Makeup, skin care contains chemicals that can make women infertile and cause breast cancer

A new study has now found that makeup and skin care products contain a cocktail of chemicals that can leave women infertile and even cause breast cancer.

The chemicals included in these products include parabens and BPA, which are considered "gender factors" because they promote breast growth in men.

After analyzing more than 100 women, US scientists have found that those who have these chemicals in their urine produce abnormal amounts of estrogen and progesterone, reproductive hormones.

According to the experts, excess estrogens have been associated with fibroids and polycystic ovary syndrome, while too little prevents egg maturation and release from the ovaries.

On the other hand, too much progesterone is associated with breast cancer and unusual vaginal bleeding.

In addition, studies have already shown that parabens, used as preservatives in cosmetics and skin care, mimic estrogen and can cause cancer. Bisphenol A (BPA), added to scents that produce odors, lasts longer and is associated with infertility.

The research, conducted at George Mason University, Virginia, analyzed urine samples from 143 healthy women, all pre-menopausal and not taking a contraceptive.

On the findings, lead author, Dr. Anna Pollack, said the study was the first to look at blends of chemicals widely used in personal care products versus hormones in age-healthy women to procreate. cycle, which has improved compared to research based on one or two measurements of chemicals.

Women provided between three and five urine samples on two menstrual cycles. These have been evaluated for BPA chemicals, parabens, chlorophenols and benzophenones.

Chlorophenols are used as preservatives in cosmetics and have been associated with acne, liver damage and cancer.

Benzophenones are added to products like lip balm and nail polish to protect them from UV rays. They also prevent products like soap from losing their color and smell. Studies have linked benzophenones to cancer and infertility.

Blood samples were taken from all participants to determine their hormone levels – estrogen, progesterone, FSH and LH.

The findings, published in the journal Environment International, suggest that exposure to all the chemicals studied increases progesterone levels in women.

People with higher levels of chlorophenols in their urine also produce more estrogen and FSH, while parabens and BPA increase estrogen levels.

While too much ostroegen is linked to the estrogen dominant condition, which can lead to non-cancerous growths in the uterus and PCOS, chlorophenols are associated with reduced estrogen production, of FSH and LH. Low levels of FSH suggest that a woman does not produce eggs, whereas a reduced LH may be a sign of PCOS.
