Rated 4.9 stars
204 Reviews
From the wildcrafted Sea Samphire plant, Samphire is a proven botanical that acts like retinol. Except this green queen is naturally non-irritating, non-photosensitizing, and overflowing with phyto-Vitamin C— giving your skin the rare opportunity to rejuvenate itself both day and night through biomimicry. Her blurring + hydrating formula is also a physical barrier against blue light emitted from electronic devices (ie. cellphones and computers). She vows to give your skin royal treatment in this digital age!

A guilt-free fountain of youthful glow, Samphire not only reigns as a safe retinol-like alternative and blue light blocker, but also leads as a sustainable one since it is a rapidly renewable succulent plant. Samphire is also pregnancy-friendly, specifically designed for sensitive skin, and eliminates the need to gradually build up a tolerance to retinol. Dive right in!

Sea Samphire helps blur imperfections like fine lines & wrinkles while helping skin regain a smooth, unclogged finish. With proven benefits comparable to retinol, Samphire is the plant-derived alternative to a standard 1% retinol serum. It also has high levels of Vitamin C and other essential antioxidants that help safeguard skin against free radicals known to cause premature aging.

Banana Fruit Juice, Red Algae, Ocean MSM, and Persian Lilac Extract holistically combine to protect skin from blue light damage and help reverse effects of artificial light on skin— all while perfecting overall appearance of skin through superabundant bio-actives.

Coconut Water, Vegan Hyaluronic Acid, Fermented Beet Sodium Lactate, and Vegetable Glycerin give skin a strengthened, bouncy feeling through synergistic hydration and moisture retention properties.


Shake well before use. Separation is natural and expected. Apply 2-4 drops to clean skin and massage in as a leave-on treatment. A mild cooling sensation is normal, particularly for the first few uses. Use daily for amplified results.

Customize: Add a few drops of Samphire to any Earth Harbor treatment or moisturizer for a phyto-retinol booster shot.

Store at room temperature and out of direct sunlight.

    So far, so good!

    I only just started using Samphire as part of my nighttime routine. I like the feel of the product- it absorbs quickly and isn’t sticky. I later other moisturizing EH product on top. My skin has definitely aged prematurely due to years of using drying products for adult acne, pregnancies and sun damage. I’m hoping that Samphire helps to gently soften some of my lines and wrinkles over time. We shall see!

    It hard to explain but this serum is perfect my skin can get really oily and when I used this I was worried it would make me more oily. But it just right. it so hard to explain it just smooth I guess you could say and fresh love it. I also see a difference in fine lines on forehead it really hard to find the right type of skincare for me I'm so happy I found you guys. I hope to be able to try other products soon like the new cleanser. Thank you for making this product. Plus I like the ingredients are safe 🙂❤
