Cutibacterium Avidum/Granulosum Ferment Extract Filtrate

Cutibacterium avidum and granulosum are naturally occurring bacteria found on human skin. This ingredient is a fermented extract and filtrate of these microorganisms, processed to remove the bacterial cells themselves and retain the beneficial compounds they produce during fermentation.In skincare formulations, it functions primarily as a skin conditioning agent and emollient, helping to soften and smooth the skin's surface. It is typically used at concentrations between 5% and 24% in finished products.

Fermented bacterial extracts contain metabolites and compounds produced by microorganisms during the fermentation process. These include amino acids, peptides, and other bioactive molecules that can interact with the skin's surface.When applied topically, these fermentation byproducts are thought to work as humectants and occlusive agents, drawing moisture into the skin and helping to seal it in. This dual action supports skin hydration and improves the overall feel and appearance of the skin texture.

This ingredient is typically incorporated into moisturisers, serums, and hydrating creams where it works alongside other humectants and emollients. No special application technique is required. Use as directed on the product packaging, usually as part of your regular moisturising step.

Generally well-tolerated by most skin types. As with any fermented ingredient, those with sensitivities to fermentation byproducts or prone to reactions may wish to patch test first.
