What Is Gluconobacter/Honey Ferment Filtrate?

Gluconobacter/Honey Ferment Filtrate is a liquid extract derived from honey that has undergone fermentation using Gluconobacter bacteria. During this process, the bacteria break down sugars and other compounds in honey, creating a filtrate rich in organic acids, amino acids, and other fermentation byproducts.

In skincare, this ingredient functions primarily as a humectant and skin conditioning agent. It works to draw moisture into the outer layers of the skin and help maintain hydration, whilst also contributing to the skin's overall comfort and suppleness.

How It Works

The fermentation process creates a range of bioactive compounds, including gluconic acid, which is gentler than some other acids used in skincare. These compounds help soften the skin and improve its ability to retain water, whilst the organic acids may also have mild exfoliating or pH-balancing properties.

As a humectant, the ingredient draws moisture from the environment and deeper skin layers into the outer epidermis. This hydrating action is thought to improve skin texture and overall comfort, particularly in dry or dehydrated skin.

Clinical Evidence & References

Evidence specifically evaluating Gluconobacter/Honey Ferment Filtrate as a standalone ingredient is limited. Most existing research focuses on honey and fermented honey extracts more broadly, which have been shown to possess antioxidant and moisturising properties in laboratory and small-scale studies.

Published clinical trials on this specific filtrate in humans are sparse, so claims about its efficacy rest largely on its known composition and traditional use of fermented honey in skincare. Further research would help clarify its effectiveness compared to other humectants and conditioners.

How to Use

This ingredient is typically found in serums, essences, and hydrating formulations at low concentrations. It works well alongside other humectants such as glycerin and hyaluronic acid, and pairs naturally with antioxidants and nourishing oils. Include it as part of your regular hydration routine, applying to damp skin to maximise its moisture-binding effect.

Safety & Precautions

Fermented honey extracts are generally well-tolerated by most skin types. Those with honey sensitivity or allergy should avoid this ingredient, though fermentation may reduce allergenic potential.
