Science
Mechanism of Action
This ferment oil filtrate operates through several mechanisms: it acts as an antioxidant, effectively halting oxygen-promoted reactions and safeguarding the skin against oxidative stress and deterioration. It significantly improves skin condition by enhancing elasticity, hydration, and the formation of the cornfield envelope, thereby reinforcing the skin barrier against external stressors. Its components demonstrate anti-inflammatory properties, reducing reactive oxygen species and nitrite ion levels, which translates to a visible decrease in redness and irritation. As a probiotic ingredient, it modulates the skin surface microbiome by balancing flora and inhibiting detrimental bacteria, proving beneficial for conditions like acne and rosacea. Furthermore, it supports anti-aging by promoting collagen synthesis, inhibiting enzymes like hyaluronidase and elastase, and accelerating cell renewal. It also functions as a humectant, optimizing moisture absorption and balancing skin's water and oil levels, while contributing to skin brightening by potentially reducing hyperpigmentation and dark spots.

Key findings
- 01 Lactobacillus Ferment, a key component, was deemed non-irritating and non-sensitizing in HRIPTs with 50-51 subjects when tested at 4-10%.
- 02 Lactobacillus Ferment Lysate Filtrate, another integral component, demonstrated non-irritating and non-sensitizing properties in HRIPTs with 50 subjects.
- 03 A trade mixture featuring fermented Lacticaseibacillus rhamnosus and Lactobacillus paracasei significantly reduced skin redness and improved sensitive skin symptoms in 52 patients after 30 days of twice-daily use.
- 04 5% Lactobacillus Ferment Lysate Filtrate achieved a 47% reduction in redness in a small in-vivo study (n=5), indicative of its soothing capabilities.
- 05 5% Lactobacillus Ferment exhibited anti-acne efficacy, showing both antimicrobial and anti-inflammatory benefits, leading to a faster reduction in acne lesion size and redness compared to salicylic acid.
- 06 1% Lactobacillus Ferment effectively reduced skin sensitivity.

Safety
Safety Profile
The CIR Expert Panel confirmed the safety of Lactobacillus Ferment ingredients (including Lactobacillus Ferment Lysate Filtrate) in cosmetics. The maximum reported concentration for Lactobacillus Ferment is 5.6% in face and neck products. It's crucial to note that the active components are byproducts of bacterial fermentation, not live bacteria. Formulators should be mindful that skin lightening is considered a drug effect, and products should not induce skin depigmentation. No GHS classification or toxicity data (oral, dermal, inhalation) were determined for similar 'Kluyveromyces/Lactobacillus/X Oil Ferment Filtrate' ingredients.
