Science
Mechanism of Action
The fermentation process breaks down plant proteins into small-molecule peptides, amino acids, and tyrosinase-inhibiting arbutin for deep penetration. These metabolites work synergistically to suppress melanin synthesis, stimulate the production of essential ceramides, and neutralize inflammatory cytokines like TNF-α to soothe the dermal environment.

Key findings
- 01 Clinical trials observed a 32% improvement in skin radiance and a measurable decrease in hyperpigmentation over 8 weeks at a 2.0% concentration.
- 02 Application of 0.5%–2.0% demonstrated a 45% increase in ceramide synthesis and a 30% reduction in transepidermal water loss (TEWL).
- 03 In vivo testing at 1.0% showed improved structural integrity of the dermal-epidermal junction (DEJ) and increased epidermal thickness.

Dusting Analysis
Because this ingredient is often marketed as a high-performance 'ferment,' brands frequently include it at trace levels (under 0.1%) for marketing claims. Efficacy for barrier repair and brightening requires a minimum concentration of 0.5%.
