Science
Mechanism of Action
Pseudoalteromonas Exopolysaccharides function by binding and retaining moisture in the skin, similar to hyaluronic acid, attributed to their richness in glucuronic acid. They actively stimulate the synthesis of critical skin proteins, specifically type I and IV collagen and elastin, which promotes cellular regeneration and contributes to a smoother skin surface. Beyond hydration, this ingredient forms a protective film on the skin to shield against cold weather and redness, while also demonstrating the ability to regulate sebum production, reduce shininess, and minimize pore size, potentially by modulating the Melanocortin 5 receptor.

Key findings
- 01 Increased skin hydration by 14.8% in cold weather (as Antarcticine, a trade name for diluted Pseudoalteromonas Ferment Extract).
- 02 Decreased the depth of wrinkles around the eyes by 44% (as Antarcticine, a trade name for diluted Pseudoalteromonas Ferment Extract).
- 03 Delivers immediate and long-lasting skin hydration, reduces skin roughness, and attenuates wrinkles.
- 04 Demonstrated a significant reduction in fine lines and crow's feet with continued use over 28 days, improved hydration by enhancing water retention and preventing water loss, promoted skin regeneration, and boosted collagen and elastin production for reduced wrinkle formation and firmer eyelids.

Formulation
Stability
Pseudoalteromonas Exopolysaccharides are ideally produced and demonstrate biological activity in a neutral to slightly acidic pH range of 5.5 to 7.5. For stability in finished cosmetic formulations, particularly in aqueous solutions, the use of approved preservatives is recommended to mitigate microbial contamination.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) panel has assessed Pseudoalteromonas Exopolysaccharides (EPS) as nontoxic and safe for use in cosmetic formulations. While specific FDA drug approval status is not assigned to cosmetic ingredients, its safety is supported by rigorous evaluations required by EU regulations (N°1223/2009), which cover aspects such as acute toxicity, irritation, skin sensitization, and repeated dose toxicity.
