scare-moisturizer-150.jpg<\/span> suggests that some common moisturizers might speed up the development of skin cancer—at least in laboratory mice.<\/p>\n Don’t throw out your lotions and creams just yet, though. More work is needed to determine what this means for human moisturizer users, according to Allan Conney, PhD, the senior investigator of the study published Thursday in Journal of Investigative Dermatology<\/em><\/a>. Moisturizers are medically necessary for some people, and animal studies don't directly point to human risk.<\/p>\n At most, the study is a "red flag that there could be a potential problem," says Conney, who is the director of the laboratory for cancer research at the Rutgers University School of Pharmacy in Piscataway, N.J.<\/p>\n What the study found<\/strong> They assumed that commercially available moisturizer would be a good way to deliver caffeine to the skin of mice, until they discovered a side effect.<\/p>\n In the new study, the researchers exposed hairless mice to ultraviolet light twice a week for 20 weeks, which increased the animals' risk of skin cancer. They applied either nothing, water, or one of four different creams—Dermabase, Dermovan, Eucerin Original Moisturizing Cream, or Vanicream—to the skin of the mice. This went on 5 days a week for an additional 17 weeks (the model is meant to mimic a common human pattern: sunlight exposure in childhood, followed by an adulthood with less sun exposure.)<\/p>\n About 81% of the mice treated with water or nothing developed some type of skin tumor—squamous cell carcinoma<\/a> or other easy-to-treat tumors, not the more dangerous melanomas<\/a>—from ultraviolet light exposure. For those with cream, the cancer incidence ranged from slightly lower (79%) to significantly higher (90%), depending on the type of cream.<\/p>\n In addition, the size of the tumors developed more rapidly and were larger in the moisturizer-treated mice than in controls—40.6 to 51.3 cubic millimeters, as opposed to 27.3 cubic millimeters in the untreated mice.<\/p>\n
Ironically, Conney and his colleagues went down this path because previous research suggested caffeine might protect against cancer if it was rubbed on the skin.<\/p>\n
