Caffeine protects mice from skin cancer when rubbed onto their skin as a solution, a study in the US found. The results were almost as impressive with a second solution containing epigallocatchin gallate (EGCG), an extract from green tea.
“We’re hopeful that lotions containing these substances might have the potential for inhibiting sunlight-induced skin cancers,” says Allan Conney, head of the team which tested the solutions at Rutgers, the State University of New Jersey.
“But we don’t know if these substances are effective in humans,” he cautions. “The next step is to try experimental lotions on people at extra risk of sunlight-induced skin cancers.”
