In addition to its benefits for eye health， lutein has also been shown to have anti-inflammatory properties， which can help to reduce the risk of chronic diseases such as heart disease and cancer. Lutein has also been shown to improve skin health and reduce the risk of skin damage caused by UV radiation.
