Dr Kerri Purdy speaks with Dr Vincent Richer, a dermatologist and expert in lasers and phototherapy in Vancouver, BC.

Dr Kerri Purdy speaks with Dr Melanie Pratt, a world-renowned expert on contact dermatitis. This is part two of our look at the Sherlock Holmes world of contact dermatitis. Treating this mysterious condition requires clinicians to trade their lab coats for detective caps as they hunt around for clues and search for allergens and irritants in fragrances, products and even furniture.

As you will hear, the process of discovering the culprit behind contact dermatitis is often far from elementary. In this episode, Drs Purdy and Pratt explore some of the most common irritants and allergens found in products.
