Saccharomyces/Hexapeptide-11 Ferment Filtrate Extract

Saccharomyces/Hexapeptide-11 Ferment Filtrate Extract is a hybrid ingredient combining a fermented yeast derivative with a synthetic hexapeptide. The fermentation process breaks down yeast cells to yield bioactive compounds, which are then combined with hexapeptide-11—a short chain of amino acids designed to mimic structural proteins in the skin.

In formulations, this ingredient functions primarily as a skin conditioning agent, helping to maintain hydration and support the skin's natural barrier function. The peptide component is included to provide signalling benefits, though the degree of penetration and efficacy depends on formulation pH, molecular weight, and vehicle.

Fermented yeast derivatives contain amino acids, vitamins, and polysaccharides that act as humectants and skin-conditioning agents, drawing moisture into the stratum corneum. The hexapeptide-11 component works through a different pathway: peptides can be recognised by skin cells as signalling molecules, potentially triggering mild structural support responses, though actual penetration into living skin layers remains variable.

Together, these components are designed to work synergistically—the fermentation byproducts provide immediate hydration and nourishment, while the peptide offers longer-term signalling support. The overall effect is typically skin conditioning and smoothing rather than dramatic transformation.

This ingredient is typically found in serums, essences, and moisturisers at concentrations that optimise hydration without irritation. Use it as part of a consistent routine rather than expecting immediate results; skin conditioning benefits tend to emerge over weeks of regular application. It pairs well with other hydrating ingredients such as glycerin or hyaluronic acid, and works in both morning and evening routines.
