Sustainability
Running Responsibly
We are committed to a long-term, science-based approach to sustainability. We know it's time to think bigger about the impact our products and their full life cycle have on people and the planet.
Percentage of recycled content
-
This metric refers to the percentage of material by weight that has been recycled from post- or pre-consumer sources.
Number of plastic bottles

With help from our suppliers, we calculate the number of plastic bottles used to make a size medium of each product.
Climate action
We are using sound science to address climate change and align our efforts across every level of our business to reduce carbon emissions. This includes product designs, materialization, manufacturing, and our global supply chain.
