2% Botanic BHA (from beets) is an effective salicin-rich alternative to salicylic acid that gently exfoliates and smooths skin texture.

Prebiotics & Postbiotics (from sea kelp and chicory root) promote a healthy skin microbiome and balanced complexion.

Sea Samphire is a retinol alternative herb, known as a jewel of the coast, that blurs imperfections, reduces appearance of fine line and wrinkles, and strengthens skin barrier.

Banana Fruit Juice, Ocean MSM & Beta Glucan (from mushrooms) are vitamin-rich superstars that help repair skin’s natural collagen production, maintain plumpness, and protect against blue light.

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. Give a little shake if separation occurs.

Customize: Add a few drops of Samphire to any Earth Harbor treatment or moisturizer for a clarifying & perfecting booster.

Store at room temperature and out of direct sunlight.

    As a skincare enthusiast dedicated to achieving a flawless complexion, Samphire Biotic Perfecting Serum it’s a unique gem 💎 that I’m adding to my skincare routine. 🌟

    Upon application, the serum’s lightweight texture effortlessly glides onto my skin, providing a burst of hydration and a subtle cooling sensation.

    The 2% Botanic BHA gently exfoliates, revealing a smoother and more even skin texture over time.

    I love how this serum addresses multiple skin concerns with its powerhouse ingredients.

    🔸 I love the light green color, it’s soothing and reminds me of nature and plants. 🌱

    🔸 It comes in a glass bottle with dropper, easy to use. 🔸 The scent is subtle, fresh and herbal.

    🔸 The texture is lightweight and my skin absorbs it easily.

    Love Samphire!

    Love the new formulation of Samphire! I think this is my new favorite serum! It is not as oily as the old formulation and since I avoid putting oil-based products on my acne-prone skin, it is better for me!

    I love it!

    I work for Holland & Barrett Belgium and I use this product for 6 weeks now. I can't stop feeling my skin after using it, I really love it in my day routine! I do have a question....can I use it in the morning and in the evening, or is that to much? What is best?
