Deodorant 101


We all use an antiperspirant or deodorant on a daily basis, but many are unaware of what the differences between these two products actually are. Just in time for the official start of summer, Barrie Drewitt, “Odor Guru” at Princeton Consumer Labs (an independent lab that tests claims made by deodorant companies), is here to fill us in on all the facts. Barrie will give viewers an overview of how he tests product efficacy via smelling, and share the technical differences between antiperspirant and deodorant, best practices for application, and how to decide which form is best for your viewers’ needs.
