Science
Mechanism of Action
This ingredient operates through a dual mechanism, harnessing the distinct advantages of its two primary components. Lactobacillus Ferment Filtrate actively strengthens the skin's inherent resistance to environmental stressors, contributes to cellular regeneration, and effectively stabilizes the skin's physiological pH. It exhibits natural antioxidant capabilities, neutralizing free radicals to mitigate premature aging. Furthermore, it enhances skin hydration, fortifies the skin barrier, and provides anti-inflammatory effects to soothe irritation, promoting a balanced skin microflora essential for skin health. This action involves the production of beneficial amino acids, peptides, organic acids, and enzymes crucial for repair and renewal. Concurrently, the Fermented Antler Velvet component delivers a rich profile of polypeptides, proteins, amino acids, and pivotal growth factors such as IGF-1, TGF-β, PGE2, and EGF. These biomolecules collectively stimulate tissue repair, accelerate wound healing, minimize scarring, optimize collagen distribution, and significantly enhance skin cell proliferation, providing comprehensive anti-inflammatory and rejuvenating effects.

Dusting Analysis
Insufficient data specifically addresses 'dusting' practices for this combined ingredient. However, clinical efficacy has been observed at concentrations as low as 1% for sensitivity reduction, indicating lower concentrations may still provide benefits.
The Formula
Formulation
Stability
The Lactobacillus Ferment component exhibits optimal stability within a pH range of 4.0-5.0. The fermentation process itself naturally leads to a lowered, more acidic pH in the culture.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Lactobacillus Ferment and related filtrates safe for use in cosmetics. The highest reported maximum concentration of use for Lactobacillus Ferment is 5.6% in face and neck products. Formulators should be aware of a potential skin lightening effect due to tyrosinase inhibition and avoid use in a manner that causes depigmentation. Studies reported no genotoxicity or phototoxicity. While generally considered safe and non-toxic, a minimal risk of allergic reaction for highly sensitive individuals exists.
