Naringin Beste Antioxidant Anti-aging Naringin at a glance A biolflavonoid antioxidant found in certain foods, like citrus Allows skin to better defend itself when exposed to environmental threats Can assist in reinforcing the skin’s natural supply of antioxidants Naringin description Naringin is a biolflavonoid antioxidant found in certain foods, including citrus fruits. Naringin is what gives grapefruit its bitter taste, but it can also be found in onions, tomatoes, figs and apples. Along with being an antioxidant, naringin has documented soothing properties and has potential to maintain or improve various aspects of bodily health when foods that contain it are routinely consumed. Applied to skin, naringin, like potent antioxidant glutathione, can help shore up skin’s natural supply of antioxidants, allowing them to work longer before breaking down. This benefit allows skin to better defend itself when exposed to environmental threats like UV light and pollutants. Use levels of naringin in cosmetics are typically recommended between 0.1–0.5%; however, lower amounts are sometimes used to support the efficacy and stability of other antioxidants and/or to help protect the integrity of the formula. Note: Naringin is a glycoside (sugar derivative) of the flavonoid naringenin, whose antioxidant and soothing benefits are nearly identical to naringin. Of note, naringenin has superior efficacy when it comes to protecting lipids from oxidation, but both help protect skin from environmental damage.
