Should we be using different razors on different areas of the body to avoid spreading “bad” bacteria or is this a myth?

Many of the areas of your body share similar microorganisms. The ratio of organisms is largely dictated by physical aspects of the skin. Razors may possess the ability to transfer organisms to other parts of the skin, but we do not believe it poses a significant hazard for the introduction of pathogenic organisms to other parts of the body. If there is concern, cleansing your razor between use would limit this.
