BBC Radio 4 - Sliced Bread, Skin care: Collagen and charcoal

Greg Foot is joined by beauty blogger Rebecca Humphries to study the science of skin care.

Science presenter Greg Foot is joined by beauty blogger Rebecca Humphries to look at the facts behind the latest skin care fads. Are they really The Best Thing Since Sliced Bread?

Can collagen face cream reduce wrinkles and make your skin more youthful? Will activated charcoal really purify your pores? Science presenter and YouTuber Greg Foot is on a mission to bust marketing BS, looking for the facts behind the fads and challenging products’ bold claims with scientific evidence.

In the first episode, Greg is joined by actress and beauty blogger Rebecca Humphries, consultant dermatologist Dr Emma Wedgeworth and Cambridge Professor of Chemistry, Melinda Duer. Together they discuss whether collagen face creams really can 'support' or 'boost' collagen production and explore the science behind activated charcoal - could it act as a 'magnet' to draw out dirt and pollution from your pores as some products claim?

While Sliced Bread takes a break, we serve up... Toast.

While Sliced Bread takes a break, we serve up... Toast. Sean Farrington examines the spectacular failures of wonder products and businesses which had promised so much.

While Sliced Bread takes a break we serve up... Toast. A study of the spectacular failures of brands which had promised so much to consumers.    

In each episode, the presenter and BBC business journalist, Sean Farrington, examines one big idea. What did it promise? Why did people back it? Why did they get burnt?  

Some of the world's most successful businesses have also brought us some of the world's most remarkable failures. So, what led them to be toast? And what can we learn from their stories today? 

Sean unpicks all the early optimism, hype and ambition. He learns about the tremendous success of a brand before hearing how it faltered, with help from expert commentators and people who were directly involved. How do they view things now and what, if anything, could have been done differently? 

The self-made millionaire and serial entrepreneur, Sam White, is alongside him, analysing the missteps that changed a brand's fortunes and reaching her own, often instructive, conclusions.  

From big tech to high street retail and, of course, food, Toast tackles the business ideas that, one way or another, ended up cooked. 

Sliced Bread returns for a new batch of investigations in February. In the new series, Greg Foot will investigate more of the latest so-called wonder products to find out whether they really are the best thing since sliced bread. In the meantime, Toast is available in the Sliced Bread feed on BBC Sounds.

Toast is a BBC Audio North production for BBC Radio 4.
