Inhibits acne bacteria and deodorizes: Farnesol has efficacy against Propionibacterium acnes (the acne bacterium) and other microbes on skin. In acne treatments, it helps reduce bacterial count and inflammation in pores. Farnesol is also commonly used in natural deodorants – it suppresses odor-causing bacteria, thus reducing body odor. Additionally, it imparts a light, floral scent. In summary, farnesol provides a mild antimicrobial action that can benefit acne-prone skin and serve as a fragrance/deodorant component.
