Every day, women (and men) worldwide slather on moisturizing creams of all prices and varieties, trying to keep the skin supple and defy aging. From our mothers advice on skin care, and reinforced by modern media, facial creams have always been considered a must-do ritual. However, several moisturizers were presented to promote the spread of skin cancer and tumor growth in mice exposed to UV light. Does this mean you need to leave and forget everything you learned? No, it simply means that you must read the label more carefully to be absolutely sure.

Hairless mice were exposed to UV radiation twice weekly for 20 weeks. The UV treatment was followed by the application of four brands of skin moisturizer to the skin of animals, five days a week for a period of 17 weeks. The treatment resulted in the generation of non-melanoma skin cancer.

The research group, from Rutgers University in Piscataway, New Jersey, discovered that mice treated with skin moisturizers showed an increased rate of tumor formation and found that more tumors developed on mice treated with moisturizers than those treated with UV radiation. The rate of increase in tumor activity from the application of each moisturizer in the analysis were:
24 per cent for the Eucerin Original Moisturizing Cream (Beiersdorf, Hamburg, Germany)
58 per cent for Vanicream (Pharmaceutical Specialties Inc., Rochester, Minnesota)
69 percent Dermabase (Patrick Laboratories in Minneapolis)
95 percent Dermovan (Galderma Laboratory Inc Fort Worth, Texas)



Researcher Allan H. Conney of the University of Susan Lehman Cullman Laboratory for Cancer Research noted, "we have tested these creams are tumorigenic (cancer causing) activities." He also said, "I need to stress that what we have done is only in mice. We do not know what are the implications for humans. But he is not pose a red flag that something that should be taken into consideration. "

Some ingredients in moisturizers have been identified as printing to enhance the growth of the tumor. When the mineral oil and sodium lauryl sulfate, already linked to skin irritation, were removed from the lotion in a mix created for the analysis of Johnson & Johnson, the change in the lotion did nothing to promote cancer growth in mice exposed to UV light.

"We do not really know what the ingredients that make these creams," Conney said. "There is a need for the various companies test their creams to see whether or not a problem." Conney believes that companies can remove the effect of the modification of their products. He added: "I'm sure there are creams on the market that do not have tumorigenic activities and some of them have anti-tumor activity in May."

Is non-melanoma skin cancer very common in humans and is usually curable surgically. However, it can be fatal in very rare cases. Conney said that further studies are needed to determine the effects of topical creams on humans since the skin of mice is thinner and more porous than human skin. Many experts doubt the importance of the study to humans.

It is important to note that consumers should not simply stop using moisturizers. As we age and our skin becomes drier, moisture is necessary to avoid conditions such as the appearance of redness, eczema and dermatitis.
