1. It’s made to help you sleep much better than you are now
2. When you sleep well, you glow the next day

What is glowing meant to mean?

When your face and skin “glow”, you should (in theory) look younger. You look brighter. And mentally, your brain is more active and alert after a good night’s sleep.

This is opposed to a more tired, sagging, eye bag appearance as a result of poor sleep quality night after night.
