In the UK over £9 billion a year are spent on beauty products that promise to improve and transform. But how much of what these products promise is based in scientific evidence, and how much is simply marketing manipulation? Cherry Healey teams up with independent scientists to put everyday cosmetics to the test. In a groundbreaking study carried out by the University of Sheffield, and with the help of 25 volunteers, she discovers that moisturisers might not have the benefits people think they do. She meets dermatologists to find out how well her skin is really aging and sees the shocking effects of sun damage, and she discovers the only over-the-counter product scientists would use on their own wrinkles. Beauty journalist Sali Hughes shows Cherry how to save money on her make-up bag, and with the help of the University of Sunderland she puts common cellulite solutions to the test. She also finds out the truth behind the common claims on cosmetics.
