Question about the skin glow effect of quitting flour

 
I am in my 30s and I love bread and noodle dishes so much that I make sure to eat flour-based food for at least one of my three meals a day. However, lately I have been worried because I feel my skin texture has become more uneven and my complexion has turned dull.

I have heard many people say that simply cutting out flour makes your skin glow and improves your complexion. Is this really effective, both medically and through actual experience?

I am wondering if there are dramatic changes beyond simple dietary control.

If I put this into practice, for how long do I need to endure it to see results?

I am curious about the reviews.
