Lactobacillus … Ferment Filtrate

This ingredient is a fermentation filtrate derived from Laminaria digitata, a brown seaweed, that has been processed using beneficial microorganisms including Lactobacillus, Lactococcus, Leuconostoc and Saccharomyces species. The fermentation process breaks down the seaweed's complex compounds into smaller, more bioavailable molecules.The resulting filtrate functions primarily as a skin conditioner, helping to improve skin texture and maintain moisture. Fermented plant extracts are increasingly used in skincare because fermentation can enhance the stability and efficacy of botanical ingredi…

Fermented seaweed filtrate works primarily through humectant and conditioning mechanisms. The fermentation process generates smaller molecular weight compounds, including amino acids and oligosaccharides, which can penetrate the skin more readily than whole plant material.Seaweed naturally contains polysaccharides and minerals that support skin hydration and barrier function. The filtrate form allows these beneficial components to interact with skin's surface more effectively, helping to maintain moisture and improve tactile smoothness.

This ingredient is typically found in serums, essences and moisturisers at concentrations that suggest it works best as part of a layered routine. Use it as a hydrating or conditioning step before heavier creams. It suits most formulation types and can be used daily as part of your regular skincare regimen.

Generally well-tolerated as fermentation can reduce irritation potential. Individuals with sensitivity to fermented products or seaweed should patch-test first.
