Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk

Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A filtrate from the fermentation of safflower seed oil by the yeast Pseudozyma epicola. It contains lipids, amino acids, and other bioactive molecules produced during fermentation.
How it works
The fermentation process breaks down safflower oil into smaller, more skin-compatible molecules. These molecules can help calm inflammatory signals in the skin, support the growth of beneficial skin cells, and reinforce the skin's moisture barrier by providing lipids that mimic the skin's natural oils.
Pros
Gentle soothing
Helps calm redness and irritation without harsh chemicals, making it a good choice for sensitive or compromised skin.
Barrier-friendly
Provides lipids that mimic the skin's natural oils, supporting a healthy moisture barrier and reducing water loss.
Cons and cautions
Limited evidence
Most research is from the ingredient supplier or lab studies; large-scale human trials are still limited.
Not a standalone solution
Works best as part of a broader soothing or barrier-repair routine, not as a single cure-all.
Best for
- People with sensitive or reactive skin
- Those looking for a gentle barrier-supporting ingredient
Use caution if
- Individuals with known yeast allergies (rare)
