Bacillus … Ferment Filtrate

This ingredient combines three components: Bacillus (a fermentation-derived microorganism), Houttuynia Cordata Leaf Extract (a plant traditionally used in Asian skincare), and Volcanic Ash Ferment Filtrate (mineral-rich volcanic material processed through fermentation). Together, they form a conditioning agent intended to support skin texture and resilience.The fermentation process breaks down the plant material and volcanic minerals into smaller, more bioavailable forms. This preparation is designed to work as a skin conditioning agent—meaning it aims to improve how skin feels and behaves …

Fermented ingredients work by breaking down larger botanical molecules into smaller peptides and bioactive compounds that skin can more readily absorb. Houttuynia Cordata is traditionally valued for its soothing properties, whilst volcanic ash minerals may provide trace elements that support skin health.The combination functions as an emollient and conditioning agent, creating a supportive environment on the skin surface rather than targeting a specific biological pathway. This makes it a gentler, multi-purpose ingredient suited to maintenance of skin comfort.

This ingredient works best as part of a complete skincare routine. It is typically found in serums, essences, and moisturisers where it can be applied to clean skin morning and evening. Layer it under heavier creams if using in a serum form, or use it as the primary moisturiser step depending on your skin's needs.

Generally well-tolerated in cosmetic formulations. Those with sensitive skin or known sensitivity to fermented ingredients should patch test first, though adverse reactions are uncommon.
