Science
Mechanism of Action
This ingredient functions synergistically through its fermented components. The Ophiopogon japonicus root extract significantly fortifies the skin's epidermal barrier by improving cell cohesion and boosting natural moisturizing factors, thereby optimizing hydration and minimizing trans-epidermal water loss. Its humectant properties draw and retain moisture within the skin. It exhibits potent anti-inflammatory effects by modulating the MAPK signaling pathway, reducing pro-inflammatory mediators such as IL-1β, IL-6, and nitric oxide, which effectively calms redness and irritation. As a powerful antioxidant, its homoisoflavonoids and polysaccharides neutralize free radicals, safeguarding skin against oxidative stress. Furthermore, it supports cellular vitality by promoting fibroblast proliferation and enhancing natural cell metabolism, contributing to improved elasticity, firmness, and a reduction in fine lines. The Lactobacillus ferment component acts as a beneficial postbiotic, fostering a balanced skin microbiome, which helps to retain moisture and defend against environmental stressors, restoring the skin's natural bacterial equilibrium.

Key findings
- 01 Clinical investigations into oligofructans derived from Ophiopogon japonicus root (a key component) have demonstrated significant improvements in atopic dermatitis. Studies showed a reduction in flare-ups, substantial improvement in SCORAD scores (addressing erythema, pruritus, and affected body surface area), enhanced patient quality of life, and a marked decrease in relapse rates compared to placebo. It is important to note these studies specifically focused on the extract, not the complete ferment filtrate.

Similar Kluyveromyces/Lactobacillus/Root Oil Ferment Filtrate ingredients are indicated as 'not for fragrance use' or 'not for flavor use', suggesting their primary functional role is not sensorial and formulation considerations should align with their active properties.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Lactobacillus Ferment, Lactobacillus Ferment Filtrate, and similar variants are 'safe as used in cosmetics.' While this provides assurance for the Lactobacillus component, a specific CIR, SCCS, or FDA assessment for the full complex ingredient, KLUYVEROMYCES/LACTOBACILLUS/OPHIOPOGON JAPONICUS ROOT OIL FERMENT FILTRATE, is not publicly detailed. Toxicity data (Oral/Parenteral, Dermal, Inhalation) for this exact ingredient are reported as 'Not determined' by The Good Scents Company, with no associated GHS hazard statements.
