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.

    Works wonders for my skin

    This combo, together with a few other Earth Harbor product, are just what my face needs, especially regarding those fine lines one gets in their 30s.

    Love my siren silk

    I love the feel of siren silk. It's thick and creamy and yet feels light on my skin. It keeps my skin hydrated when I visit the mainland and things are less humid than at home. It helps to keep my psoriasis in check and flair ups to a minimum. Thank you!!
