Lactobacillus/Houttuynia Cordata Leaf Extract Ferment Filtrate

This ingredient is a fermented filtrate derived from Houttuynia cordata leaf extract, processed using Lactobacillus fermentation. Houttuynia cordata is a traditional Asian plant known for its use in herbal preparations. The fermentation process breaks down plant compounds into smaller, potentially more bioavailable molecules, which can enhance skin penetration and efficacy.In skincare formulations, it functions primarily as a skin conditioning agent, intended to support the skin's natural moisture balance and overall comfort.

Fermentation by Lactobacillus breaks down the plant cell walls and complex molecules in Houttuynia cordata leaf extract, creating smaller molecular fragments. This process can enhance skin penetration and bioavailability of the active compounds within the plant material.Once in the skin, these bioactive molecules are thought to interact with skin cells to support moisture retention, reduce inflammation, and provide antioxidant protection. The exact mechanisms are not fully characterised, but fermented botanical extracts generally work by delivering plant-derived compounds that support skin …

This ingredient is typically found in serums, essences, and hydrating toners. Apply to clean skin before heavier creams or oils to allow the fermented extract to absorb fully. It can be used alongside other skincare actives, though patch testing is sensible if you have sensitive skin, as fermented extracts can occasionally trigger sensitivity in some individuals.

Generally well-tolerated, though fermented ingredients can occasionally cause sensitivity in prone individuals. Those with histamine sensitivity or sensitivity to fermented foods should patch test first.
