Silymarin and sun protection

"The milk thistle plant contains silibinin and silymarin, two compounds that are well known for their anti-oxidant, anti-inflammatory properties"

"Topical application of silymarin significantly decreased skin cancer number and size in a validated model of tumor promotion."

"silibinin protects against UV light-induced DNA damage and cancer cell growth."

Steven V. Joyal, MD,' The Sunscreen Paradox - Popular Misconceptions About Skin Cancer Prevention'. 

Silymarin 80% is a natural skin care ingredient taken from the milk thistle plant. There are many studies that show it to be effective as an anti-oxidant, an anti-inflammatory, and for UV protection and repair. It has also been shown to reduce the spread of skin cancer to a certain degree.
