When you see the word "fragrance" listed on a skincare product, you probably think nothing of it. It smells good, right? But that seemingly innocent word can mask a whole host of potentially harmful chemicals. In fact, "fragrance" is often a blanket term used by brands to hide a complex blend of synthetic compounds—some of which have been linked to skin irritation, hormonal disruption, and even cancer. Let’s explore what’s really in your skincare fragrance and why it matters to your health.
What exactly is "Fragrance" in skincare?
In the personal care industry, "fragrance" has become a vague, catch-all term used to describe a mixture of chemicals used to create a particular scent. What’s particularly concerning is that the specific ingredients used in fragrances are often not disclosed. According to the U.S. Food and Drug Administration (FDA), fragrance formulas are considered trade secrets, so companies are not required to break down the components of their scents. This means that a product labeled with the single word “fragrance” could contain dozens of chemicals that you're not aware of—and some of those could have serious health risks.
The health risks of hidden fragrance chemicals
Fragrance chemicals can cause a range of issues, from skin irritation to more severe long-term health concerns. Here are some of the most concerning effects associated with certain fragrance ingredients:
-
Skin Irritation
One of the most immediate risks of synthetic fragrances is skin irritation. Chemicals like synthetic musks (which mimic the scent of natural musk) and phthalates (used to make scents last longer) can trigger allergic reactions or irritate sensitive skin. These reactions can manifest as redness, itching, rashes, or eczema. -
Hormonal Disruption
Phthalates, commonly used in fragrances, are known endocrine disruptors. This means they can interfere with the body’s hormone systems, potentially leading to reproductive issues, developmental problems in children, and an increased risk of certain cancers. Studies have shown that phthalates can alter the production of hormones such as estrogen and testosterone, which can have lasting effects on both men and women. -
Respiratory Issues
In addition to skin problems, the inhalation of fragrance chemicals can also lead to respiratory issues. Chemicals like benzophenones, found in some sunscreens and scented products, have been linked to asthma and other respiratory conditions. Formaldehyde, which can be released from some fragrance chemicals, is a known carcinogen that can damage the respiratory system and increase the risk of cancer. -
Cancer Risk
Perhaps one of the most alarming concerns is the potential link between certain fragrance chemicals and cancer. Formaldehyde, which is found in some fragrance mixes, has been classified as a human carcinogen by the International Agency for Research on Cancer (IARC). Long-term exposure to formaldehyde has been associated with an increased risk of nasopharyngeal cancer and leukemia. Additionally, certain synthetic musks and other chemicals used in fragrances have raised concerns for their potential carcinogenic effects.
Common toxic ingredients to watch out for
While the term "fragrance" can hide dozens of ingredients, some of the most commonly used and most concerning include:
Phthalates: Used to make fragrances last longer, phthalates have been linked to reproductive harm and developmental issues. They can be absorbed through the skin and inhaled, affecting both men and women.
Benzophenone: Found in many fragrance formulas, benzophenones can cause skin irritation and have been linked to hormone disruption.
Formaldehyde: A known carcinogen, formaldehyde is sometimes used as a preservative in fragranced products. Even low-level exposure can have serious health risks, including respiratory problems and an increased risk of cancer.
Synthetic Musks: Chemicals like moskene and galaxolide are often used to mimic the scent of natural musk. These compounds can accumulate in the body over time and have been associated with hormone disruption.
How to Avoid Harmful Fragrances
Read labels carefully: If you see the word "fragrance" listed without further details, it's a red flag. The safest way to shop is to choose products that provide full transparency about their ingredients, particularly when it comes to scents.
Use a label-scanning app: Reading labels can be daunting and time consuming, but the good news is there are apps out there (some of which are free) that can decipher the ingredients and give you a score. We recommend SkinScore.
Opt for fragrance-free or naturally scented products: Look for skincare products that are labeled "fragrance-free" or those that use natural essential oils for scent, such as lavender, rosemary, or citrus. These oils are less likely to cause irritation and are often safer for your skin and hormones.
Know the brands you trust: Choose brands that disclose all of their ingredients and avoid using "fragrance" as a catch-all term. Brands committed to transparency often go the extra mile to ensure their products are safe for your health.
The word "fragrance" might sound harmless, but it can be a hidden danger in your products. From skin irritation and hormone disruption to respiratory issues and an increased risk of cancer, fragrance chemicals can have serious health implications. By being an informed consumer, reading labels carefully, and opting for fragrance-free or naturally scented products, you can protect your skin and your health from the harmful effects of these hidden ingredients.
