Ingredient Spotlight: The Marine Extracts in Our Sea Foam Cleanser

At Marèn, we believe the ocean holds some of the most potent ingredients for clean, healthy skin. Our Sea Foam Cleanser is carefully formulated around three powerhouse marine extracts—seaweed, brown algae (kelp), and red algae—to deliver deep hydration, antioxidant protection, and gentle purification. In today’s spotlight, we’ll explore where these extracts come from, what they do for your skin, and why they’re central to our commitment to purity.

1. What Are Marine Extracts?

Marine extracts are bioactive compounds harvested from sea plants. Rich in vitamins, minerals, and unique polysaccharides, they offer benefits that land-based botanicals simply can’t match.

  • Seaweed (Macroalgae): Yields a cocktail of vitamins A, C, E, and B-complex, plus sterols that soothe irritation.
  • Brown Algae (Kelp): A natural source of iodine, polyphenols, and fucoidans—potent antioxidants that defend against environmental stressors
  • Red Algae: Packs polysaccharides like carrageenan, which form a moisture-locking film on the skin.

Each extract is sustainably wild-harvested, then processed via cold-filtration: no high heat, no harsh chemicals, no synthetic preservatives. This method preserves the full spectrum of actives, ensuring maximum efficacy in every bottle.

2. Deep Dive on Benefits

Benefit Source Action on Skin
Hydration Boost Brown Algae Polysaccharides attract and hold moisture at the surface, plumping fine lines.
Antioxidant Defense Red Algae Neutralizes free radicals to help prevent premature aging.
Calming & Soothing Seaweed Natural sterols reduce redness and sensitivity.
Mineral Enrichment All Three Delivers magnesium, calcium, and potassium to strengthen barrier function.

Together, these extracts create a balanced formula that cleanses effectively without stripping your skin’s natural moisture or pH.

3. Our Formulation Philosophy

  1. Cold-Infusion Extraction: We steep hand-harvested seaweed and algae in purified water at low temperatures (<25 °C) to gently draw out vitamins and minerals without degrading them.
  2. Plant-Derived Surfactants: Mild, sulfate-free foaming agents derived from coconut and sugar ensure a gentle cleanse that lifts impurities but leaves your skin feeling soft.
  3. pH-Balanced Finish: Tuned to around 5.5, our Sea Foam Cleanser respects your skin’s natural acidity, supporting the microbiome and barrier health.
  4. No Fillers or Synthetic Fragrances: Every ingredient serves a purpose. You won’t find any unnecessary dyes, silicones, or artificial scents—just pure, skin-loving actives.

4. How to Use for Best Results

  1. Morning & Evening: Use twice daily for a truly fresh canvas.
  2. Dispense: Pump a nickel-sized amount into damp hands.
  3. Massage: Gently work into a fine foam in circular motions—focus on the T-zone if you’re prone to oiliness.
  4. Rinse: Wash away with lukewarm water, then pat dry.
  5. Layer Next: Follow with Marèn Dew Serum and Tide Cream for a complete clean-beauty ritual.

Whether you have oily, combination, or sensitive skin, the Sea Foam Cleanser adapts to your needs—balancing excess oil, soothing redness, and prepping your skin for hydration.

5. Meet the Ocean in a Bottle

Our commitment to purity extends beyond formulation. We partner with coastal communities that practice regenerative harvesting, ensuring the sea bed remains healthy and teeming with life. Plus, our packaging is fully recyclable, and we’re actively exploring refill programs to minimize waste.
