What Is Paecilomyces Japonica/Caragana Sinica Root Ferment Extract Filtrate?
Paecilomyces Japonica/Caragana Sinica Root Ferment Extract Filtrate comes from the roots of the Caragana sinica shrub, a resilient plant native to East Asia. The roots are placed in a controlled tank with Paecilomyces japonica, a safe fungus known for breaking down plant material in a gentle way. Over several days the microorganism digests parts of the root, releasing skin-friendly sugars, amino acids and small peptides. Once fermentation is complete the mix is filtered so only the clear liquid packed with these nutrients remains.
Caragana roots have long featured in traditional beauty routines for their calming and moisturizing feel. Fermentation took off in modern skin care because it boosts the availability of the plant’s natural compounds without harsh chemicals. Korean and Japanese brands were early adopters of this method in the late 2000s, and global formulators soon followed.
The finished filtrate slips easily into water-based products, bringing lightweight moisture and a silky touch. You will most often spot it in hydrating essences, sheet masks, soothing serums, daily moisturizers, anti-aging creams and after-sun gels.

Comedogenic Rating
Rating: 0 / 5
This filtrate is water-based, lightweight and contains virtually no oils or waxy residues that could clog pores. The sugars, amino acids and peptides it delivers are highly soluble in water so they rinse away easily and do not sit inside follicles. For these reasons it is considered non-comedogenic.
Suitable for acne-prone or breakout-prone skin.
As with any ferment there can be slight batch-to-batch differences depending on how the raw plant material was grown or processed, but these do not typically influence pore-clogging potential.

The ingredient enjoys moderate popularity, showing up most often in Korean and Japanese hydrating toners, sheet masks and gel creams while still being relatively rare in Western lines. Brands use it when they want a gentle plant ferment that adds hydration without heaviness.
