In this programme, Catalyst uncovers the secrets to healthier skin, gets up close and personal with some of the most common rashes, spots and blemishes - and shows you how to care for the largest organ in your body. And where better to do that than at the beach? With the help of a team of Australia's top dermatologists we'll find out why skin health is more than a cosmetic issue. We'll learn what we can all do to keep our skin working well for us at any age. We'll find out some surprising facts about moisturiser - and look at how technology is being used to help in the detection and protection against skin cancer. And in the burns unit of ground-breaking Australian surgeon Fiona Wood, we'll meet some of the patients benefiting from her work and find out the latest science around regenerating and protecting skin in trauma.
