Science
Mechanism of Action
This ferment filtrate optimizes epidermal water transport by upregulating Aquaporin-3 (AQP3) expression, the skin's primary hydration channel. Simultaneously, it provides antioxidant protection through organic acids like phytic acid, inhibits α-MSH-induced melanin production to clarify skin tone, and utilizes enzymatic activity to promote the desquamation of dead keratinocytes without physical irritation.

Key findings
- 01 Clinical evaluation of a serum containing this filtrate demonstrated a 100% participant success rate in significant hydration improvement after a single application.
- 02 7-day longitudinal study showed 94% of users reported measurable improvements in skin softness and texture.

Dusting Analysis
As a 'ferment filtrate,' it is frequently included at sub-clinical levels (<0.2%) for label-claim marketing. To achieve the physiological AQP3 upregulation and brightening effects seen in clinical trials, it should be formulated near the 1-2% mark.
