Resh and Casey are in rural Mexico investigating how candelilla wax - a common ingredient in many beauty products - is produced. The plant-based wax is often marketed as a vegan and ethical alternative to beeswax, but they're shocked to see farmers producing the wax by handling sulphuric acid with no safety equipment.The group visit the headquarters of one of the biggest beauty brands in the world, Benefit Cosmetics, and have the chance to question the founder's daughter, Maggie Ford-Danielson. The group discovers how hard beauty brands work to protect their image, and discover that one of the biggest threats to that image is the millions of counterfeit products being sold all over the world.
