• Skin cancer prevention. One of the most exciting findings of recent years concerns the potential skin-protective effect of milk thistle extracts. Researchers found that topically applied milk thistle extract protects the skin of mice exposed to chemical carcinogens from skin tumor formation.7 Further studies in mice demonstrated that topically applied milk thistle extract protects the skin of mice against ultraviolet light-induced skin cancer.22 Further studies are indicated to explore the potential skin cancer-protective effects of topical application and internal consumption of milk thistle in humans.
That info is at the very tail end of that article…but the proposed anti-cancer benefit of milk thistle’s silymarin is the inhibition of the egf receptor, stopping cancer from spreading. Interesting. Its not very soluble in water, but an aqeous solution with warm water probably could be made and smeared in hydrated, warm skin without resorting to any potential ‘anti-infective’ agent like an alcohol.
