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.

    Best serum for acne aging skin. Doesn’t dry out my skin but exfoliates and keeps it clear.

    I purchased this as an alternative to the retinol serum I was using because I'm trying to conceive. Things I absolutely love about this serum:

    1. It's delicate. You can use it morning and night.

    2. It's safe during pregnancy.

    3. It absorbs quickly. This serum has a different texture than the others (i.e. Marina, Calypso), and you can easily layer other products without becoming oily.

    4. It works! I used this twice a day for two weeks now and my skin tone is so much more even and clearer, and just overall healthier!

    I was surprised after browsing Earth Harbor's Instagram and not seeing this gem highlighted more! It's so underrated and a must try!

    I absolutely adore putting this serum on every morning. Not only does it help buffer my skin from the ravages of blue light, but it smells divine, the texture is smooth and silky, and it leaves a very delicate feeling of coolness on the surface of my skin, which soothes my irritated skin from the dry/high altitude conditions of my home. Love, love love!
