Aquaphilus Dolomiae Ferment Filtrate

Aquaphilus Dolomiae Ferment Filtrate is derived from the fermentation of Aquaphilus dolomiae, a microorganism, which is then filtered to create a lightweight liquid ingredient. The fermentation process breaks down cellular material into smaller, more bioavailable compounds that can interact with the skin's surface.

In skincare formulations, this ingredient functions primarily as a skin conditioner and protective agent. It is typically used in modest concentrations within serums, essences and moisturisers to support the skin's natural barrier and help maintain hydration.

Fermented filtrates work by delivering amino acids, peptides and other small molecular compounds that skin recognises and can utilise. These components help support the skin's natural moisture-binding capacity and reinforce intercellular cohesion — the way skin cells hold together.

The ingredient also appears to have mild protective properties, potentially helping shield the skin from minor environmental stressors and supporting the barrier's resilience over time.

This ingredient is well-suited to layering in a multi-step routine. Apply it to clean skin before heavier creams or oils, as its lightweight nature means it absorbs quickly. There is no upper limit to daily use; it can be incorporated into both morning and evening routines without concern.
