Summary

This study tested whether a new deodorant spray called NOBO, made from a yeast-based postbiotic, can reduce underarm odor. Five healthy adults who felt they had body odor used NOBO on one armpit and a placebo spray on the other. They rated their own odor and provided samples for lab testing to see if NOBO worked better than the placebo.
