Melissa and Jam explore the fascinating chemistry behind self tanners. They take listeners on a journey from the discovery of the key sugar in self tanners in the 1960s by Dr. Eva Wittgenstein to the present-day scientific understanding. The episode delves into the Maillard reactions, typically known for browning food, explaining in simple terms how similar reactions color the skin when self tanners are used. Additionally, the hosts discuss the molecular structure of carbohydrates, the generation of free radicals, and the temporary UV sensitivity following self-tanner application. Interactive elements like pop quizzes and listener shout-outs keep the discussion engaging and educational, while also touching on recent studies and encouraging community support. The episode is a blend of fun facts, thorough biochemistry, and practical advice for achieving a safe, sun-kissed look.
