What it is
A filtrate obtained after fermenting the root of the mayapple plant (Podophyllum peltatum) with Saccharomyces yeast. The fermentation is believed to enhance the bioavailability of the plant's natural compounds.
How it works
The fermentation process may produce peptides, amino acids, and antioxidants that can help neutralize free radicals on the skin. It may also support the skin's natural barrier function by providing conditioning nutrients.
Pros
Antioxidant potential
The fermentation process may create antioxidants that help protect skin from environmental stressors like pollution and UV damage.
Gentle conditioning
This ingredient is generally well-tolerated and can provide soothing and conditioning benefits without irritation.
Cons and cautions
Limited evidence
Most research is lab-based; there are few human studies confirming its effectiveness in skincare products.
Safety concerns with source plant
Mayapple root contains compounds that are toxic if ingested, so the ingredient must be processed carefully to ensure safety in cosmetics.
Best for

Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at typical concentrations. However, due to the presence of podophyllotoxin in the source plant, manufacturers must ensure the fermentation process reduces any toxic compounds to safe levels.
Research notes
Early research suggests antioxidant and skin-conditioning benefits, but most evidence comes from in vitro studies. More clinical trials on human skin are needed to confirm efficacy.
