What’s the problem?

Sweat odor needs five precursors to emerge. Warmth and moisture from the body and the surrounding and a hosting surface such as the fibers on our clothes provide a perfect home for the bacteria, which feed on the fat and protein from our sweat and emit odors during their metabolic activities. Is that the bacteria or the odor that is the problem? Let’s tackle the real problem: odors.​
