Acetobacter … Ferment Filtrate

This ingredient is a fermented extract derived from aronia melanocarpa and pyrus serotina (wild pear) fruit juices, processed using Acetobacter and Saccharomyces cultures. Fermentation breaks down the fruit compounds into smaller, potentially more bioavailable molecules whilst concentrating beneficial compounds like polyphenols.The resulting filtrate functions primarily as an antioxidant in skincare formulations, helping to neutralise free radicals that accumulate on the skin from environmental exposure such as pollution and UV radiation.

The fermentation process converts larger polyphenolic compounds in the fruit juice into smaller molecules that may penetrate the skin more effectively. These polyphenols work by donating electrons to unstable free radicals, stabilising them and preventing them from damaging skin cells and collagen.This protective mechanism is particularly relevant in urban environments and for skin exposed to regular sun exposure, where free radical accumulation is heightened.

This ingredient is typically used as part of a broader antioxidant skincare routine rather than as a standalone treatment. It works well in serums, essences, and hydrating products and can be layered with other actives. Allow it to absorb fully before applying occlusive products. For best results, use consistently as part of daily skincare, ideally in the morning when environmental protection is most needed.

This ingredient is generally well-tolerated in cosmetic products. As a fermented botanical extract, patch testing is recommended for those with known sensitivity to fruit-derived ingredients or fermented products.
