The Hidden Endocrine Disruptors in Everyday Cosmetics
Most people apply several cosmetic products before they've had breakfast. Rarely does anyone ask what happens when those products' ingredients are combined.
The Most Studied Substances
A recent systematic review identifies the most commonly discussed hormonally active substances in cosmetic products: parabens, phthalates, benzophenones, and triclosan. Its authors emphasise that these substances rarely occur in isolation—daily use of multiple products can result in complex, combined exposures that may have additive effects, even when each individual ingredient is considered safe on its own.
How Widespread This Is
The European Commission has prioritised several cosmetics-relevant substances for endocrine-disruptor assessment, including benzophenone-3, propylparaben, triclosan, octocrylene, homosalate, and octinoxate. A large consumer-product analysis found 55 different endocrine-disrupting or asthma-associated compounds across common products, including parabens, phthalates, fragrance components, and UV filters.
A Brief History
As early as the late 1990s, research led by Edwin Routledge and colleagues described estrogenic activity in several parabens. In 2004, parabens were detected in breast tumour tissue. A causal link to cancer has not been conclusively established to date—but the evidence base is part of why we take a cautious approach.
Our Approach
Rather than removing individual "problem ingredients" one at a time, we choose to build every formula from the ground up without this entire substance class: no parabens, no phthalates, no triclosan, and no hormonally flagged UV filters in any product we make.
This article summarises published research on ingredient classes generally. It is not a claim about any individual health outcome, and is not medical advice.
