What Is Pseudozyma Epicola/Olive Fruit Oil Ferment Filtrate?
Pseudozyma Epicola/Olive Fruit Oil Ferment Filtrate is derived from olive fruit oil that has been fermented using Pseudozyma Epicola, a naturally occurring yeast. The fermentation process breaks down the oil into smaller molecular components, creating a filtrate that can be more easily absorbed into skin and incorporated into cosmetic formulations.
This ingredient functions as a skin conditioner and humectant, meaning it helps to soften the skin surface and draw moisture into the outer layers. It is also used in haircare products for similar conditioning purposes.
How It Works
Fermentation breaks down olive oil into smaller, more bioavailable components. These include polyphenols, fatty acids, and other compounds that can penetrate the skin more easily than unprocessed oil.
As a humectant, the ingredient draws water molecules from the deeper layers of the skin and the environment into the outer layer (stratum corneum), improving hydration. The conditioning action creates a smoother skin surface by coating and softening the outermost cells.
Clinical Evidence & References
Formal clinical studies specific to this fermented olive extract are limited in the published literature. However, olive oil and its bioactive components are well-established in skincare research for their moisturising and antioxidant properties.
The fermentation process is designed to enhance bioavailability and reduce the heavy feel of unprocessed oil, though direct comparative evidence for this particular fermented version is not widely available. It is a relatively niche ingredient, and further research would help clarify its specific benefits and efficacy in skincare formulations.
How to Use
This ingredient is typically found in serums, moisturisers, and conditioning treatments. It works well in layered routines and can be combined with other hydrating or nourishing ingredients. No special application technique is required; use as directed by the product instructions, generally once or twice daily depending on skin type and product type.
