Prebiotics are substances that nourish and support resident bacteria of the skin microbiome. They differ from probiotics (live bacteria) and postbiotics (bacterial metabolites) by acting upstream, providing a substrate favorable to the growth and activity of beneficial microorganisms on the skin surface.
The skin microbiome is the ecosystem of microorganisms colonizing the skin surface. Its balance is documented in scientific literature as a factor linked to skin comfort. When this balance is disturbed, skin tolerance may decrease and discomfort sensations increase.
In cosmetics, prebiotics are linked, according to available data, to supporting skin comfort and preserving hydration comfort against external factors. They are also associated with documented soothing properties that help visibly reduce redness and discomfort sensations.
Associated with maintaining skin microbiome balance, prebiotics contribute to more comfortable, supple, and radiant-looking skin over time. Their tolerance profile is suitable for all skin types, including sensitive or reactive skin that particularly benefits from microbiome support.
In summary, natural-origin actives documented for their contribution to skin microbiome support, skin comfort, and soothing properties, suitable for all skin types.
