Forever Chemicals in Skincare vs. Natural Alternatives: What You Need to Know
Share
"Forever chemicals" is a nickname for a group of synthetic compounds known as PFAS (per- and polyfluoroalkyl substances). These substances are prized in cosmetics for their smoothing, waterproofing, and long-lasting properties—but they come with growing concern over their long-term health and environmental impact.
What Are PFAS and Why Are They in Skincare?
PFAS are used in cosmetics to improve texture, spreadability, and wear resistance. You might find them in foundations, mascaras, sunscreens, and lotions. Common PFAS in skincare include PTFE (Teflon), perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS).
They are called “forever chemicals” because they don’t break down easily in the environment or the human body. Studies have shown that PFAS can accumulate over time and are linked to a wide range of health effects, including hormone disruption, immune suppression, fertility problems, and chronic disease risk.
Key Findings from Peer-Reviewed Studies:
A 2021 study in Environmental Science & Technology Letters found PFAS in over half of tested North American cosmetics, often without being listed on the label.
Exposure has been associated with altered thyroid function and changes in sex hormone levels (Johansson et al., 2020).
Several studies link PFAS with longer time to pregnancy, lower IVF success, and diminished ovarian reserve (Jørgensen et al., 2022).
PFAS are associated with reduced vaccine response and increased cholesterol and liver stress (Grandjean et al., 2012; Stahl et al., 2011).
The Case for Natural Skincare
Natural skincare avoids synthetic preservatives, artificial fragrances, and chemical emulsifiers—reducing exposure to potential toxins. Instead, it relies on plant-based oils, hydrosols, waxes, clays, and naturally-derived emulsifiers.
Benefits of Natural Skincare:
Biodegradable & Sustainable: Natural ingredients generally break down more easily, reducing environmental burden.
Lower Toxic Load: Avoiding synthetic chemicals reduces cumulative exposure to endocrine disruptors and allergens.
Nutrient-Rich: Botanical oils and extracts often carry beneficial vitamins, antioxidants, and anti-inflammatory compounds (Dweck, 2005).
Fertility-Safe Formulations: Many natural ranges are free from PFAS, parabens, and phthalates—helping protect hormonal health and reproductive function.
Skin Barrier Support: Natural lipids like squalane, jojoba, and shea butter mimic the skin’s own sebum and can support a healthy barrier function.
Weighing the Risks and Benefits
| Aspect | Conventional (PFAS-containing) | Natural Skincare |
|---|---|---|
| Longevity | Longer wear, water-resistant | May need reapplication |
| Toxicology | Potential bioaccumulation, hormone & fertility disruption | Generally safer with fewer known risks |
| Environmental Impact | Persistent, non-biodegradable | Typically lower footprint |
| Transparency | PFAS often not disclosed | Ingredients more clearly listed |
Final Thoughts
There is no need to panic, but there is good reason to read your skincare labels carefully. At Zurma, we believe in formulating with natural, skin-compatible ingredients because we want to minimise exposure to persistent chemicals and support overall wellbeing. Choosing botanical, whole-plant alternatives means prioritising transparency, environmental care, and skin health in equal measure.
Natural skincare, when formulated correctly, offers effective results without compromising your health or the planet—and that’s a choice we’re proud to stand behind.
