Today, more consumers than ever are choosing to opt for a sustainable beauty routine. Issues such as climate change, animal cruelty, and ocean pollution have impacted the way beauty brands formulate and market their products, evidenced by the increasing number of companies with B-Corp certifications, Leaping Bunny certifications, and climate pledges. But because sustainability is increasingly commodified, how does one ensure that the products they're shopping are truly eco-friendly? Furthermore, in a society where large corporations produce a majority of the world's pollution, is it possible to make a difference as an individual?

According to sustainable beauty expert Kristen Arnett, auditing your beauty routine can contribute to the greater good. "These are micro-decisions that we can make as consumers," she explains. "I can see how a consumer might say, 'Why would I bother?' Part of why you bother is because there are companies that do care, that are making a difference, and when you choose them and involve yourself in sustainability, you can help move the needle towards more sustainable corporate practices."

Living Sustainably

First, Piper admits that can feel overwhelming to try combatting big issues like animal cruelty, plastic pollution, and human rights all at once, saying that there's no such thing as a perfectly sustainable beauty routine. Instead, what's important is that customers stay mindful and do their best.

She and Arnett also advise against a complete overhaul of your existing beauty routine. They note that throwing away all your half-empty or unused beauty products is wasteful, so you should instead finish what you own before buying anything else. Only once you've finished everything in front of you should you invest in something new—sustainable or not.

Once you're ready for a refresh, Arnett and Piper urge consumers to opt for eco-friendly products, though they warn users to proceed with caution when reading labels.

"There are no reliable, standardized certifications out there that make a product 'sustainable,'" says Piper, adding that while the Federal Trade Commission recently cracked down on some of the terminology among large businesses, much of the faux eco-friendly marketing terminology (often known as "greenwashing") still goes unregulated.

However, there are still simple ways to make your routine more sustainable. Piper recommends multi-use products, such as pigments that can be used on the lips, eyes, cheeks, or liners that can be used on both the eyes and brows. Arnett adds that multi-use products not only generate less waste, but also decrease clutter, save money, and simplify one's routine.

Sustainable Ingredients

Many products claim to be sustainable but, as aforementioned, these claims often go unchecked. To examine these claims more closely, Arnett and Piper say to turn to the ingredients.

"Take a moment to really investigate," suggests Arnett. "Does this company just rely on imagery that makes you feel better? Like a leaf, or a farm, or a dew drop. Turn the package around and look at the ingredients."

Piper agrees, adding that there are certain third-party certifications customers can rely on. "I would recommend looking for more of those tried and true certifications like the PETA bunny, the Leaping Bunny, the Fair Trade symbol, and the vegan symbol," she says. "Those all have a lot of monitoring that goes into them, and they're also expensive to acquire for companies."

However, she says to also look at the parent companies of your go-to brands, noting that while particular brands may not test on animals, they're owned by larger organizations that test on animals, source their ingredients unsustainably, or have unethical manufacturing practices. Arnett adds, "I don't think anything in the aisles of any mass market department drug store is sustainable."

Greenwashing also exists with regards to how companies source their ingredients. Arnett says that while plastic-neutral and carbon-neutral designations are better than nothing, they're still as meaningful as regenerative, plastic-negative, and carbon-negative designations.

Sustainable Packaging

While there are many recyclable packaging options on the market, Arnett recommends prioritizing refillable options above all else, explaining that during the mid-20th century, most compacts were made to be refilled. During our conversation, she showed off her personal compact, which was beautifully, intricately designed. She explained that she refills it with pigments from multiple brands, making it easier than ever for her to take her collections of cosmetic staples on the go.

When you can't get a refillable option, though, Piper recommends finding products with little to no packaging like loose bar soaps. "I place emphasis on the least amount of packaging possible," she says, "And if there has to be packaging, I want that packaging to be compostable, reusable, or, at the very least, recyclable." For example, she prefers glass bottles and jars, which can be reused, over plastic packaging. She especially cautions against mixed material packaging (such as a pump, which is made from glass, plastic, and metal), noting, "Those are notoriously difficult to recycle in a traditional system."

When it comes to compostable packaging, Arnett says to pay attention to how long it takes for the packaging to compost. For instance, she says that most compostable materials take around 300 years to decompose, which does little to mitigate the impact of pollution in the short term.
