KLUYVEROMYCES/LACTOBACILLUS/ACANTHOPANAX KOREANUM BARK/STEM OIL FERMENT FILTRATE.

Insufficient Data / ANTIOXIDANT, ASTRINGENT, SKIN CONDITIONING, SKIN PROTECTING

This advanced biotechnological ingredient is a specialized filtrate, produced through the fermentation of volatile oils derived from the bark and stems of *Acanthopanax koreanum* by a consortium of *Kluyveromyces* and *Lactobacillus* microorganisms. This precise fermentation process is engineered to enhance the bioavailability of beneficial compounds within the botanical extract, specifically increasing the concentration of phenolic compounds.

Astringent Antioxidant Skin conditioning Skin protecting

Science

Mechanism of Action

Functioning as a versatile active, this ferment filtrate exhibits astringent, antioxidant, skin conditioning, and skin protecting properties. The original *Acanthopanax koreanum* plant is naturally rich in bioactive constituents such as lignans, coumarins, triterpenes, phenolic compounds, and saponins. The microbial fermentation by *Kluyveromyces* and *Lactobacillus* is critical in amplifying these advantageous components, particularly phenolic compounds, thereby optimizing their efficacy and delivery to the skin.

Verdict

Insufficient Data

While KLUYVEROMYCES/LACTOBACILLUS/ACANTHOPANAX KOREANUM BARK/STEM OIL FERMENT FILTRATE presents promising multi-functional attributes and a low irritancy profile, the absence of specific clinical efficacy studies and detailed formulation parameters necessitates an 'insufficient-data' verdict for a comprehensive assessment.
