If I cut out flour, will my skin really glow?

Lately, I often hear stories from people around me saying their skin has improved dramatically after cutting out flour.

I heard that it brightens the complexion, reduces blemishes, and gives off a natural glow from within. I'm wondering if there is actually a scientific basis for this. I really love bread and noodles, so I'm worried that it will be hard to quit them completely.

I would like to know if the problem is simply with the flour itself, or if it is due to the sugar or oil added when making flour-based foods. I would like to hear firsthand experiences and advice from those who have actually seen noticeable changes or effects on their skin after cutting out flour.
