Our refills are the same Earth Harbor gems, sealed with aluminum tops and completely plastic-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.

This is a great moisturizer and skin treatment. I love that a glass jar is used and that I can get a refill. My skin is moist and my fine wrinkles diminished.

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!

I used to have dry patches on my face every single time I would do my make up, no matter how much I moisturize until I started using this. It’s totally changed my routine.

My face has taken a turn after 40 and gets a red cast with weird, almost flaky cheeks and random tiny pustules. I check ingredients over extremely thoroughly and had tried plenty but it always felt like less was more, so I stuck with my toner and serum stick. I was tired of my cheeks drying out without something hydrating and protective this cold, dry winter, so I took a chance on siren silk and nymph nectar. I was able to test several products at my local grocer and loved how soft both made the back of my hand without the strong, off putting mermaid milk smell or tackier finish. The nymph nectar was working great but still left my cheeks a little red and flaky, but with a spritz of rose water toner, siren silk followed by nymph nectar-voila! I love that siren silk has virtually zero smell and absorbs instantly, so I just add a little nymph nectar on top to nourish, seal and protect my face day and night. It doesn’t build up or clog pores and it feels incredibly beneficial. I am gaining more confidence again and don’t wonder if I should conceal or mask myself with this power duo. My main concern was effectively hydrating my skin and eliminating redness and so far after a few days, so good! <3
