Postbiotics are metabolites, substances produced by bacteria during substrate metabolism. They come from skin microbiome bacteria and differ from probiotics (live bacteria) and prebiotics (substrates nourishing bacteria) by their nature: they are stable bioactive molecules directly usable in cosmetic formulation.
In cosmetics, postbiotics are increasingly used for their scientifically documented properties. Their use at 1.5% in our anti-aging eye contour care is based on data associating this concentration with documented support of the following properties.
Postbiotics are linked, according to available data, to documented soothing properties, support of skin hydration, and visible improvement in skin texture over time. They also support mechanisms involved in maintaining skin structure, linked to visible reduction of fine lines around the eyes.
Adding postbiotics to a formula is linked, according to available data, to preserving skin comfort and supporting hydration comfort, particularly relevant for the peri-ocular area, naturally thinner and more sensitive.
Their tolerance profile is documented as suitable for all skin types, including sensitive and reactive skin.
In summary, biotechnological origin metabolites documented for their soothing, hydrating, and skin appearance-supporting properties, suitable for the peri-ocular area.
