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 serum combines the best of both worlds by blending polypeptides and hyaluronic acid, along with a whopping 20 ultra-hydrators, seaweed collagen, niacinamide, and other active ingredients, to provide a powerful, multi-benefit treatment. Unlike typical hydrating or peptide serums, it not only locks in moisture but also visibly smooths, plumps, and refreshes your skin. It gives an instant glow while working over time to promote a youthful, rejuvenated look. Its lightweight, non-sticky formula absorbs quickly without any heaviness, delivering long-lasting hydration, firming, and radiance for your healthiest, glowing skin.
Absolutely! The combination of peptides, ultra-hydrators, and niacinamide makes this serum a powerhouse for preventing dryness and dehydration. It helps lock in moisture, leaving your skin feeling hydrated and plump without any greasy residue. Plus, it helps smooth the appearance of fine lines and wrinkles, promoting a more youthful, rejuvenated complexion over time.
Apply after cleansing and toning. Use it alone for an instant hydration boost, or layer it under a moisturizer for deeper hydration and smoother skin. It’s great for both morning and night, or you can even mix a few drops with your moisturizer for added benefits.
This serum works beautifully with your favorite Earth Harbor moisturizer or a nourishing facial oil like Calypso for added hydration and smoothness. For a complete routine, layer it with a calming toner or essence like Tidal Rose Mist or Cloudburst Essence for an extra boost of hydration and balance. It also pairs well with our other serums and concentrates that focus on rejuvenation and radiance, like Marina Brightening Concentrate and Anchor Bio-Retinol Serum.

Yes! This lightweight, non-greasy formula is ideal for all skin types, including dry, oily, combination, and sensitive skin. It deeply hydrates without causing breakouts or clogging pores.
Yes! This serum absorbs quickly, leaving a smooth, hydrated finish that works great as a primer under makeup. It helps create a fresh, glowing base for foundation or BB cream.
While results can vary depending on your skin type and routine, many people notice immediate hydration and smoother skin after the first application. With continued use, you can expect to see firmer, plumper skin, and a more radiant, even tone over time.
While this serum provides intense hydration and smoothness, we recommend following up with a moisturizer for long-lasting hydration, especially if you have dry skin or live in a dry climate. However, for those with oily or combination skin, this serum can be enough on its own, but we still recommend one of our very lightweight moisturizers like Treasure Glazing Milk or Cloudburst Essence.

Perfect for mature skin
Yuka rating is excellent. I've used this for 2 weeks on my mature 63 year old female black skin. I've used Cleu de Peau and Estee Lauder, Peter Roth, Obaji and the so called medical grade products from the med spas. I'm done with all those product lines. I still use some Korean products, and am finishing those up. This is amazing product. Happy 2026
