(Newser) – Moisturizers used by millions around the world each day may increase skin cancer in mice, the Daily Mail reports. But many more tests are needed before researchers can draw conclusions about humans. In mouse experiments, animals primed to develop skin cancer were exposed to UV light. The moisturized mice developed non-melanoma cancers at a faster rate than the others, as well as twice as many tumors.

“While the research is interesting,” one scientist said, “I don't think any conclusions should be drawn from it at this stage.” Other dermatologists echoed that idea, saying mice offer little insight into human skin. Humans are designed for sun exposure, while the rodents are not.
