Aspergillus/Camellia Sinensis Leaf Ferment Extract

Aspergillus/Camellia Sinensis Leaf Ferment Extract is created by fermenting green or white tea leaves using Aspergillus, a type of fungus commonly used in fermentation processes. This controlled fermentation breaks down the tea's natural compounds, potentially making them smaller and more bioavailable for the skin.The resulting extract retains the antioxidant polyphenols from tea whilst gaining antimicrobial properties from the fermentation process itself. It functions as a multi-tasking ingredient that aims to protect skin from environmental stressors and support a balanced skin microbiome.

Fermentation increases the bioavailability of tea's active compounds by breaking complex molecules into smaller, more easily absorbed forms. This process also generates new bioactive metabolites from the Aspergillus fermentation itself, which may enhance the antimicrobial profile beyond what unfermented tea alone offers.Once applied to skin, the polyphenols act as free radical scavengers, whilst the antimicrobial compounds work on the skin surface to help maintain a balanced microbiome. These mechanisms work alongside the skin's natural defence systems rather than disrupting them.

This ingredient works well in serums, essences, and lightweight moisturisers where it can be absorbed efficiently. It pairs well with other antioxidants and can be used twice daily as part of your regular routine. There is no evidence of photosensitivity, so it can be incorporated into both morning and evening skincare. Allow 2–4 weeks of consistent use to observe any effects on skin texture or clarity.

Generally well-tolerated by most skin types. Those with sensitivity to fermented ingredients or tea should patch-test first, though adverse reactions are uncommon.
