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 struggle with hyperpigmentation and this cream really lifts and brightens my skin for a more even look. The smell is amazing so I look forward to using it every night and my skin is amazingly soft in the morning when I wake up!

This was a surprise. I liked the hydration immediately but I noticed that after using every night for a week my fine lines are less, skin is smooth, and sensitive redness is much better. The results were even bettter after a month of use. The smell isn't my favorite but I wouldn't change it for a minute because of how effective it is.

I have re-ordered this delicious moisturizing cream! I use it daily, sometimes at night and also in the morning as my face just glows after application! I also found it at my local Whole Foods store and can pick it up anytime I need more! I won't go a day without using it!
