Every Monday, we dedicate a section of the show called Mind Yourself Now to help our listeners with any well-being issues they may have.
On this morning's show, Kate joined Dermot and Dave to reveal how our skin can become healthier and more radiant.
Kate's book 'Glow' was released last Friday, and includes 60 skin nourishing recipes.
The author has professional qualifications in nutrition and cosmetic science - so she knows her stuff!!
Believe it or not, it's mostly down to what you eat...
