From Microbeads to Microplastics | The Rise of Plastic Free Beauty

While consumers have grown more aware of microbeads (primary microplastics) in cosmetics, the wider issue of secondary microplastics in beauty products is often overlooked.

Unlike visible plastic packaging waste, secondary microplastics are almost invisible and harder to trace, but no less harmful. Defined as synthetic polymers under 5mm in size, they are still widely used in cosmetics as they are inexpensive and can help to improve texture, extend shelf life, and provide a particular finish. These particles go by names such as polyethylene (PE), polypropylene (PP), and polymethyl methacrylate (PMMA), often listed in small print under ‘film-formers’ or ‘binders’.

But as awareness increases and scrutiny intensifies, the demand for cosmetics without microplastics is pushing brands and formulators to create microplastic free cosmetics, which means identifying new, more sustainable materials that perform just as well, without adding to plastic pollution.

Formulation is no longer just about feel or function; it’s about accountability. This shift opens the door to ingredient innovation, new supplier partnerships, and deeper transparency. So, as we mark Plastic Free Beauty Day, it’s time to rethink the way cosmetics are formulated, packaged, and brought to market.

Why are microplastics used in cosmetics?

Microplastics are chosen for specific functional reasons, for example, they can enhance viscosity, stabilise emulsions, or forming films that improve water resistance and wear. For formulators, these materials have long been reliable tools.

The problem isn’t their performance, but their permanence. Once rinsed off, these particles bypass most wastewater filters and accumulate in aquatic ecosystems, where they persist for decades and can harm marine life.

Today, plant-based polymers, biodegradable film formers, and naturally derived powders are gaining popularity.

How to identify and avoid microplastics in cosmetics

Spotting microplastics on a label isn’t always straightforward. Ingredients such as acrylates copolymer, PEG compounds, or nylon-12 often fall under the category.

Tools such as ‘Beat the Microbead’ or INCI analysis platforms can help brands and consumers flag potential concerns. Understanding this is crucial when aiming to create microplastic free makeup or cosmetics without microplastics that are truly clean, and not just marketed that way.

Are microbeads banned worldwide?

The global conversation around plastic in cosmetics began with microbeads, which were commonly used as exfoliants in face washes and scrubs. Today, many countries, including America, the UK, Canada, and several in the EU, have laws banning them from rinse-off products.

But is the microbeads ban worldwide? Not yet. Regulatory progress is uneven, and definitions vary. Some bans apply only to rinse-off products, while others are expanding to include leave-on formulations and additional plastic types.

For forward-thinking brands, the question isn’t just ‘Are microbeads banned?’, it’s ‘What else are we putting in our products that could soon be restricted?’.

Reformulating proactively will not only ensure compliance but build consumer trust and place your brand ahead of the curve.

Plastic free, eco-friendly skincare brands and products

As the impact of plastic in beauty becomes more visible, the demand for plastic free beauty products is pushing brands to innovate across the entire product lifecycle, from formulation to packaging.

To do this, some brands have started to embrace refillable components, compostable wraps, and glass or metal containers over single-use plastic. At the formulation level, they’re choosing biodegradable ingredients and eliminating synthetics that leave behind harmful residues.

Brands that act now to create plastic-free beauty solutions, are not only meeting consumer expectations but also helping shape regulatory and market norms.

The best natural face exfoliator for every skin type

Replacing microplastics doesn’t mean compromising on skincare performance. In fact, some of the best natural exfoliators for face offer added skin benefits along with a lower environmental impact. Some of our favourites to incorporate into skincare formulations include:

• Ground apricot stones

A classic physical exfoliant, best for oily skin types.

• Bamboo powder

Fine and effective, suitable for most skin types.

• Jojoba powder

Smooth, biodegradable, and non-abrasive, ideal for sensitive skin.

Whether you are formulating the best natural face exfoliator, body scrub, or any other products, these alternatives offer a plastic-free approach that maintain efficacy and environmental care.

O&3 Thoughts…

This is more than a trend. Consumers are looking for high-performance beauty and personal care products that don’t compromise environmental values, and formulators are beginning to act on this.

Plastic Free Beauty Day is more than a moment on the calendar; it’s a call to action. Whether you’re a brand, formulator, or consumer, your choices influence the future of the industry.

Reformulating without microplastics. Replacing single-use packaging. Rethinking what performance really means. These are the steps that lead to cleaner oceans, healthier ecosystems, and a beauty industry that aligns with the values of the next generation.
