Sunscreen ‘can enter your bloodstream within one day of use’, study finds

The chemicals in sunscreenenter the bloodstream of users within hours of slapping it on, an American study has found.

The study found that chemicals – avobenzone, oxybenzone, ecamsule and octocrylene – reached levels high enough to trigger a government safety investigation within a day.

The research conducted by America's Food and Drug Administration found that blood concentration continued to rise during the day – and remained in the body for up to 24 hours.

Previous research has suggested that sunscreen ingredients can enter the bloodstream, and have even been detected in breast milk.

Experts have said that people should continue to use sunscreen, due to the risks of skin cancer, but that the results need to be evaluated.

Scott Faber, senior vice president at the Environmental Working Group, or EWG, which publishes an annual guide on sunscreens, says, 'It's not news that things that you put on your skin are absorbed into the body.

'This study is the FDA's way of showing sunscreen manufacturers they need to do the studies to see if chemical absorption poses health risks.'
