What Is Lactobacillus/Collagen Ferment Filtrate?
Lactobacillus/Collagen Ferment Filtrate is a liquid derived from the fermentation of collagen using beneficial lactobacillus bacteria. The fermentation process breaks down collagen into smaller molecular fragments and produces bioactive compounds, creating a filtrate that can be incorporated into skincare formulations.
This ingredient functions primarily as a humectant, meaning it helps draw moisture into the skin and support hydration. The fermented nature of the ingredient may also introduce amino acids and peptides that could contribute to skin conditioning, though the extent of these benefits depends on the fermentation process and concentration used.
Benefits for Your Skin
How It Works
The ingredient works as a humectant by attracting and binding water molecules to the skin's surface and upper layers. This increases skin hydration and can temporarily improve skin plumpness and smoothness.
The fermentation process also creates peptides and amino acids that may support skin condition. Additionally, fermented ingredients can contribute to overall skin conditioning, though research on the specific mechanisms of this fermented collagen filtrate remains limited.
Clinical Evidence & References
Evidence specific to Lactobacillus/Collagen Ferment Filtrate is sparse in published research. The ingredient is based on established science around fermentation and collagen hydrolysates, which are known to provide hydration benefits, but direct clinical data on this particular ingredient blend is not widely available.
As a fermented ingredient, it likely shares some properties with other fermented skincare actives that have shown benefits for hydration and skin barrier function, though individual studies on this specific filtrate would strengthen confidence in its efficacy claims.
How to Use
This ingredient is typically found in serums, essences and hydrating products. It works well in layered routines and can be applied after cleansing and before heavier creams. It mixes well with other humectants and hydrating ingredients. No special precautions are needed for most users, though patch testing is always sensible when introducing new products.
