Unveiling the Role of Microplastics in Cosmetics
Defining Microplastics in Cosmetics
Microplastics refer to tiny plastic particles less than 5mm in size that are intentionally added to cosmetics and personal care products. They are present in items like facial cleansers, toothpaste, makeup, and more. Common types of microplastics used include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), and nylon.
The Functions of Microplastics in Cosmetic Formulations
Microplastics serve key functions in cosmetics:
- Texture: They help create smooth, soft textures and a pleasant skin feel.
- Stability: Microplastics bind ingredients together for an even distribution and longer shelf life.
- Exfoliation: Some microplastics like PE act as micro-exfoliants to remove dead skin cells.
However, there are rising concerns over their environmental impact once washed down the drain.
Microplastics and Microbeads: A Closer Look
Microbeads are a type of microplastic consisting of smooth, tiny spheres less than 1mm wide. They were a popular exfoliant additive but environmental groups raised awareness over their harm to marine life when flushed into waterways. Many countries have now banned microbeads in rinse-off cosmetics.
The Emergence of Microplastic-Free Cosmetics
In light of microplastic pollution concerns, many cosmetic companies now offer microplastic-free alternatives with natural exfoliants like salt crystals, bamboo powder, or fruit enzymes. Consumers increasingly demand sustainable products to protect ocean ecosystems. However, microplastics still persist in some makeup, hair, skin and dental care items. Further policy change and consumer action may be needed to phase them out entirely.
Which cosmetics contain microplastics?
The Plastic Soup Foundation's study of over 7,000 cosmetic products found that a staggering 87% contained microplastics. Major brands like L'Oréal Paris, Garnier, Nivea, Gillette, Oral-B, and Head & Shoulders were all found to have microplastics in their products.
Some of the most common sources of microplastics in cosmetics include:
- Exfoliating face and body scrubs
- Toothpastes
- Shampoos and conditioners
- Shaving creams
- Sunscreens
- Makeup products like foundations, concealers, powders, lipsticks and glosses
Microplastics like polyethylene and polypropylene are frequently added to cosmetics as:
- Exfoliants - to scrub away dead skin cells
- Thickeners - to change the texture of creams and lotions
- Emulsifiers - to bind ingredients together
- Moisturizers - to help products glide onto skin
- Absorbents - to soak up excess oils
When these products are rinsed off or washed away, the microplastics end up passing through water treatment plants and polluting rivers, lakes, and oceans around the world. The tiny size of microplastics also allows them to easily enter natural food chains, working their way up to bigger fish, birds, and mammals over time.
Are microplastics bad in skincare?
After you wash your face, or rinse off the lather from your body, or even take off your makeup, you might not know it but at one point you were removing microplastics from your skin. The additives and chemicals found in microplastics found in certain products are known to cause certain health problems.
Microplastics are tiny pieces of plastic less than 5 mm in size. They are commonly added to personal care products like facial cleansers, body washes, toothpaste and makeup to exfoliate, absorb oil, and alter viscosity.
Recent studies have shown that these microplastics can penetrate deep into our skin and enter our bloodstream. The health impacts are still being researched but early evidence links microplastic exposure to inflammation, oxidative stress, and even cancer.
Some specific concerns around microplastics in skincare include:
- Bioaccumulation - chemicals build up in our bodies over time
- Hormone disruption - can mimic hormones like estrogen
- Oxidative stress - leads to premature aging
- Inflammation - linked to acne, eczema and skin irritation
Given these potential risks, many consumers are now seeking out skincare and cosmetics without microplastics. Brands like [Company] offer microplastic-free alternatives to keep your skin healthy while avoiding this modern toxin.
Checking your skincare routine and switching to more natural products is an easy way to limit microplastic exposure for yourself and the environment. Small changes can lead to better health outcomes down the road.
Are microplastics banned in cosmetics?
The Microbead-Free Waters Act of 2015 prohibits the manufacturing, packaging, and distribution of rinse-off cosmetics containing plastic microbeads in the United States. This law applies to products that are both cosmetics and over-the-counter (OTC) drugs, such as toothpastes.
Specifically, the act bans:
- The manufacturing or introduction into interstate commerce of rinse-off cosmetics containing intentionally-added plastic microbeads.
- The packaging or distribution of rinse-off cosmetics containing plastic microbeads.
This ban helps reduce the amount of microplastics entering waterways from cosmetic products. However, other types of microplastics are still allowed in cosmetics and personal care products in the US.
The Microbead-Free Waters Act was an important first step, but more can be done to limit exposure to microplastics from cosmetics and reduce their impact on the environment. Some ideas include:
- Expanding the ban to cover more types of microplastics beyond just the plastic microbeads.
- Requiring products to be labeled if they contain microplastics.
- Providing incentives for companies to develop microplastic-free alternatives.
- Investing in more research on the health and environmental risks of microplastics.
While the current ban has limitations, it demonstrates growing recognition of the microplastic problem and the political will to address it. Continued advocacy and education on this issue could drive more protective legislation in the future.

Are microplastics found in 90% of cosmetics?
A recent report from the Environmental Working Group (EWG) found that almost 90% of cosmetics products from leading brands contain microplastic particles.
The report analyzed over 250 beauty and personal care products from brands like L'Oreal, Neutrogena, and CoverGirl. It found microplastics in:
- 93% of products with synthetic fragrances
- 82% of lip products with colorants
- 96% of eye and face makeup
Microplastics are tiny plastic particles less than 5 mm in size that can come from:
- Microbeads intentionally added to products
- Larger plastic beads that break down over time
- Synthetic polymers that shed microfibers
The health and environmental risks from microplastics are still being researched, but early studies show they can:
- Absorb toxins and penetrate human cells
- Pollute waterways and harm marine life when washed down drains
- Never fully biodegrade and accumulate up the food chain
To avoid exposure, check ingredient lists for common microplastic sources like polyethylene, polypropylene, and PET. Or look for labels confirming no microplastics.
As awareness grows, more brands are pledging to remove microplastics from their formulas. But regulatory action may be needed to eliminate this unseen ingredient from the over 90% of cosmetics that still contain it.
Review of Microplastics in Cosmetics: Health Risks and Concerns
Microplastics in cosmetics have become an increasing concern due to potential health risks. Recent scientific studies and expert opinions shed light on how microplastics may interact with skin, penetrate beyond the skin surface, accumulate in the body over time, and disrupt normal biological function.
Skin Absorption and Potential Irritation
- Multiple studies demonstrate microplastics can penetrate into living skin tissue in lab models. One study found polyethylene microplastics accumulated in all layers of the epidermis and upper dermis.
- Microplastics may physically irritate skin. Their small size and sharp edges could cause inflammation and sensitivity reactions, especially in those with skin conditions.
- Cosmetic formulas containing microplastics have displayed cytotoxicity - killing skin cells. This cell damage could impair skin barrier function.
Systemic Exposure Risks: Beyond the Skin
- Evidence shows microplastics can enter systemic circulation after skin application. Particles likely translocate via skin appendages like hair follicles and sweat glands.
- Once entering circulation, microplastics distribute throughout bodily tissues. Studies have detected particles in the liver, lungs, and brain of animals exposed dermally.
- Systemic microplastic exposure introduces risk of inflammatory, oxidative, and toxic effects far beyond the initial skin contact site.
Long-Term Health Implications of Microplastic Accumulation
- The human body cannot effectively eliminate microplastics. Particles accumulate over repeated exposures from continued product use.
- Build-up of microplastics may cause endocrine disruption, reproductive toxicity, organ damage, and cancer according to emerging research.
- More longitudinal studies on bioaccumulation and related health outcomes must be conducted to confirm consequences of long-term microplastic exposures.
Expert Opinions on Microplastic Safety in Cosmetics
- Toxicologists argue cosmetic producers must substantiate microplastic ingredient safety given migration ability into skin and systemic circulation.
- Public health experts advocate for more stringent regulation of microplastics in personal care products until further research establishes definitive safety.
- Some dermatologists contend cosmetic microplastics pose negligible risk as skin likely eliminates the particles without absorption. This view remains controversial given contrary evidence.
In summary, existing data sound alarms about microplastic health hazards - potentially impacting skin, internal organs, hormones, and disease processes. While some contend cosmetic microplastics are safe, numerous experts argue further study is urgently needed to conclusively determine risks versus benefits. Until then, consumers may opt to avoid these controversial ingredients.
