Science
Mechanism of Action
The multifaceted action of this ferment filtrate contributes directly to optimal skin health. It actively strengthens the skin's natural barrier, calms irritation, and fosters a stable microbiome, crucial for robust skin defense. Its humectant properties enhance hydration by attracting and retaining moisture. As a potent antioxidant, it neutralizes free radicals, offering protection against environmental aggressors and oxidative stress. The meticulous fermentation process releases key beneficial compounds, including amino acids and peptides that support cellular repair, boost hydration, and improve skin resilience. Organic acids, such as lactic acid, help maintain a healthy skin pH, provide gentle exfoliation, and further enhance moisture levels. Enzymes contribute to skin renewal and barrier recovery. The Prunus mume fruit component specifically protects skin structural proteins from glycation and aids in the decomposition of Advanced Glycation End-products (AGEs), thereby reducing yellowish pigmentation and improving skin tone and firmness. It also amplifies the efficacy of other antioxidants against aging. Furthermore, the Lactobacillus ferment contributes to skin brightening by inhibiting tyrosinase activity to reduce melanin synthesis, alongside offering anti-inflammatory and skin immunity-boosting effects.

Stability
Optimal stability for the probiotic components within fermented Prunus mume by-products has been observed within a pH range of 4.0-5.0. Formulations typically avoid traditional preservatives that could compromise the integrity of beneficial microbes, often relying on other methods for product stability.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that components such as Lactobacillus Ferment Filtrate are safe for use in cosmetics. The highest reported maximum concentration of use for Lactobacillus Ferment is up to 5.6% in face and neck products. While a potential skin lightening effect was noted as a drug effect, concerns were mitigated due to its known mechanism (tyrosinase inhibition) and clinical experience; formulators are advised to prevent unwanted depigmentation. No genotoxicity or endocrine disruption was observed in relevant assays. It is important to note that a specific CIR review for the entire LACTOBACILLUS/ASPERGILLUS/PRUNUS MUME FRUIT FERMENT FILTRATE complex was not identified, though Prunus mume seed extract has been found non-toxic on skin. Data regarding inhalation toxicity for spray applications is currently insufficient.
