A study has found that topical applications of moisturizers such as Dermabase, Dermovan, Eucerin Original Moisturizing Cream, or Vanicream could increase skin cancer risk.
Irradiated mice who were treated with the moisturizers exhibited a significant increase in their rate of tumor formation and increase in tumor size per mouse. Treatment of the mice with Dermabase, Dermovan, Eucerin, or Vanicream for 17 weeks increased the total number of histologically characterized tumors by 69 percent.
According to the study, as reported by Green Med Info:
"The results indicate that several commercially available moisturizing creams increase the rate of formation and number of tumors when applied topically to UVB-pretreated high-risk mice. Further studies are needed to determine the effects of topical applications of moisturizing creams ... in humans."
This also applies to tanning oils and lotions—which many of you may be using right now with summer in full swing—as well as the baby oil or lotion that many parents unwittingly slather on their babies.
