    Sensitive or compromised skin, urban skin exposed to pollution, and routines focused on calming over correcting.

    The full picture

    Alteromonas is a genus of marine bacteria whose fermented byproducts contain a profile of polysaccharides, amino acids, and minerals beneficial to skin. As an extract it functions as a humectant-plus-soothing active that pairs well with peptides and antioxidants. Found in ISDINCEUTICS Age Contour as part of the brand's dermo-cosmetic firming and barrier-support story.

    Evidence

    A marine ferment used for hydration and soothing. Most evidence is supplier and formulation-level rather than independent trials.
