Women with skin of color have higher levels of beauty-product related chemicals in their bodies compared to white women, according to a commentary published in the American Journal of Obstetrics and Gynecology.
“Pressure to meet Western standards of beauty means Black, Latina and Asian American women are using more beauty products and thus are exposed to higher levels of chemicals known to be harmful to health,” says Ami Zota, ScD, MS, an assistant professor of environmental and occupational health at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. “Beauty product use is a critical but underappreciated source of reproductive harm and environmental injustice.” Zota and Bhavna Shamasunder at the Occidental College in Los Angeles co-authored the commentary.
The authors say even small exposures to such toxic chemicals can lead to health problems and that reproductive health professionals must be prepared to counsel patients who have questions about such exposures.
They also say that previous studies have documented that Black, Latina and Asian American women spend more on beauty products than the national average, often because of marketing practices that emphasize a European standard of beauty. For example, women of color buy products like skin lightening face cream which often contain hidden ingredients such as topical steroids or the toxic metal mercury, Zota says.
Black women are known to suffer more anxiety about having “bad hair” and are twice as likely to experience social pressure to straighten their hair. Hair products like straighteners or relaxers are likely to contain estrogen and can trigger premature reproductive development in young girls and possibly uterine tumors, the duo writes.
Other studies show that beauty and personal care products contain multiple, hidden chemicals that are linked to endocrine, reproductive or development toxicity. They can be especially dangerous for women age 18 to 34, the authors say. Women in this age group are known to be heavy buyers, purchasing more than ten types of beauty products per year. Such women and their offspring may experience heightened vulnerability to such chemicals, especially if exposure occurs during sensitive periods such as pregnancy.
Marketing efforts have also encouraged Black women to use douching products with messages about uncleanliness and odors. A study done by Zota and colleagues in 2016 found that in a national sample of reproductive age women, those who reported douching frequently, had 150 percent higher exposures to a harmful chemical known as DEP. This chemical, often found in fragranced beauty products, may cause birth defects in babies and has also been linked to health problems in women, Zota says.
At the same time, research suggests that low-income women of color are more likely to live in an environment with high levels of pollutants contaminating the air, soil and water. Thus women of color are not only heavy users of beauty products but may also be exposed to toxic chemicals simply by living in a more polluted home or neighborhood.
“For women who live in already polluted neighborhoods, beauty product chemicals may add to their overall burden of exposures to toxic chemicals, says Bhavna Shamasunder, as assistant professor in the Urban and Environmental Policy Department at Occidental College, in a news release. “Certain racial/ethnic groups may be systematically and disproportionately exposed to chemicals in beauty products since factors such as institutionalized racism can influence product use.”
In the commentary, the co-authors warn that multiple exposures to chemicals in beauty products and in the environment add up and can interfere with healthy reproduction and development.
"This article is interesting as it does highlight the importance of seeking care from a board-certified dermatologist for recommendations on prescription and nonprescription based skin care products," says Skin of Color Society President Seemal R. Desai, MD, a dermatologist at Innovatove Dermatology in Plano, Texas. "The skin lightening industry is a multimillion dollar industry especially in parts of the world were lighter skin culturally is associated with higher socioeconomic status." Dr. Desai reviewed the article for Dermwire.
Hydroquinone is the gold standard in topical skin lightening for the prescription perspective, and there are multiple derivatives of that that are available in some over-the-counter formulations, he says. "The problem becomes when you have preservatives and additives in products and you cannot actually tell what the active ingredients are. Mercury, Lead, Copper are just three of the metals I have heard of in these products, and yes systemic absorption can happen."
