SUNDAY August 17, 2008 (foodconsumer.org) — A new study by researchers from Rutgers University suggests that some moisturizing creams or moisturizers may significantly increase the risk of a type of skin cancer called Squamous cell carcinoma.
The study showed hairless mice that were pre-treated with UV radiation to induce skin damage and the received topical treatment with 100 mg of Dermabase, Dermovan, Eucerin, or Vanicream for 17 weeks were 69%, 95%, 24% and 58% respectively more likely to develop skin cancer.
The study was published Thursday in the Aug. 14, 2008 issue of the Journal of Investigative Dermatology. Some researchers doubt that moisturizers would pose such a risk in humans saying mice are not humans and results from animal studies may not always be applicable to humans.
But Allan Conney and his colleagues are no ordinary researchers. They are highly regarded and well respected in the cancer research. Their findings can’t be discounted with ease although further investigation is needed to confirm the effect of moisturizers in humans.
According to Conney, two chemicals used in the moisturizers are likely culprits for the increased risk. They are mineral oil and sodium laurel sulphate. The researchers made a custom blend cream without these ingredients and found their moisturizer was not tumorigenic in the mice.
News reports said Rutgers and Johnson & Johnson have jointly patented the custom blend moisturizer, but it is unknown whether this product would be ever commercialized.
This study draws quite some attention from the media and readers because moisturizers are so commonly used by many people believing that they would benefit their skin.
