Chemicals in Personal Care Products – What Are We Really Absorbing?

Studies point to a connection between chemicals in cosmetics and hygiene products and negative effects on both physical and mental health. One notable study, conducted by the University of California, Berkeley, together with the Salud del Valle de Salinas clinic, examined the impact of a short break from using products that contain hormone-disrupting chemicals.

New Study: Three Days, Significant Change

In a study published in Environmental Health Perspectives, 100 teenage girls were given hygiene products labeled as free from phthalates, parabens, triclosan, and oxybenzone—common chemicals found in many personal care items such as shampoo, soap, sunscreen, and cosmetics.

Study results: After just three days of using “clean” products, researchers recorded a 27% to 45% drop in chemical levels in the participants’ bodies. This included a noticeable reduction in parabens, phthalates, and triclosan.

The Possible Effects of Daily Exposure

There is growing scientific evidence linking chronic exposure to chemicals in personal care products to hormonal disruptions, developmental issues, psychological challenges, and even serious illnesses such as cancer.

According to Dr. Kim Harley of the University of California:

“Women are the primary consumers of personal care products, and they may be especially vulnerable to these chemicals—particularly during adolescence, a time of rapid hormonal change.”

How to Protect Yourself: Spotting Harmful Ingredients

Before buying personal care products, it's important to read the ingredient list carefully. These are some of the most common and concerning substances:

Dioxane

Nitrosamines

Phthalates

Parabens

Formaldehyde

Triclosan

Vinyl pyrrolidone and vinyl acetate copolymers

Synthetic fragrances

The Solution: Switching to Natural Products?

Choosing natural or organic hygiene products can reduce the levels of chemicals in the body. However, it’s important to remember that even items labeled “natural” or “organic” are not always free of harmful ingredients. Always check the label thoroughly.

Frequently Asked Questions About Chemicals in Personal Care Products

Do all cosmetics contain harmful chemicals?
Not all, but many do contain phthalates, parabens, or synthetic fragrances. Always read the label.

What’s the difference between “natural” and “organic” products?
“Natural” doesn’t necessarily mean chemical-free. “Organic” refers to how the ingredients were grown (without pesticides), but the product can still contain synthetic substances.

Is daily use really harmful?
Research shows that continuous exposure may lead to the accumulation of harmful substances in the body and disrupt hormonal systems.

How can I choose safer hygiene products?
Look for products with a short, clear list of ingredients—free from artificial fragrances, triclosan, and phthalates. Consider natural alternatives based on essential oils.
