Our refills are the same Earth Harbor gems, sealed with aluminum tops and completely plastic-free! While many brands use pouches for refills, our glass bottles with aluminum tops have a lower ecological footprint based on sustainability-focused research. Both materials are widely and easily recycled, making refilling truly waste-free!

Packaging
Our glass containers are 100% recyclable, and closures use 50% PCR plastic (varies by availability). Boxes, inserts, and shipping materials are compostable, made with FSC-certified/recycled paper and soy-based ink. Every product also has a plastic-free option and zero-waste refills.
How to recycle
For a zero-waste choice, get a refill. Each comes in a glass bottle with an aluminum lid. Swap your old closure onto the new bottle, then recycle the empty glass and lid! If not refilling, wash, remove the label, and recycle the glass. Take apart closures and check local recycling guidelines—small pieces (like closure elements and label backing) can be recycled through PACT Collective or be discarded. All boxes and shipping materials can be composted, reused, or recycled.

I gave up trying new products on my skin because anything would make my rosacea worse. But my skin was dry and needed a thicker moisturizer. Im so glad I took a chance on this one, I now have 3 products from this brand and cant wait to try more!
