Science
Mechanism of Action
The fermentation process significantly boosts the bioavailability of key nutrients within sea buckthorn oil, including amino acids, peptides, vitamins, and a broad spectrum of antioxidants. Lactobacillus ferments specifically contribute to enhanced skin hydration, robust skin barrier function, anti-inflammatory responses, and the vital balance of the skin's microflora, while supporting cellular renewal. Sea buckthorn oil itself is profoundly rich in antioxidants (Vitamins C, E, carotenoids, flavonoids), essential fatty acids, and sterols. These components collectively stimulate skin regeneration, provide soothing and moisturizing effects, mitigate UV-induced damage, and encourage collagen synthesis for visibly plumper skin. Overall, this ferment filtrate functions as a potent antioxidant, skin conditioning agent, and protective barrier.

Formulation
Stability
No specific optimal pH range or explicit stability notes were identified for this exact ingredient, though fermentation processes are inherently pH-controlled. Formulators should be aware that the high carotenoid content from sea buckthorn oil may impart an orange color, which could influence the final aesthetic of the product, especially if used undiluted.
Safety
Safety Profile
The CIR Expert Panel has concluded that related Lactobacillus Ferment ingredients and similar Saccharomyces/Hippophae Rhamnoides Fruit Ferment Filtrate are safe for use in cosmetics, with no significant side effects or irritations reported. Related Lactobacillus Ferment is utilized in face and neck products at concentrations up to 5.6%. Formulators are advised that some Lactobacillus Ferment derivatives may exhibit a skin lightening effect, requiring careful consideration in product development to prevent unintended depigmentation.
