Make-up and skincare could leave women infertile or even cause breast cancer
Make-up and skincare products contain a cocktail of chemicals that could leave women infertile and even cause breast cancer.
These chemicals include parabens and BPA, which are considered ‘gender benders’ due to them encouraging male breast growth.
After analysing more than a 100 women, US scientists found those who have these chemicals in their urine produce abnormal amounts of the reproductive hormones oestrogen and progesterone.
Excessive oestrogen has been linked to fibroids and polycystic ovary syndrome, while too little prevents eggs maturing and being released from the ovary. Too much progesterone is associated with both breast cancer and unusual vaginal bleeding.
Previous research suggests parabens, which are used as preservatives in cosmetics and skincare, mimic oestrogen and may cause cancer, while Bisphenol A (BPA), which is added to perfumes to make scents last longer, has been linked to infertility.
Lead author Dr Anna Pollack said: ‘This study is the first to examine mixtures of chemicals that are widely used in personal care products in relation to hormones in healthy, reproductive-age women, using multiple measures of exposure across the menstrual cycle, which improved upon research that relied on one or two measures of chemicals.
