In Australia, beauty blogger Emma Markezic took three natural deoderants for a week-long test run to determine efficacy.
Results were disappointing. The first, a roll-on, had the consistency of “tar on a new highway” and did nothing for the subject’s “William Shatner-levels of sweatiness.” The second, a paste, performed better but felt like “Vegemite” under her arms and had an unpleasant odor. Ms. Markezik’s third experiment, a homemade deoderant made of lemongrass, was similarly disappointing.
Conventional deoderant works by plugging up sweat ducts with aluminum. Though efficacious, there are concerns that such products can cause Alzheimer’s and increase the risk of breast cancer.
