Women Beware! Your Everyday Beauty Products May Have Cancer-Causing Chemicals

While beauty routines are typically associated with self-care and health, a new study paints a shocking picture of what is possibly being stored in the bottles on our bathroom shelves. A recent study found in Environmental Science & Technology Letters finds that formaldehyde and formaldehyde-releasing preservatives, which are identified human carcinogens, are widely present in a vast array of beauty products used by women all over the world. And alarmingly, the people most affected are often unaware of the risks they face daily.In a long-term observational study, Silent Spring Institute researchers monitored the at-home personal care practices of 70 Black and Latina women in Los Angeles for 5-7 days. The subjects provided ingredient lists and usage records for the products they used in the home and found the surprising trend: 53% of the subjects reported using products that had formaldehyde or formaldehyde-releasing agents present.What Is Formaldehyde and Why Is It Used?Formaldehyde is a pungent, colorless gas with broad use for its antimicrobial activity. In cosmetics, it is used as a preservative to increase shelf life and inhibit bacterial growth. But for all its useful purposes, it has a dark side: formaldehyde is a carcinogen according to several health organizations, including the U.S. National Toxicology Program and the International Agency for Research on Cancer.Formaldehyde-releasing preservatives like DMDM hydantoin and quaternium-15 are also commonly substituted for formaldehyde. These chemicals gradually release small amounts of the chemical, offering continued protection against contamination—but possibly releasing cancer-causing agents with each use.Among these products were:Shampoos and conditionersBody washes and lotionsEyeliner and eyelash adhesiveHand soaps and skin lightenersOne respondent used three formaldehyde-formulated products daily: a leave-in conditioner, a rinse-off conditioner, and a body wash. Others utilized hand soaps with formaldehyde agents several times daily—indicating repeated and consistent use.Throughout the study, the 64 women used a total of 1,143 beauty products. Each woman, on average, applied 17 different products daily, with some applying as many as 43. This amount of exposure highlights the cumulative risk of toxic chemicals in daily regimens."Repeated exposures such as these can accumulate and do significant harm," explained Dr. Robin Dodson, senior author of the study. "It's not hair straightener anymore—it's everywhere that these chemicals are."This problem doesn't impact all women the same. Black and Latina women are especially at risk because of socio-cultural and economic pressures that lead to conformity to Eurocentric beauty ideals. Regular use of chemical hair relaxers, skin lighteners, and other specialized products puts these communities at increased risk for health effects—such as breast, uterine, and ovarian cancers, which disproportionately impact Black women."This is all of the legacy and history of discrimination," said Black Women for Wellness co-author and executive director Janette Robinson Flint. "We shouldn't have to be chemists to know whether our products will make us ill."Even though formaldehyde was designated a human carcinogen more than a decade ago, regulatory intervention in the United States has lagged and has been inadequate. The FDA had made plans in 2023 to propose prohibiting the use of formaldehyde in hair straighteners. However, two years down the line, no concrete action has been made.Meanwhile, the European Union prohibited formaldehyde in cosmetics back in 2009. Formaldehyde and its releasing agents are also subject to strict labelling in the UK if found in concentrations above specific levels.Several U.S. states, such as California and Washington, have introduced or implemented bills regulating these ingredients in cosmetics—but their efficacy is uncertain.What to Watch for on Labels?One of the biggest problems consumers have is that formaldehyde-releasing ingredients are not always labeled clearly. Rather than "formaldehyde," you might find chemical names such as:DMDM HydantoinImidazolidinyl UreaDiazolidinyl UreaQuaternium-15BronopolThese are complicated and unfamiliar to most people, so it is difficult for consumers to make informed decisions.Other Toxic Chemicals to AvoidFormaldehyde is only one ingredient in the toxic mix in many personal care products. Other ingredients of concern include:Benzophenone: A UV filter tied to hormone disruptionParabens: Estrogen-mimicking preservatives tied to breast cancerHydroquinone: Skin-lightening agent prohibited in most countriesTriclosan: Antimicrobial now limited due to health and environmental issuesPPD (p-phenylenediamine): Hair dye ingredient tied to allergic reactionCoal tar and mica: Identified irritants and possible carcinogensNatural Alternatives for Your Beauty RoutineThe best news is that you don't have to sacrifice safety for beauty. Here are detox tips for your beauty routine:Go natural: Opt for products with fewer ingredients and familiar names. Ingredients such as shea butter, coconut oil, aloe vera, and beeswax are moisturizing and harmless.Select certified clean brands: Opt for brands that have been certified by EWG Verified, USDA Organic, or those meeting EU cosmetic regulations.DIY solutions: Consider homemade masks, scrubs, and hair oils using simple kitchen ingredients.Shop small and local: Many indie brands are more transparent about their ingredient sourcing and often offer customizable, preservative-free products.Stay informed: Use apps like Think Dirty or EWG’s Skin Deep to scan and evaluate products before purchase.The responsibility for knowing what's in our products cannot rest with the average consumer alone. "We need real regulatory action to protect women," stated Dr. Dodson. "Reading labels isn't enough—we need bans on toxic ingredients."Until now, awareness, education, and advocacy are the strongest defense. Your health is more valuable than any marketing slogan—read past the gloss and select beauty that doesn't have to come at the expense of well-being.
