What it is
A fermented extract created by combining Pseudozyma epicola yeast with Camellia Japonica seed oil, then filtering the resulting liquid. The fermentation process can generate new compounds like peptides, organic acids, and enzymes that may benefit the skin.
How it works
The fermentation process breaks down the camellia oil into smaller molecules that may be more easily absorbed. The resulting filtrate contains yeast metabolites that can help support the skin's natural barrier and provide a soothing effect. It works primarily as a skin conditioner, helping to maintain moisture and comfort.
Pros
Gentle conditioning
Provides a soft, smooth feel without the heavy texture of plain oils, making it suitable for sensitive or reactive skin.
Soothing potential
The fermentation process may produce compounds that help calm redness and irritation, offering a mild soothing effect.
Cons and cautions
Limited research
There are few peer-reviewed studies on this specific ferment, so its benefits are not as well-established as more common ingredients.
Variable quality
The final ingredient's properties depend heavily on the fermentation conditions, which can differ between manufacturers.
Best for
- Those with dry or dehydrated skin looking for a gentle conditioning ingredient
- People interested in fermented skincare ingredients for their potential soothing properties
Use caution if
- Individuals with a known allergy to camellia or yeast-derived ingredients
