Silymarin is a flavonoid that comes from the fruit and seeds of milk thistle. It has been used for centuries as a treatment for liver diseases such as cirrhosis , jaundice and hepatitis. It’s a great example of natural, preventive medicine because it protects the liver from incoming toxins, as well as helps the liver to cleanse itself – from alcohol, drugs, medications, mercury, pesticides, anesthesia to name a few. Following along with the theory that silymarin cleanses the liver, supplement marketers claim that these benefits will extend to the skin and result in a natural healthy glow as well as treat underlying skin issues. Because silymarin has anti-inflammatory properties, topical applications are marketed to treat conditions such as acne, eczema, and rosacea. As with all anti-oxidants, more research is required to determine whether it can effectively be absorbed by the skin when applied topically. In the meantime a nutritional supplement containing this flavonoid might be the best way to ensure your liver is getting the support it needs – healing your skin from the inside out.
