A Third Proof-of-Concept Study to Evaluate the Efficacy of NOBO, a Novel Postbiotic, in Controlling Axillary Odor in Healthy Adults

The goal of this clinical trial is to evaluate the performance of NOBO, a yeast-based fermentation product (postbiotic) designed to control axillary odor, in controlling axillary odor in healthy male and female adults age 18 - 70 with confirmed self-perception of body odor. The main question it aims to answer is: Does NOBO decrease self-perceived odor of the intervention axilla compared to the placebo axilla at any time point? Researchers will compare the intervention axilla odor score to the placebo axilla odor score to see if there is a difference in self-perceived odor. Participants will: * be given a NOBO deodorant spray and a placebo deodorant spray (each assigned to one axilla) * self assess body odor * self assess skin irritation
