Heard anything about this?

Shallee,

Yes, there certainly is science behind the comments. My hunch is that Rio Tan is not the best place to find the science, and they are capitalizing on some of the new products that were introduced this year. If I am not mistaken Rio, is also Millenium, Squeeze and about 6 other companies. Most likely a different label wrapped around the same lotion with a difference fragrance. Buyer beware.

That being said, yes the research on Caffeine does have some validity. It was conducted at my father’ Alma Mater Rutgers University. I have pasted a copy of the AP article below.

We actually started using Caffeine in combination with high amounts of Camellia Sinensis, and Camellia Olieifera (green and black tea, years ago, however, this past year created a line specifically promoting the concept earlier in the year)

There are a lot of people that have seen and heard about this report, it was nationally aired several months ago and picked up by most of the news medias, and so people have a very general concept of the benefits.

I think you will see just about every lotion company introduce a product with some variation on this theme by years end. The positive press on Caffeine, makes for good marketing. You just heard about it from Rio first, because they immediately release the 50 or so telemarketers to promote the newly label old goo.

Aug. 26 — Caffeine, the chemical stimulant in coffee and tea, has been found to lower the risk of skin cancer in laboratory mice. A study suggests that a skin lotion spiked with caffeine or with another compound found in green tea can reduce by more than half the number of cancer tumors on the skin of hairless mice exposed to brutal levels of

“WE HAD between 50 to 70 percent tumor formation inhibition in the mice that were treated with caffeine or with EGCG (the other chemical compound),” said Dr. Allan Conney, senior author of a study appearing this week in the online site of the Proceedings of the National Academy of Sciences.

Skin cancer is the most common of all cancers in the United States. The American Academy of Dermatology estimates about a million cases will be diagnosed in the country this year. Among them will be more than 88,000 new cases of melanoma, the disease’s deadliest form. Skin cancer generally is curable by cutting, burning or freezing the tumor cells, but untreated it can be deadly.

STUDY DETAILS
To test effects of caffeine on skin cancer, Conney, a professor of cancer and leukemia research at Rutgers University in New Brunswick, N.J., and his colleagues exposed 90 mice to high levels of ultraviolet radiation twice a day for 20 days. They used a strain of animals, called hairless mice, commonly used for skin cancer studies.

After the mice got their UVB doses, the animals were divided into three groups. One group were slathered daily with a solution of acetone and caffeine. Another group received acetone and EGCG. The third group got skin applications of acetone only. Acetone is an organic solution often used on the skin.
At the end of 18 weeks, the three groups of mice were killed, and the level of skin tumor formation was analyzed.

Conney said mice in all three groups developed malignant skin tumors, called squamous cell carcinomas, but the number of tumors per mouse was reduced by 72 percent in those treated with caffeine and by 66 percent among those treated with EGCG, compared to the controls treated only with acetone.

The treated mice also had fewer nonmalignant, sunlight-related tumors, said Conney. Compared to the control group of mice, the mice treated with caffeine had 44 percent fewer nonmalignant tumors, the EGCG group 55 percent fewer, hConney said that although both compounds were effective in lower tumor risk, caffeine has an advantage because it is chemically more stable than EGCG.

Unlike sunscreen lotions, which protect against skin cancer by preventing the skin from absorbing ultraviolet rays from the sun, the caffeine’s cancer protection works in the cells after exposure to the ultraviolet rays. Rays from the sun can cause genetic changes in the skin that can lead to skin cancer.

Conney said caffeine apparently blocks this action by causing abnormal cells to kill themselves, a type of programmed cell suicide that prevents development of abnormal growths.

“This is not a sunscreening effect,” said Conney. “It is a biological effect.”
He said the caffeine acts selectively, causing the abnormal cells to die but not affecting the normal cells.
Dr. Darrell Rigel, a professor of dermatology at New York University and an expert spokesman for the American Academy of Dermatology, said research like Conney’s is needed badly because “skin cancer is a major problem. I hope this treatment can prove itself, because there are more skin cancers than all other cancers combined in the U.S.” he said. Ultra violet radiation.
