Lipsticks, lip glosses, and lip balms may contain PFAS (per- and polyfluoroalkyl substances), also known as "forever chemicals," which manufacturers add to improve texture, durability, and water resistance. These man-made compounds can be absorbed through the skin or accidentally ingested when you apply lip products, contributing to overall exposure to chemicals linked to cancer, hormone disruption, and fertility problems .

What Are PFAS and Why Are They in Your Lip Products?

PFAS have been detected in a wide range of cosmetics and personal care products, including foundations, mascaras, and lipsticks. These chemicals are prized by manufacturers because they repel water, grease, and stains, making products last longer on the lips. However, the same properties that make them useful also make them dangerous: PFAS do not break down in the body or environment, earning them the nickname "forever chemicals" .

The problem is that many of these chemicals may not be clearly listed on product labels. Some PFAS are listed under names such as PTFE, ethanolamines, or perfluoro-compounds, though not all are declared. According to the source material, ethanolamines are chemicals made up of amino acids and alcohols, and they can be absorbed through the skin or ingested when you apply lip products .

Research has linked PFAS exposure to serious health concerns. Because these chemicals do not degrade, they accumulate in the body and environment over time. Long-term exposure has been associated with cancers, immune suppression, hormone disruption, and fertility issues .

Why Lip Products Are a Significant Exposure Route?

Lip products are applied directly to the mouth multiple times per day, making them a significant exposure route for toxic chemicals. Unlike other cosmetics that sit on the skin's surface, lip balms and glosses are frequently ingested as they wear off or are licked away. This means any PFAS or other harmful chemicals in these products have a direct pathway into your bloodstream .

The accumulation of PFAS in the body is particularly concerning because these chemicals are persistent. Studies suggest that repeated low-level ingestion contributes to the build-up of these chemicals over time. For people who use lip gloss or lipstick daily, this exposure compounds significantly over months and years .

"These compounds are highly toxic and pose a clear potential danger to human health, as they act as endocrine disruptors, in addition to causing liver damage, thyroid disease, obesity and being associated with fertility problems and cancer," explained Dr. Julian Campo, an expert in environmental toxins at the University of Valencia.

How to Choose Cleaner Lip Care Products

• Read ingredient labels carefully: Look for products that explicitly state they are PFAS-free or "forever chemical-free." Avoid products listing PTFE, ethanolamines, or perfluoro-compounds, which are common names for PFAS in cosmetics.
• Choose natural and organic lip balms: Opt for lip balms made with simple, recognizable ingredients like beeswax, shea butter, coconut oil, or plant-based waxes instead of synthetic formulations designed for extended wear.
• Prioritize brands with transparency: Select cosmetic companies that publicly disclose their full ingredient lists and have committed to removing PFAS from their formulations, particularly smaller clean beauty brands focused on non-toxic cosmetics.
• Minimize water-resistant formulas: While water-resistant lip products may seem convenient, they often rely on PFAS to achieve that durability. Traditional lip balms without water-resistance claims are typically safer alternatives.
• Test patch before full use: When switching to new lip products, apply a small amount first to ensure compatibility with your skin and to reduce overall exposure to any potentially harmful ingredients.

The challenge for consumers is that there is no requirement for manufacturers to clearly list which chemicals have been used in cosmetic formulations. This lack of transparency makes it difficult to know exactly what you are applying to your lips each day .

The good news is that awareness is growing. More clean beauty brands are reformulating their lip products to exclude PFAS and other synthetic chemicals. By reading labels carefully and choosing products from brands committed to transparency, you can significantly reduce your exposure to these "forever chemicals" and protect your long-term health.
