Science
Mechanism of Action
The fermentation process significantly enhances the nutritional profile of Camellia Japonica Seed Oil, yielding a filtrate rich in postbiotic metabolites and free fatty acids. These compounds facilitate improved skin absorption and deliver multi-faceted benefits. Camellia Japonica Seed Oil itself actively supports anti-aging by stimulating collagen production, reducing wrinkle appearance, and enhancing skin elasticity. It also exhibits anti-inflammatory effects by moderating pro-inflammatory gene expression, deeply moisturizes by optimizing skin hydration and minimizing transepidermal water loss, and provides antioxidant defense against environmental stressors. The ferment also contributes antiseptic, fungicidal, and bactericidal properties, alongside potential skin lightening through tyrosinase inhibition.

The Formula
Formulation
Stability
While no specific pH range is available for this exact ferment, similar ferment filtrates (e.g., Saccharomyces/Barley Seed Ferment Filtrate) are known to maintain efficacy within a pH range of 5-7. The fermentation process itself is noted to improve emulsifying capacity.
Safety
Safety Profile
The CIR Expert Panel considers Lactobacillus Ferment and its filtrates safe for cosmetic use. While reported uses for Lactobacillus Ferment reach up to 5.6% in face and neck products, formulators must be aware that postbiotic metabolites from Lactobacillus can act as tyrosinase inhibitors, potentially leading to skin depigmentation. This effect is classified as a drug effect, and cosmetic applications should avoid inducing such changes. Camellia Japonica Seed Oil itself has a very low hazard rating (EWG score of 1) and is generally considered safe. No specific SCCS or FDA status for the complete ingredient was found, but Lactobacillus Ferment has extensive FDA VCRP and RLD uses.
