Lactobacillus/Kelp Ferment Filtrate

Lactobacillus/Kelp Ferment Filtrate is a liquid extract created by fermenting kelp (seaweed) using beneficial Lactobacillus bacteria. The fermentation process breaks down the kelp's cellular structure, releasing smaller molecular compounds and amino acids that can more readily penetrate or condition the skin.In skincare formulations, this ingredient functions as both a skin and hair conditioner. It works to soften and smooth the skin surface whilst contributing to hydration and barrier support, making it a common addition to serums, essences, and moisturisers.

The fermentation process converts kelp's complex polysaccharides and proteins into smaller, more bioavailable compounds. These include amino acids, peptides, and vitamins that can interact with the stratum corneum (the skin's outer layer) to improve hydration and conditioning.The ingredient's humectant properties (ability to draw moisture) combined with its amino acid content means it can both absorb water from the environment and help support the skin's natural moisturising factors.

This ingredient is typically found in leave-on products such as serums, essences, and moisturisers rather than rinse-off formats. Use as directed by your product instructions—usually once or twice daily as part of your regular skincare routine. It pairs well with other hydrating and conditioning ingredients.

Generally well-tolerated across most skin types. Those with a known sensitivity to fermented ingredients or seaweed should patch-test first.
