P. acnes can exacerbate acne as a result of the inflammatory properties of the cell wall short chain fatty acids and chemotactic factors. Here, researchers investigate the effectiveness of a magnolia extract as an acne treatment, based on the known anti-inflammatory and antimicrobial effects from magnolol and honokiol within the material.

The antioxidant potential of cosmetic materials can be evaluated by several methodologies, including a commercial kit that measures total antioxidant status, as illustrated here with a commercial extract from the fruit of the açaí, a Brazilian palm tree. Applications in antiaging products are suggested.
