The Marine Ferment of Pseudalteromonas: Biotechnology in the Service of the Skin

A Microorganism from the Far North

In the depths of Greenland’s icy waters, where light barely penetrates and temperatures hover around 2°C, lives a marine bacterium of the Pseudalteromonas sp. genus.Discovered during a scientific expedition in Arctic waters, this strain has developed exceptional resistance and regeneration mechanisms to survive extreme conditions of pressure, cold, and limited nutrients.

Inspired by this natural resilience, biotechnological research has succeeded in isolating and fermenting this bacterium under controlled conditions, with no impact on marine ecosystems.The result is a 100% naturally derived marine biotechnological active, produced through laboratory fermentation of non-modified strains, following a sustainable process that respects biodiversity.This approach allows us to preserve the oceans while capturing the adaptive power of living organisms.

A Composition Rich in Natural Active Molecules

The fermentation of Pseudalteromonas produces proteoglycans and exopolysaccharides (EPS) — complex biomimetic molecules. These compounds form a natural protective film on the skin’s surface, strengthening the barrier function and preventing water loss.They also stimulate cellular regeneration mechanisms and promote dermo-epidermal cohesion, essential for skin density, suppleness, and radiance.

In vitro tests have shown a +118% increase in cellular adhesion at the epidermal level and +155% at the dermal level, indicating a significant improvement in skin integrity.The ferment also boosts collagen type I and III synthesis (up to +193% for type III), as well as elastin (+128%) and hyaluronic acid (+114%) production — key components of skin structure and elasticity.These effects result in visibly firmer, smoother, and more hydrated skin, even under stressful environmental conditions.

Regenerated and Protected Skin

Beyond structural regeneration, the marine ferment exerts a global anti-aging effect.Tests have shown a +293% increase in type III collagen synthesis after 10 days of application, and a +166% increase in heparan sulfate, a key marker of skin hydration.It also helps protect the skin from blue light exposure — a known cause of premature aging — by reducing MMP1 metalloproteinase expression (responsible for collagen degradation) by 53–64%.

Clinical tests conducted on a cream containing 2% of this active confirmed these results: +150% hydration after 7 days, +71% firmness after 28 days, up to 66% reduction in wrinkle depth and 51% reduction in wrinkle volume, along with a +75% increase in hydration and +55% boost in radiance. These outcomes confirm the restructuring, smoothing, and moisturizing power of this ferment — as effective as an intensive professional treatment.

Integrated into Artean Skincare Treatments

At Artean Skincare, this marine ferment is at the heart of the Youthful Glow Serum and the Rich Regenerating Cream formulas. In the serum, it works synergistically with green algae and Centella asiatica extracts to stimulate regeneration and reveal the skin’s natural glow. In the cream, it strengthens the skin’s structure alongside organic shea butter and soothing botanical extracts to restore lasting comfort and suppleness.Both treatments were clinically tested in vivo on 20 volunteers for 28 to 56 days, demonstrating visible improvement in skin texture, firmness, and radiance — with perfect tolerance. The Rich Regenerating Cream was also honored with an Excellence Award at the European Natural Beauty Awards, recognizing the performance of a natural formula combining scientific efficacy and sensory pleasure.

The Alliance of Science and Natural Beauty

The Pseudalteromonas ferment embodies the philosophy of Artean Skincare:an innovation born from green biotechnology, respectful of oceans and marine life;a proven efficacy, measurable on the skin and supported by rigorous scientific studies;and a unique sensory experience, where texture, purity, and performance merge to reveal the living beauty of the skin. It is the perfect example of science serving nature — and nature serving the skin.
