Science
Mechanism of Action
This bio-fermented complex operates via a multifaceted mechanism. Lactobacillus fermentation significantly enhances skin hydration, reinforces the epidermal barrier, and confers both anti-inflammatory and potent antioxidant properties. It actively stabilizes the skin's microflora and pH, promotes cell renewal, and contributes to a more even skin tone. Simultaneously, the Acorus calamus component provides inherent antimicrobial, anti-inflammatory, and additional antioxidant effects, effectively neutralizing free radicals, safeguarding the skin from environmental stressors, assisting in pore refinement, and overall skin toning. The controlled fermentation process is crucial for mitigating potential toxins and maintaining the delicate balance and integrity of the skin microbiome.

Stability
This ingredient is water-soluble and exhibits optimal stability within a pH range of 4.0 to 6.0, aligning with the reported pH stability of its unfermented Acorus Calamus root extract precursor. As a ferment filtrate, it also actively supports the maintenance of the skin's healthy pH balance.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Lactobacillus Ferment and its filtrates are safe for use in cosmetic formulations, with a reported maximum concentration of 5.6% in certain skin care products. Formulators should be cognizant that postbiotics derived from Lactobacillus bacteria via fermentation may exhibit tyrosinase-inhibiting activity, potentially leading to skin depigmentation if not incorporated judiciously to avoid such a drug-like effect. It is important to note that while unfermented Acorus Calamus Extract is listed by the FDA as 'PROHIBITED' for food additive use due to concerns over β-asarone content, this restriction specifically pertains to food applications and does not directly extend to cosmetic use, particularly for fermented ingredients and where β-asarone-free extracts are utilized.
