BACILLUS/PRUNUS YEDOENSIS FLOWER EXTRACT/GLYCERIN FERMENT FILTRATE.

Valuable / HUMECTANT, SKIN CONDITIONING - MISCELLANEOUS, SKIN PROTECTING

A bio-optimized botanical ferment derived from Japanese Cherry Blossoms, engineered to enhance the bioavailability of natural polyphenols. This precision filtrate serves as a multi-functional active that targets inflammation while providing deep humectancy for a more resilient skin barrier.

Soothing agent Humectant Anti-inflammatory Skin conditioning

Science

The fermentation process utilizes Bacillus species to enzymatically cleave complex botanical structures into smaller, more penetrative metabolites. These bio-available molecules suppress pro-inflammatory signaling (inhibiting NO and PGE2) and block histamine release, while the fermentation byproduct creates a reservoir of natural moisturizing factors (NMF) and sugars to improve skin texture and hydration.

Key findings

  1. 01 In vivo testing demonstrated that a 3.0% concentration significantly mitigated erythema induced by 3.0% Sodium Lauryl Sulfate (SLS) over a 10-day application period.
  2. 02 In vitro analysis confirms anti-allergic properties via the suppression of mast cell degranulation and the inhibition of specific inflammatory mediators (Nitric Oxide and Prostaglandin E2).

Because it is an exotic botanical ferment, many brands use it at sub-clinical levels (below 2.0%) for marketing claims. To achieve the documented anti-inflammatory and soothing effects, a minimum threshold of 2.0% is required.

Stability

The filtrate is highly stable in water-based systems; however, it is heat-sensitive and must be incorporated during the cooling phase (under 40°C) to prevent the degradation of fermented metabolites.
