How do these companies come to that conclusion? I think most people start to smell after only 24 or 48 hours max so how do these companies get 72 hours out of their testing?
Im assuming they’re fudging their numbers but at what point does it become false advertisement?
If I had to guess, someone in Marketing noticed that the 48-hour protection sold better than the 24-hour protection, so they decided to put 72-hour on the label
Who isn’t using deodorant daily?
