Fortunellin is primarily used in the cosmetic and pharmaceutical industries due to its antioxidant and anti-inflammatory properties. It helps protect skin cells from oxidative stress caused by UV exposure and environmental pollutants, making it a valuable ingredient in anti-aging skincare formulations. Its ability to inhibit certain enzymes involved in inflammation also supports its use in soothing sensitive skin and reducing redness. Additionally, Fortunellin is being studied for potential benefits in promoting metabolic health and supporting natural defense mechanisms in the body, which could expand its use into functional foods and dietary supplements.
