Scientists from Rutgers University applied four skin creams to hairless mice that were at high risk for developing skin
cancer anyway. Tumor formation increased 69% in the mice that had been moisturized once a day, five days a week for 17
weeks. The creams used in the study included Dermabase, Dermovan, Eucerin and Vanicream.

The authors of the study, which was published online today in the Journal of Investigative Dermatology, say they can't
conclude that moisturizers cause skin cancers in humans. But, according to a story by the Associated Press, lead author
Allan Conney said the study raises important questions.

"I think it raises a red flag indicating that there's a need to determine whether or not these products could cause this
problem in people."

The AP story on the study also quoted several leading dermatologists who cast doubt on the association.

"The components in moisturizers are tested. There's no evidence for this being a problem in humans, " said Dr. Steven
Feldman, professor of dermatology at Wake Forest University.

Moisturizers are not sunscreens, and studies have shown that using sunscreen helps prevent skin cancer. At least we can
be sure of that.

So what if it caused skin cancer in mice? We are not mice. In 2004 there was a study at the University of Reading in the UK that found that methylparaben and phthalates caused cancer in mice. This is an ingredient found in deoderants and moisturisers. This spread and cause fear in people based on false information and assumptions. What they failed to mention was that the amounts that were administered to the mice were 400,000 times greater than what a human would be exposed to.

Take everything you read and hear with a grain of salt and don't be so guillible.

A quick google for University of Reading cosmetics study produced 205,000 hits. Here is the first one on the list:

Chemicals used as preservatives detected in human breast tumours

Release Date : 12 January 2004

New evidence published in the Journal of Applied Toxicology indicates that parabens, chemicals found in underarm cosmetics and other products, can be detected in human breast tumours.

Previous suggestion has been made that certain components of underarm cosmetics may contribute to the rising incidence of breast cancer. Although the connection has yet to be proven, this research at the University of Reading represents an important link that will be crucial to further investigations.

Researchers studied samples of 20 different human breast tumours, measuring the concentration of parabens in the tissue. Intact parabens were detected in the samples, with a mean concentration of 20.6 ng per gram of tissue. The parabens were detected in their ester form rather than metabolite form, which suggests that the route of entry was topical and not oral.

Dr Philippa Darbre, lead author of the study, explains the significance of the results: 'Parabens are used as preservatives in thousands of cosmetic, food and pharmaceutical products but this is the first study to show their accumulation in human tissues. It demonstrates that if people are exposed to these chemicals, then the chemicals will accumulate in their bodies.

'Their detection in human breast tumours is of concern since parabens have been shown to be able to mimic the action of the female hormone oestrogen and oestrogen can drive the growth of human breast tumours. It would therefore seem especially prudent to consider whether parabens should continue to be used in such a wide range of cosmetics applied to the breast area (including antiperspirants/deodorants).'

The results of this study are significant and very important, however they must be interpreted with caution. Dr Philip Harvey, European Editor of the journal and author of a leading editorial piece, states: 'Dr Darbre has forwarded a logical hypothesis and called for further research into the potential link between chemicals used in underarm cosmetics and breast cancer. Unlike diffuse environmental exposures to xenoestrogens, the use of underarm cosmetics presents a special case because of the direct application to the skin.

'The finding of parabens in human tumours is important because it shows that these extraneous weakly oestrogenic chemicals can be detected in the breast and are therefore absorbed. It is clear that these compounds serve no useful purpose in human tissue but further research is required to confirm their route of disposition, persistence and whether they can cause harm.

'Finally, Dr Darbre and colleagues fully peer reviewed finding of parabens in tumour samples does not imply causality of the tumour and further work is required to examine any association between oestrogenic, and other, chemicals in underarm cosmetics and breast cancer.'


It made such and impact that the Womens Community Cancer Project in Cambridge sited it in a newsletter to there members. Here is the first paragraph.

Cosmetics, Parabens, and Breast Cancer
by Rita Arditti

Early this year the media reported that English researchers identified
parabens in samples of breast tumors. Parabens (alkyl esters of
p-hydroxybenzoic acid) are widely used as antimicrobial preservatives
in thousands of cosmetics, personal care products, pharmaceutical
products, and food. There are six commonly used forms (Methylparaben,
Ethylparaben, p-Propylparaben, Isobutylparaben, n-Butylparaben and
Benzylparaben) and it is estimated that they are used in at least
13,200 cosmetics products. According to the lead researcher of the
recent study, Philippa Darbre, an oncology expert at the university of
Reading, in Edinburgh, the chemical form of the parabens found in 18 of
the 20 tumors tested indicated that they originated from something
applied to the skin, the most likely candidates being deodorants,
antiperspirants, creams, or body sprays.

This is not false information or assumptions, the information is out there if you do the research.

(I would post direct links, but can't until my post count grow)

I agree. Stay away from the parabens and pthlates. You don't need them anyway. What's the point in using that JUNK when there are natural ingredients that do the same. Use cosmetics and personal care companies that care more about the ingredients than their bottom line and we will all be better off.
