ONE/SIZE is Cruelty-Free

ONE/SIZE has confirmed they do not test their products or ingredients on animals or ask others to test on their behalf. Their suppliers also do not test on animals, nor do they allow their products to be tested on animals when required by law. And finally, their products are not sold in stores in mainland China or any other country that may require animal testing.

By our standards, we would consider ONE/SIZE to be Cruelty-Free.

The following is a snippet of the response I received from ONE/SIZE when I emailed the brand to verify its cruelty-free status:

Hi Vy! Welcome to O/S Beauty. Thanks for reaching out. So happy to help answer these great questions. We do not do any testing of either or raw ingredients or products on animals. We also do not allow third parties or have third parties that are doing any testing of any sorts on animals. We also have documentation from our filler that our laboratories and suppliers do not test on animals. We are not sold in China or in any market that requires animal testing by law. Our products are vegan!

In addition, below is a screenshot of what’s currently stated on ONE/SIZE’s website about its animal testing policy:

What About China’s Animal Testing Laws?

ONE/SIZE has confirmed they do not sell their products in retail stores in mainland China; therefore, they are not required to test on animals.

As of May 1, 2021, some imported ordinary cosmetics can be exempt from animal testing under certain conditions. However, for the most part, animal testing is still legally required for most imported cosmetics in 2022.

Cruelty-Free Policies

Note that there is no legal definition for the label ‘Cruelty-Free.’ It can mean different things to different people. But Cruelty-Free is generally used to imply no animal testing. More specifically, the ingredients, formulation, or finished product are not tested on animals at any stage of product development.

At ethical elephant, we always assess a company’s cruelty-free policy using our Cruelty-Free Checklist. This ensures no animal testing was performed by the brand itself, its suppliers, and by any third parties.

Also, note that Cruelty-Free and Vegan don’t always mean the same thing.

ONE/SIZE is 100% Vegan

ONE/SIZE has confirmed all of its products are vegan and don’t contain any animal-derived ingredients or by-products.

The following is a screenshot of what’s currently stated on ONE/SIZE’s website about its vegan claims:

Vegan Policies

Similar to ‘Cruelty-Free,’ there is no standard or legal definition for the label ‘Vegan.’ But it’s usually used in the context to describe something that doesn’t contain any animal-derived ingredients or animal by-products.

Some common animal products used in cosmetics include carmine, lanolin, snail mucus, beeswax, honey, pearl or silk-derived ingredients, animal-based glycerin, keratin, and squalene.

There are plant-based and synthetic alternatives to animal-derived ingredients. But it’s sometimes difficult to know with certainty whether a product is vegan just by reading the ingredient list.

So it’s best to ask the company and manufacturers to ensure the ingredients they’ve chosen to use were from non-animal sources.

Where are ONE/SIZE’s products made?

I asked ONE/SIZE where their products are manufactured and they told me:

“ONE/SIZE products are developed and produced within the USA”

Ethical Mica Mining Policy

Mica is a mineral that’s used in cosmetics to add a shimmery effect. But the mining of natural mica has been linked to child labor and human rights violations.

Unless the company discloses its mica mining policy, we have no way of knowing whether its mica is ethically sourced without child or forced labor.

So I asked ONE/SIZE if their mica is ethically sourced without the use of child labor and they responded by stating,

“Hi Vy, welcome back to O/S. I believe we’ve spoken before so that you for all of the product questions regarding how we handle this. Yes we do ethically source all of our Mica as well as always do routine audits with each and every supplier to ensure they are compliant.”


I hope this article helped you to understand ONE/SIZE’s cruelty-free and vegan status and by choosing cruelty-free together, we can help end animal testing for cosmetics once and for all!
