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 feel like it’s my duty to share it with others how amazing this product (and company!) is. Truly, Earth Harbor’s products have changed my life. Silk Siren has strangers stopping me to compliment my 41 year old complexion. It took a month or so and then it just got better and better. I also use Nymph Nectar and Glow Juice. Like woah.
I have rosacea and none of these bother them if that is helpful to anyone.

I have been using the products for a luttle over 2 weeks now , so i cant really make an honest review on the benefit i have notifed by usung it . Unfortunately, I recieved a damaged package . I was able to salvage some of the cream , but one of the containers did open , i dont know if it was heat related , or if it’s because there is jo seal on them , but it did arrive a bit messy . Ill keep using what i salvaged, to see if the product will benefit my skin type 😊👍🏼

Best moisturizer for my aging, acne prone skin.I used Mermaid milk at AM and Siren silk at PM, but realized I need thicker moisturizer in the morning too.

This is an amazing hydrating cream that does not cause me to break out! I use it as my night cream and always wake up with such soft, hydrated skin. It's truly the best! In the summer months I use the mermaid milk for day and siren silk at night. In the winter I use siren silk more both day and night. I can definitely tell the difference with my complexion with this. 10/10
