The chocolate has the chemical that makes flamingos pink. Scientists say the chemical can make the skin of a 50 to 60-year-old look 20 years younger. People can see changes in their skin in just three weeks. It took over ten years of research to make. Over 3,000 people took part in tests. The chocolate is only in boxes of 21 bars.
