A few weeks ago we met Chrissy, a young girl with terrible eczema who was about to travel across the world for treatment.
We followed her journey to the tiny village of Avène, in the south of France.
Thousands of people flock here each year to breathe, bathe and drink from its waters which some claim has a healing quality.
