Science
Mechanism of Action
This ingredient operates primarily as a powerful humectant, leveraging its polysaccharide content to attract and bind water, thereby profoundly boosting skin hydration. It forms a subtle, protective layer on the skin's surface, which effectively minimizes transepidermal water loss (TEWL) and locks in essential moisture. Furthermore, Alteromonas Ferment Filtrate actively stimulates the skin's intrinsic production of key components like hyaluronic acid, lipids, and filaggrin, all critical for maintaining optimal hydration and barrier integrity. Its anti-inflammatory properties offer soothing relief, diminishing redness and irritation, while its antioxidant capabilities defend against free radical damage. Uniquely, it also provides an anti-pollution shield by creating a biomimetic mesh that reduces particulate matter adhesion and offers protection against heavy metals and hydrocarbons, fostering a healthy skin microbiome. Lastly, by enhancing collagen production, it contributes to anti-aging effects, smoothing the appearance of fine lines and wrinkles.

Key findings
- 01 A clinical study demonstrated a 30% increase in skin hydration after four weeks of daily use, involving 50 participants.
- 02 In an in-vivo test on 15 volunteers, skin hydration was rapidly improved and sustained for at least 6 hours (using an unspecified concentration, trade name Exo-H).
- 03 In-vitro studies on fibroblast cell cultures showed a significant boost in collagen production by up to 67%.
- 04 Further in-vitro research confirmed increased collagen synthesis in human dermal fibroblast cells at concentrations of 0.1% and 0.2%.
- 05 A cream formulation containing 0.02% of the ingredient, alongside others, exhibited anti-aging benefits, including redefined facial contours and improved skin, after 56 days of use in 33 women.

The Formula
Formulation
Stability
This ingredient maintains stability within a pH range of 4.5 to 7.0. Efficacy may diminish below pH 4.5 due to potential breakdown of glycoproteins and polysaccharides, and above pH 7.0, the exopolysaccharide film-forming structure could destabilize, impacting viscosity. For optimal integration, incorporate into the water phase at temperatures below 40°C. Storage should be in airless or opaque packaging, away from excessive heat, light, and oxidation.
Conflicts
- High pH environments (exceeding 7.0)
- Strong oxidizing agents
- Live probiotic formulations
- Potentially irritating when combined with strong exfoliants or drying agents, especially for sensitive skin
- Other fermented ingredients (may collectively increase acidity and exacerbate sensitivity)
Safety
Safety Profile
Generally regarded as safe and well-tolerated across diverse skin types, including sensitive skin, with a low overall risk profile. However, in rare instances, mild irritation or allergic reactions could occur; a preliminary patch test is advised, particularly for individuals with sensitive skin. It is not recommended for those with known allergies to marine or bacterial extracts. While the Cosmetic Ingredient Review (CIR) has evaluated other fermented ingredients, Alteromonas Ferment Filtrate itself has not undergone a specific CIR review according to available data. The FDA regulates cosmetic ingredients through general manufacturing practices rather than pre-market approval.
