Science
Mechanism of Action
The composite mechanism of action leverages the distinct properties of its fermented constituents. Grifola frondosa actively suppresses reactive oxygen species (ROS), thereby reducing oxidative stress, and mitigates inflammation by attenuating apoptosis-related proteins, inhibiting NF-κB pathways, and blocking inflammasome-mediated caspase-1 activation. Furthermore, it promotes collagen synthesis and reduces matrix metalloproteinase-1 (MMP-1) expression, contributing to anti-wrinkle and wound-healing effects. Fermented Citrus unshiu peel enhances skin moisturization by stimulating hyaluronic acid production and increasing the expression of filaggrin and SPT in keratinocytes. Carthamus tinctorius seed oil, rich in linoleic acid, aids in sebum regulation, reinforces the skin barrier, and provides emollient properties. The overall fermentation process boosts the bioavailability of beneficial compounds and may yield novel bioactive molecules, while rice seed fermentation also contributes antioxidant benefits and improved ingredient solubility.

The Formula
Formulation
Stability
While precise optimal pH and stability for the complete ferment filtrate are not specified, component data offers guidance. Monascus fermented rice extract shows stability in the pH 2-6 range, with increased absorbance at higher pH. Rice protein solubility generally increases at pH values below 3 and above 8. Safflower oil extraction processes have been optimized around pH 5.
Safety
Safety Profile
Direct CIR, SCCS, or FDA safety status for the entire multi-ferment filtrate is currently unavailable. However, its individual components have been reviewed; Carthamus Tinctorius (Safflower) Seed Oil by CIR, and Grifola frondosa extract is listed by The Good Scents Company with no GHS hazard classifications. Citrus-derived peel oils are generally considered safe in cosmetics when formulated to be non-sensitizing and non-irritating, with appropriate restrictions on 5-methoxypsoralen (5-MOP) content for leave-on products. Other ferment filtrates have shown no adverse reactions in continuous skin irritation tests, suggesting a generally favorable safety profile for this ingredient class.
