Cosmetics ‘can affect hormones’
CHEMICALS found in beauty products affect women’s reproductive hormones – and could lead to breast cancer, according to research.
The US study examined mixtures of chemicals – such as parabens and benzo phenones – in personal care products in relation to hormones in healthy, reproductive-aged women using several methods of exposure across the menstrual cycle.
Some 500 urine samples were collected from 143 women aged 18 to 44.
Levels of reproductive hormones were shown to either increase or decrease in association with various different chemicals and UV filters, highlighting the complexities of such chemicals.
Certain chemicals were also found to increase levels of oestrogen, which could have a knock-on effect on oestrogen dependent diseases such as breast cancer.
Dr Anna Pollack, assistant professor at George Mason University in Virginia, said: “We may need to be careful about the chemicals in the beauty and personal care products we use.”
