People absorb many hazardous chemicals from popular sun creams and sprays. The chemicals can cause cancer and development and reproductive problems. The chemicals are absorbed through the skin and enter the bloodstream where amounts have been detected up to hundreds of times above recognized safety levels.
The blood plasma samples where a too high level of chemicals where found are from people who have applied the creams and sprays correctly, and according to the guidelines recommended by the manufacturer. The US Food and Drug Administration (FDA) has set a safety threshold of 0.5 mg / ml in blood plasma for the active ingredients in most sunscreens. But levels up to 209 mg / ml have been detected by FDA researchers, who tested four popular sunscreen products on 24 volunteers.
Any level above 0.5 mg / ml should activate an automatic toxicological assessment because the chemicals – avobenzone, oxybenzone, octocrylene and ecamsule – can be carcinogenic and can disrupt healthy development and reproduction.
In the test, the four sunscreens – two sprays, one lotion and one cream – were applied to the volunteers, whose blood plasma was tested. Oxybenzone was most easily absorbed, with levels as high as 209.6 mg / ml being detected.
