About this episode

The episode explores the effectiveness of home red-light therapy devices for skin care and their scientific backing.

Home red-light therapy devices have exploded in popularity as masks, body wraps and mittens promise to reduce wrinkles, redness and even acne. But do the claims stack up, and what other benefits are scientists investigating? Ian Sample hears from his co-host, Madeleine Finlay, and the consultant dermatologist Dr Jonathan Kentley. Kentley explains how the potential benefits of red light were discovered, how it is thought to interact with collagen in our skin, and what science has to say about its impact on our appearance.
