Microplastics in Cosmetics: 87% of Products Contain Them

87% of Your Cosmetics Likely Contain Microplastics

Every morning, millions of people apply moisturizer, foundation, sunscreen, and lip balm without a second thought. But a groundbreaking study by the Plastic Soup Foundation revealed a staggering reality: 87% of cosmetic products from major global brands contain microplastics or synthetic polymers. That means nearly nine out of every ten beauty products sitting on your bathroom shelf are depositing tiny plastic particles onto your skin, into your pores, and eventually into the environment.

The cosmetics industry has quietly relied on microplastics for decades. These microscopic plastic particles — typically smaller than 5 millimeters — serve as exfoliants, emulsifiers, film-forming agents, and texture enhancers. They make your foundation smoother, your scrub grittier, and your moisturizer silkier. But the hidden cost is enormous: these particles persist in the environment for hundreds of years, accumulate in marine ecosystems, and are increasingly linked to human health concerns including endocrine disruption and cellular inflammation.

In this comprehensive guide, we break down exactly which microplastic ingredients lurk in your cosmetics, which product categories are the worst offenders, what health risks researchers have identified, how the EU is responding with landmark regulation, and — most importantly — how you can protect yourself starting today.

What Are Microplastics in Cosmetics?

Microplastics in cosmetics fall into two broad categories: primary microplastics, which are intentionally added during manufacturing, and secondary microplastics, which form when larger plastic packaging degrades. The concern with cosmetics is primarily about intentionally added microplastics — synthetic polymers that companies deliberately include as functional ingredients.

Unlike the visible plastic in packaging, these particles are often invisible to the naked eye. They can be solid beads, liquid polymers, or semi-solid gels. The Plastic Soup Foundation's “Beat the Microbead” campaign analyzed over 7,000 products and found that many well-known brands use dozens of different synthetic polymers across their product lines. Some individual products contained as many as 10 to 15 different plastic ingredients.

The European Chemicals Agency (ECHA) estimates that approximately 42,000 tonnes of intentionally added microplastics are released into the environment in the EU alone each year, with cosmetics and personal care products contributing a significant share of that total.

The 6 Most Common Microplastic Ingredients in Cosmetics

Learning to identify microplastics on ingredient labels is the single most powerful step you can take to reduce your exposure. Here are the six most prevalent synthetic polymers found in beauty and personal care products:

1. Polyethylene (PE)

Polyethylene is the most widely used plastic in the world, and it is also the most common microplastic found in cosmetics. In beauty products, PE appears as tiny beads in exfoliating scrubs, as binding agents in pressed powders, and as film-forming agents in mascaras and eyeliners. Before the US Microbead-Free Waters Act of 2015, polyethylene microbeads were the primary exfoliant in hundreds of facial scrubs. While solid microbeads have been restricted in rinse-off products in some countries, PE in other forms — such as waxes and emulsifiers — remains widespread. Look for “Polyethylene” or “PE” on ingredient labels.

2. Polypropylene (PP)

Polypropylene is commonly used as a bulking agent and texture enhancer in lipsticks, foundations, and eye shadows. It helps create the smooth, spreadable consistency that consumers expect from high-end cosmetics. PP microparticles are also found in some exfoliating products as alternatives to the now-restricted PE microbeads. Because PP is chemically inert, manufacturers consider it “safe” — but its environmental persistence and potential to carry adsorbed pollutants tell a different story. Check labels for “Polypropylene” or “PP”.

3. Polymethyl Methacrylate (PMMA)

PMMA is a transparent thermoplastic often sold under trade names like Plexiglas. In cosmetics, it appears as microspheres that create a soft-focus, blurring effect on the skin. This makes it incredibly popular in anti-aging creams, primers, and foundations marketed as “pore-minimizing” or “line-smoothing.” A 2020 study published in Environmental Science & Technology found PMMA particles in 62% of the foundation products tested. Look for “Polymethyl Methacrylate” or “PMMA” in the ingredients list.

4. Nylon (Polyamide)

Nylon microparticles are used extensively in color cosmetics. They appear in eyeshadows, blushes, bronzers, and setting powders as bulking and opacifying agents. Nylon-12, in particular, is a favorite of cosmetic formulators because it creates a silky, luxurious feel and helps powders adhere to the skin. It also appears in mascara formulations to add volume and length. Research from the University of Plymouth found that a single application of powder makeup containing nylon can release thousands of microplastic particles. Watch for “Nylon-6”, “Nylon-12”, or “Polyamide” on labels.

5. Polyethylene Terephthalate (PET)

PET is the same plastic used to make water bottles, and in cosmetics it appears primarily as glitter and shimmer particles. Many nail polishes, body glitters, highlighters, and eyeshadows contain PET microparticles that create their sparkle. A study by researchers at Anglia Ruskin University demonstrated that cosmetic glitter has measurable negative effects on freshwater ecosystems, reducing chlorophyll content and root growth in aquatic plants within 36 days. The environmental impact is compounded by the fact that glitter particles are almost impossible to capture in wastewater treatment. Look for “Polyethylene Terephthalate” or “PET”.

6. Polyurethane (PUR)

Polyurethane functions as a film-forming agent in many cosmetic products. It creates the long-lasting, waterproof barrier in products like setting sprays, waterproof mascaras, and long-wear foundations. It is also found in some nail polishes where it contributes to chip resistance. Because polyurethane forms a persistent film on the skin, there are growing concerns about its potential to trap other chemicals against the skin surface and enhance transdermal absorption of other cosmetic ingredients. Check for “Polyurethane” or “PUR”.

Which Cosmetic Categories Are Worst Offenders?

Microplastics are not limited to one type of product. They have infiltrated virtually every category of personal care. Here is a breakdown of where they are most prevalent:

Skincare Products

Facial moisturizers, serums, anti-aging creams, and eye creams are among the most heavily contaminated categories. The Plastic Soup Foundation found that over 90% of skincare products from the top 10 global brands contained at least one synthetic polymer. Microplastics serve as emulsifiers (keeping oil and water mixed), viscosity regulators (controlling thickness), and film-forming agents (creating a smooth barrier). Products labeled “long-lasting,” “pore-filling,” or “smoothing” are particularly likely to contain PMMA or silicone-based polymers.

Makeup and Color Cosmetics

Foundations, concealers, powders, eyeshadows, lipsticks, and mascaras frequently rely on nylon, PE, PP, and PMMA for texture, adhesion, and optical effects. A 2022 study by the Dutch National Institute for Public Health found that a typical makeup routine involving foundation, concealer, powder, eyeshadow, and mascara could expose the wearer to over 30 different synthetic polymers in a single application.

Sunscreen

Many chemical sunscreens use synthetic polymers to improve the even distribution of UV filters on the skin and enhance water resistance. Acrylates copolymer and acrylates/C10-30 alkyl acrylate crosspolymer are among the most common. These polymers wash off during swimming and bathing, contributing directly to marine microplastic pollution. Research published in Marine Pollution Bulletin estimated that recreational beach use releases approximately 14,000 tonnes of sunscreen into ocean waters annually, with a significant portion containing synthetic polymer ingredients.

Shampoo and Hair Care

Shampoos, conditioners, hair masks, and styling products use microplastics for conditioning, detangling, and hold. Dimethicone (a silicone polymer), polyquaternium compounds, and acrylates copolymers are ubiquitous in hair care formulations. Because these are rinse-off products, the microplastics they contain flow directly into wastewater systems, where conventional treatment plants capture only 65% to 92% of microplastic particles, allowing the rest to enter rivers and oceans.

Toothpaste

Before regulatory action, many leading toothpaste brands included polyethylene microbeads for a “deep clean” sensation. While solid PE beads have been banned in rinse-off products in the US, EU, UK, and several other jurisdictions, some toothpastes still contain other synthetic polymers like PEG (polyethylene glycol) derivatives and carbomer (a polyacrylic acid polymer) as thickeners and stabilizers. Dentists have reported finding microplastic particles embedded in patients' gum tissue, raising concerns about chronic oral exposure.

Exfoliating Scrubs

Facial and body scrubs were historically the most visible source of microplastics in cosmetics. A single tube of exfoliating scrub could contain up to 330,000 microbeads, according to research by the United Nations Environment Programme (UNEP). While legislation in many countries has targeted microbeads in rinse-off products, leave-on exfoliating treatments — such as chemical peels and overnight exfoliating masks — may still contain synthetic polymer particles that remain on the skin for extended periods.

Health Risks: What Microplastics in Cosmetics Do to Your Body

The health implications of microplastic exposure through cosmetics are a growing area of scientific concern. While research is still evolving, several significant findings have emerged:

Skin Absorption and Penetration

A 2023 study published in Environment International demonstrated that nanoplastics (particles smaller than 1 micrometer) can penetrate the outer layer of human skin, the stratum corneum, and reach the viable epidermis beneath. This is particularly concerning because cosmetics are designed to be applied directly to the skin, often on the face where skin is thinner and more permeable. Damaged or compromised skin — from conditions like eczema, acne, or even post-procedure sensitivity — may allow even larger microplastic particles to penetrate deeper layers.

Once absorbed, microplastic particles can act as carriers for other harmful chemicals. Many synthetic polymers used in cosmetics are known to adsorb (bind to their surface) heavy metals, persistent organic pollutants, and other toxins. Research from the University of Birmingham found that microplastic particles recovered from cosmetic products carried concentrations of phthalates, parabens, and UV filters on their surfaces that were up to 1,000 times higher than the surrounding product matrix.

Endocrine Disruption

Perhaps the most alarming health concern is the link between microplastics and endocrine disruption. Many synthetic polymers contain or leach chemicals that mimic natural hormones, particularly estrogen. A landmark 2024 study published in the New England Journal of Medicine found that individuals with microplastics detected in their carotid artery plaque had a 4.5-fold increased risk of heart attack, stroke, or death over a 34-month follow-up period compared to those without detectable microplastics.

Bisphenol A (BPA) and phthalates, commonly associated with plastic manufacturing, are known endocrine disruptors that have been linked to reproductive issues, thyroid dysfunction, metabolic disorders, and increased cancer risk. When microplastic particles from cosmetics enter the body, they may release these chemicals slowly over time, creating chronic low-level exposure that accumulates throughout a person's lifetime. For a deeper dive into these health effects, read our guide on microplastics and human health.

Cellular Inflammation and Oxidative Stress

Laboratory studies using human skin cell cultures have shown that exposure to microplastic particles triggers inflammatory responses, including increased production of pro-inflammatory cytokines like interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha). Chronic inflammation is a well-established precursor to numerous diseases, including cardiovascular disease, autoimmune conditions, and cancer. A 2023 study in Science of the Total Environment found that polystyrene microplastics induced significant oxidative stress in human dermal fibroblasts, the cells responsible for producing collagen and maintaining skin structure. This suggests that microplastic exposure through cosmetics could paradoxically accelerate skin aging — the very condition many of these products claim to combat.

The EU Microplastics Ban: A Timeline for Change (2025–2035)

The European Union has enacted the most comprehensive regulatory response to microplastics in cosmetics through its restriction under REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals). Here is the key timeline:

• October 2023: The EU formally adopted the restriction on intentionally added microplastics under REACH Annex XVII. This covers synthetic polymer microparticles that are less than 5mm in any dimension, are organic, insoluble, and resist degradation.
• October 2025: Rinse-off cosmetic products containing microbeads (solid microplastic particles used for exfoliation) must be reformulated or removed from the EU market. This is the first enforcement deadline.
• October 2027: Leave-on cosmetic products — including moisturizers, foundations, serums, and sunscreens — must eliminate intentionally added microplastics. This is the most impactful deadline for the beauty industry as it affects the largest number of products.
• October 2029: Lip products, nail products, and makeup intended for use near mucous membranes must comply. These categories received an extended timeline due to reformulation complexity.
• October 2035: All remaining product categories, including those with the longest transition periods (such as certain encapsulated fragrances), must achieve full compliance. By this date, intentionally added microplastics in all cosmetic and personal care products sold in the EU will effectively be banned.

The EU restriction is expected to prevent the release of approximately 500,000 tonnes of microplastics into the environment over 20 years. It is already having a global ripple effect, as multinational brands reformulate products for EU compliance and apply those formulations worldwide. However, consumers in countries without similar regulation — including the United States, where no federal restriction on microplastics in leave-on cosmetics exists — must take personal responsibility for checking their products.

How to Read Ingredient Labels for Hidden Microplastics

Identifying microplastics on cosmetic labels is challenging because they rarely appear as “microplastics” or “plastic.” Instead, they are listed by their chemical or polymer names, which can be difficult for consumers to recognize. Here is a practical guide:

Red Flag Prefixes

Any ingredient beginning with “Poly-” should raise your awareness. While not all “poly-” ingredients are problematic (polysaccharides, for example, are natural), the prefix is the single most reliable indicator of a synthetic polymer. Common examples include Polyethylene, Polypropylene, Polyurethane, Polyester, Polyamide, Polystyrene, and Polyacrylate.

Acrylate-Based Polymers

Ingredients containing “acrylate” or “methacrylate” are almost always synthetic polymers. Common examples include Acrylates Copolymer, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Ethyl Methacrylate, and Methyl Methacrylate Crosspolymer. These are extensively used in nail polishes, hair sprays, and long-wear makeup.

Silicone-Based Polymers

Ingredients ending in “-cone”, “-conol”, or “-siloxane” are silicone polymers. Dimethicone, Cyclomethicone, Cyclopentasiloxane, and Amodimethicone are among the most common. The classification of silicones as “microplastics” is debated — the EU restriction includes some but not all silicones — but many environmental and health advocates recommend avoiding them.

Other Names to Watch

Additional synthetic polymers commonly found in cosmetics include Carbomer (polyacrylic acid), PEG compounds (polyethylene glycol derivatives), VP/VA Copolymer (vinylpyrrolidone/vinyl acetate copolymer), and Styrene/Acrylates Copolymer. A comprehensive list from the Plastic Soup Foundation's Beat the Microbead campaign identifies over 500 different synthetic polymer ingredients used in cosmetics.

How the MicroPlastics App Scans Your Cosmetic Products

Memorizing hundreds of chemical names is unrealistic for most consumers. That is exactly why we built the MicroPlastics app. Here is how it simplifies the process of identifying microplastics in your cosmetics:

• Instant Barcode Scanning: Point your phone's camera at any product barcode, and the app immediately cross-references it against our database of over 100,000 products. Within seconds, you receive a clear microplastic risk score for that specific product.

Clean Beauty Alternatives: What to Use Instead

The good news is that the clean beauty movement has produced a growing number of high-quality products that perform just as well — or better — than their microplastic-laden counterparts. Here are practical alternatives for each product category:

Exfoliants

Replace plastic microbead scrubs with products that use natural exfoliants such as jojoba beads, ground walnut shell, rice bran, bamboo powder, or fruit enzymes (papain from papaya, bromelain from pineapple). Chemical exfoliants containing AHA (glycolic acid, lactic acid) or BHA (salicylic acid) provide effective exfoliation without any particles at all.

Moisturizers and Serums

Seek products that use plant-based emollients and emulsifiers instead of synthetic polymers. Shea butter, jojoba oil, squalane (derived from olives or sugarcane), hyaluronic acid (which, despite sounding synthetic, is a naturally occurring molecule), and glycerin are all effective alternatives. Look for certifications like COSMOS Organic, NATRUE, or EWG Verified, which restrict or prohibit synthetic polymers.

Foundations and Makeup

Mineral makeup brands that use zinc oxide, titanium dioxide, iron oxides, and mica as their primary ingredients are generally free of synthetic polymers. Brands committed to clean formulations use kaolin clay, tapioca starch, and silica as alternatives to nylon and PMMA for texture and opacity.

Sunscreen

Mineral (physical) sunscreens that use zinc oxide or titanium dioxide as their active ingredients are less likely to contain synthetic polymers compared to chemical sunscreens. However, always check the inactive ingredients as well, since some mineral sunscreens still use acrylate copolymers for texture. The best options explicitly state “reef-safe” and “microplastic-free” on their packaging.

Hair Care

Replace silicone-based conditioners with products that use natural oils (argan, coconut, avocado) and plant-derived conditioning agents like cetyl alcohol (from coconut or palm) and behentrimonium methosulfate (a gentle, biodegradable conditioning agent). Solid shampoo and conditioner bars often have simpler, cleaner ingredient lists and dramatically reduce plastic packaging waste as well.

Toothpaste

Choose toothpastes that use baking soda, calcium carbonate, or hydrated silica as their abrasive agents. Many natural toothpaste brands have eliminated all synthetic polymers from their formulations. Toothpaste tablets are an emerging alternative that typically have very short, clean ingredient lists.

5 Actionable Steps to Eliminate Microplastics From Your Beauty Routine

1. Audit your current products. Start by scanning the products you use daily with the MicroPlastics app. Focus on the products that stay on your skin the longest — moisturizers, foundations, sunscreens, and serums — since these provide the most prolonged exposure.
2. Prioritize leave-on products. If you cannot replace everything at once, prioritize leave-on products over rinse-off products. A moisturizer that sits on your face for 12 hours poses a greater personal exposure risk than a face wash that contacts your skin for 30 seconds.
3. Learn the key red flags. You do not need to memorize 500 ingredients. Just remember: “Poly-” prefixes, “-acrylate” suffixes, “-cone” endings, and “Nylon” cover the vast majority of synthetic polymers in cosmetics.
4. Choose certified clean brands. Look for third-party certifications like COSMOS, NATRUE, EWG Verified, or the Plastic Soup Foundation's “Zero Plastic Inside” logo. These certifications verify that products are free from intentionally added microplastics.
5. Spread awareness. Share what you learn with friends and family. The Plastic Soup Foundation found that consumer pressure is the single most effective driver of reformulation. When enough people demand microplastic-free products, brands respond.

The Bottom Line

The 87% statistic is not an abstract number. It represents the overwhelming majority of cosmetic products that millions of people apply to their skin every single day. Microplastics in cosmetics are not just an environmental issue — they are a personal health issue. With mounting evidence linking synthetic polymer exposure to endocrine disruption, inflammation, and cardiovascular risk, the case for switching to cleaner products has never been stronger.

The regulatory landscape is shifting, with the EU leading the way toward comprehensive bans. But regulation moves slowly, and enforcement timelines stretch to 2035. You do not have to wait a decade to protect yourself. By learning to read ingredient labels, choosing certified clean alternatives, and using tools like the MicroPlastics app to make informed purchasing decisions, you can dramatically reduce your exposure starting today.
