Why don't have all people the same colour of the skin? Why does the skin peel, if you rest too long in the sun? Why do we perspire? What's that - the keratin? Why is our skin impermeable? And, where has acne its origins?

Fred, Jamy and Sabine explain us everything about the skin that - thanks to its 200.000 nerve endings - informs us steadily about the world around us and protects us against exterior impacts. Being in Ouistreham, the centre of thalassotherapy, they explain us the role of the skin and its multiple particularities.
