What Is Saccharomyces/Honey Ferment Filtrate?

Saccharomyces/Honey Ferment Filtrate is produced by fermenting honey using Saccharomyces (baker's yeast) and then filtering the resulting liquid. The fermentation process breaks down the honey's complex sugars and proteins into smaller, more bioavailable molecules that skin can more readily absorb.

This ingredient functions primarily as a skin conditioner, helping to improve skin feel, texture and hydration. The fermented filtrate contains amino acids, B vitamins and trace minerals that support the skin's natural moisture-binding capacity.

How It Works

During fermentation, Saccharomyces yeast breaks down honey's larger molecules into smaller peptides and amino acids. This increases the ingredient's bioavailability — essentially making the beneficial compounds in honey easier for the skin to absorb and utilise.

Once applied to skin, the filtrate deposits humectant and emollient properties that support the skin's natural moisture barrier, whilst the amino acids and vitamins contribute to skin conditioning and a smoother surface texture.

Clinical Evidence & References

Published clinical studies specifically examining Saccharomyces/Honey Ferment Filtrate are limited. However, the individual components — fermented honey, amino acids and B vitamins — have established roles in skincare formulation for hydration and conditioning.

Fermentation as a processing method is known to enhance ingredient bioavailability and preserve beneficial compounds. Real-world use suggests this ingredient is well-tolerated and contributes to improved skin feel, though rigorous comparative clinical data would strengthen confidence in specific efficacy claims.

How to Use

This ingredient is typically found in serums, essences, toners and moisturisers. Apply after cleansing and before heavier creams to allow the ferment filtrate to absorb fully. It can be used daily as part of a regular skincare routine. If combining with active ingredients like acids or vitamin C, apply this conditioning product after actives have dried to enhance hydration and minimise potential irritation.

Safety & Precautions

Generally well-tolerated across skin types. Those with honey allergies or severe yeast sensitivities should patch test first, though fermentation typically reduces allergenicity.
