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.
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:
One 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.
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:
These are complicated and unfamiliar to most people, so it is difficult for consumers to make informed decisions.
Formaldehyde 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 disruption
Parabens: Estrogen-mimicking preservatives tied to breast cancer
Hydroquinone: Skin-lightening agent prohibited in most countries
Triclosan: Antimicrobial now limited due to health and environmental issues
PPD (p-phenylenediamine): Hair dye ingredient tied to allergic reaction
Coal tar and mica: Identified irritants and possible carcinogens
The 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.

On February 13, Canadians across the country mark Wear Red Canada Day, a reminder that heart disease remains the leading cause of death for women. Yet despite the scale of the problem, many women still do not recognize their risk or their symptoms.
“We’re learning more and more each day about how heart disease uniquely affects women,” said nurse practitioner and researcher Rachel Ollivier in an interview with CTV News. She emphasized that awareness is still lagging, both among patients and within health-care systems.
According to the World Health Organization, cardiovascular disease accounts for roughly one in three deaths among women globally. In Canada, heart disease and stroke continue to be leading causes of death among women, and women are less likely than men to receive timely diagnosis or treatment.
Chest pain remains the most common heart attack symptom in both men and women. But Ollivier explained that women’s symptoms can often be subtler or feel different.
“For women, they often uniquely experience chest pain that seems like more of a discomfort or a tightness in the chest,” she said. Some women may feel pain in the left arm or jaw, unusual fatigue, nausea, vomiting, or discomfort between the shoulder blades.
Because these symptoms can be less specific, they are sometimes dismissed as stress, anxiety, indigestion, or exhaustion. Social factors also play a role. Women often juggle multiple responsibilities at home and work, and may delay seeking care. In some cases, their concerns may also be minimized within health-care settings.
Medical differences matter too. Women typically have smaller hearts and arteries, and plaque buildup behaves differently compared to men. Conditions such as spontaneous coronary artery dissection and microvascular dysfunction are seen more commonly in women, making diagnosis more complex.
Beyond symptoms, experts are urging greater recognition of the role hormones play in lifelong heart health.
“Endogenous estrogen is cardio protective,” Ollivier explained. As women enter the perimenopausal transition, estrogen levels fluctuate and gradually decline, and that protection is lost. This shift can lead to higher cholesterol levels and changes in fat distribution, increasing cardiovascular risk, particularly between the ages of 40 and 60.
Colleen Norris, a nursing professor at the University of Alberta and research lead of the CKHui LHHW Women’s Heart Health Research Collaborative who wrote on Yahoo Canada, believes the conversation needs to go even deeper.
She argues that ovaries have long been viewed only through the lens of reproduction. “The ovaries are not just reproductive organs. They are architects of women’s health across the lifespan,” she noted. Estrogen influences the heart and blood vessels, but also the brain, bones, kidneys, metabolism, and immune function.
Most women are never told that ovarian reserve and estrogen levels begin declining in their late 30s. By the time noticeable symptoms appear, biological changes may have already been underway for years.
Menopause itself is just one day, Norris explained. The larger reproductive transition surrounding it is what significantly increases vulnerability to chronic disease. Yet the health-care system often waits until disease develops before intervening.
Both experts stress that education is critical. Women with conditions such as polycystic ovary syndrome, pregnancy complications like preeclampsia or gestational diabetes, and those entering midlife should be particularly mindful of their cardiovascular risk.
Wear Red Canada Day is meant to spark awareness, but symbols alone are not enough. Experts are calling for better research funding focused on midlife women, improved medical education around ovarian aging, and more proactive screening during the reproductive transition.
Heart disease in women is not inevitable. But recognizing that symptoms can differ, and that hormonal shifts matter, could be lifesaving.

Seychelles Chikungunya Virus Outbreak: The United States warned travelers to be careful if they plan to visit the Seychelles islands anytime soon as it is currently undergoing a chikungunya outbreak. As per the Centers for Disease Control and Prevention (CDC), a 'Level 2' advisory for the island has been issued and travelers have been asked to 'practice enhanced precautions' if they do plan to visit.
Chikungunya is a mosquito-borne viral disease transmitted primarily by Aedes aegypti and Aedes albopictus, the same mosquitoes that spread dengue fever. Symptoms typically appear three to seven days after a bite and include sudden fever, severe joint pain, headache, nausea, fatigue, and rash in about half of cases.
However, there are certain unique symptoms of chikungunya. For instance, unlike a Dengue fever, chikungunya leaves lingering effects along with joint pain and fatigue that lasts up to weeks.
While common symptoms like high fever often >102 degree F is common there are other symptoms too, which includes:
Chikungunya symptoms usually occur with in 3 to 7 days after a bite. However, the symptoms could often last long. While fever could subside in a day or two, chronic symptoms especially like joint pain and muscle pain could last for months. Weakness too could persist.
A Level 2 travel advisory has been issued, which means the travelers are expected to practice enhanced precautions as compared to a Level 1 advisory that only asks travelers to practice usual precautions.
In more serious cases, Level 3 advisory is issued that asks travelers to reconsider non-essential travel, whereas a Level 4 advisory asks travelers to avoid all travel.

Why do some relationships feel effortless and magnetic, while others slowly unravel despite our best intentions? According to neuroscientist Andrew Huberman, the answers lie deep within our early childhood experiences and the intricate wiring of the brain.
In a recent episode of Huberman Lab titled “Essentials: The Science of Love, Desire & Attachment,” Huberman explores how biology and psychology work together to shape the way we connect, commit, and sometimes drift apart. What makes the conversation compelling is how it bridges hard science with very human emotions.
Huberman begins with a powerful idea: the way we love as adults often echoes how we were loved as children.
He refers to the landmark “Strange Situation” experiment by psychologist Mary Ainsworth. In this study, toddlers were briefly separated from their caregivers and then reunited. Researchers closely observed how the children reacted. Some felt secure and soothed upon return. Others were anxious, avoidant, or distressed.
These early attachment patterns, Huberman explains, frequently resurface in adult romantic relationships. A securely attached child may grow into a partner who trusts and communicates well. An anxious child may become someone who fears abandonment. An avoidant child may struggle with emotional closeness.
The hopeful part? These patterns are not destiny. Awareness allows change. Once people recognize their emotional blueprint, they can reshape it.
Romantic connection is not housed in a single “love center.” Instead, multiple brain regions activate in sequence to create desire, attraction, empathy, and long term bonding.
Huberman clears up a common myth about dopamine. Many people think of it as the pleasure chemical. In reality, it is more about motivation and pursuit. Dopamine fuels craving and drives us toward a person we find compelling. It is the chemical that makes you check your phone, wait for a message, or feel a rush at the thought of someone.
But desire alone does not sustain love.
For deeper attachment, empathy circuits come into play. The prefrontal cortex and the insula are especially important. The insula helps us sense our internal bodily state, a process known as interoception. It allows us to feel our own emotions while tuning into someone else’s. This shared emotional awareness strengthens bonds.
One of the most fascinating ideas Huberman discusses is what he calls “positive delusion.” For long term stability, the brain benefits from believing that your partner is uniquely special. This slight bias, almost a romantic illusion, reinforces commitment.
It is not about ignoring flaws. It is about genuinely feeling that this person, out of billions, holds a singular place in your emotional world. Biologically, this strengthens attachment pathways.
Huberman also references research from the Gottman Lab at the University of Washington. Decades of data reveal four behaviors that predict relationship breakdown: criticism, defensiveness, stonewalling, and contempt.
Stonewalling happens when one partner emotionally withdraws and stops responding. But the most toxic behavior is contempt. Researchers have described it as acid to a relationship because it corrodes trust and shuts down empathy. Once contempt takes root, the neural circuits that support connection begin to weaken.
In the end, love is both chemistry and choice. Our brains may set the stage, but awareness, empathy, and daily behavior determine whether attachment deepens or quietly falls away.
