Science
Mechanism of Action
Through fermentation by Aspergillus and Lactobacillus, large botanical molecules are biotransformed into smaller, highly bioavailable nutrients. Rice fermentation generates kojic-like metabolites and amino acids that inhibit tyrosinase activity to reduce hyperpigmentation, while the fermentation of ginger root maximizes the potency of gingerols and shogaols to neutralize oxidative stress and soothe inflammation.

Key findings
- 01 In manufacturer testing, concentrations between 2-5% showed measurable inhibition of melanin production and enhanced hydration via improved peptide bioavailability.
- 02 An independent user trial with 120 participants reported a 99% satisfaction rate regarding skin smoothness and hydration after 28 days of consistent application.

Dusting Analysis
Because 'ferment filtrates' sound premium, brands often include them at negligible levels (below 0.5%) for marketing claims. However, clinical data suggests a minimum of 2.0% is required to effectively inhibit tyrosinase and provide significant barrier support.
The Formula
Formulation
Stability
The filtrate is highly stable in aqueous formulas but is heat-sensitive; it must be incorporated during the cool-down phase of production to protect the delicate probiotic-derived nutrients.
