Uncovering the Facts about Sunscreen

  1. Studies fail to prove sunscreens prevent basal cell cancers and melanoma, yet most public health officials still insist that sunscreen use or or abstinence from the sun is our best protection.
  2. Oddly enough, since the introduction of chemical sunscreen, skin cancer rates began to climb and not fall. For example, melanoma rates doubled from 6 to 13 per 100,000 people since 1973. Today, skin cancer diagnoses surpass all other cancer, with over 1.3 million new cases each year, with new melanoma diagnoses to be close to 48,000 in 2002, according to the American Cancer Society.
  3. Research shows sunscreen does not protect against melanoma, the most dangerous form of skin cancer. Lotions decrease the risk of sunburn, they do not block UVA rays, which cause melanoma. Even sunscreens with the highest protection factor of 35, applied in the correct amounts, were not effective at filtering out the harmful rays. They say that people should limit their sunbathing time and use clothing to block UVA rays when sun is at its strongest.


Absorbing the Truth about Sunscreen

Recently, a study in the April 2004 Journal of Chromatography found that there is significant penetration of all sunscreen agents they studied into the skin, and oxybenzone and metabolites across the skin. Concentrations of Benzphenone 3 and its metabolite, 2’4 dihydroxybenzophenone, have been found in human urine only four hours after application. They have also been found to be absorbed from the gastrointestinal tract and bioaccumulation of them has been detected in human milk samples.

  1. Benzophenone and oxybenzone (benzophene 3) are among the most powerful free radical generators known. (In 1997 sunscreen chemicals such as benzophenone and ethylhexyl- p-methoxycinnimate, and PABA esters such as padimate-o and octyl dimethyl PABA were banned by the European community.)
  2. Octy Methoxycinnamate (OMC), may be dangerous if it gets into the bloodstream. As far back as the 1970s, Professor Howard Maibach discovered that as much as 35% of sunscreen enters the bloodstream and the longer it is on the skin, the more absorbed.
  3. Triethanolamine (TEA) when applied topically to female mice, shows an increase in liver tumors, whereas male mice had a smaller increase in liver tumors but also developed kidney tumors. TEA combined with water or nitrates (often used as a preservative but not required by law to be listed) can produce nitrosomines, which are carcinogenic.
  4. Parsol 1789 is a chemical which blocks UVA but is also a free radical generator and skin penetrant.
  5. 2-phenylben zimidazole-5-sulfonic acid (PBSA), an ingredient found in some sunscreens, and has been shown to damage DNA when exposed to light.
  6. Chemicals known as estrogen surrogates, or gender benders, are suspected of causing reproductive disorders in animals and humans. Such disorders include deformed or stunted growth of genitalia and may be, in part, responsible for the dramatic rise in cancers of the prostate, breast, testicles and uterus. 7- Chemicals in sunscreens were found in fish in Germany turning some of the fish into hermaphrodites.

  8. Benzphenone-3, homosalate octyl-methoxycinnimate, 4-methylbenzlidene (4mbc) camphor and octyldimethyl-PABA (o-d-PABA) are all estrogen mimickers, and all were shown to increase cell growth in breast cancer cells! Three of these cells were found to cause developmental problems in animals, and 4mbc, when mixed with olive oil and spread on the skin of rats at concentrations permitted in sunscreen, doubled the uterine growth rate before puberty, a very shocking and disturbing discovery. The presence and exposure to estrogen mimickers are and should be of monumental concern, for when these estrogenics make contact with hormone receptors, they are interpreted as the real thing (estrogen) and the results are the feminization of tissue. This may lead to developmental problems that can lead to endometriosis, uterine and breast cancers, disruption of the menstrual cycle and other problems for women. In men, it may lead to testicular cancer, breast enlargement, lower sperm counts, loss of sex drive and more.
