About this ingredient
Pseudoalteromonas ferment extract is obtained by culturing the marine bacterium Pseudoalteromonas. INCI: Pseudoalteromonas Ferment Extract. Its main component is an exopolysaccharide the bacterium produces to survive in cold seas. In a formula it works as a moisturizing and soothing component: it holds water, forms a protective film on skin, and is credited with a firming and repairing action. The component has studies from the developing brand, but the independent base is more modest, so it is a supporting active. Pregnancy safety. Topical use is systemically negligible, with no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, suitable for sensitive skin.
