Science
Mechanism of Action
This ingredient operates as a sophisticated ferment filtrate, containing a spectrum of beneficial compounds including amino acids, peptides, organic acids (notably lactic acid), enzymes, and antioxidants, all liberated during its unique fermentation process. It critically supports the skin's inherent microbiome, fortifies the cutaneous barrier, and actively calms irritation. Possessing humectant qualities, it significantly improves hydration, while its antioxidant capacity provides robust defense against oxidative stress and environmental damage. The fermentation process synergistically amplifies Aloe's anti-inflammatory properties, enhances the bioavailability of its sterols and anthraquinones, stimulates collagen synthesis, and inhibits MMP-1 (matrix metalloproteinase-1) to effectively mitigate skin wrinkling. The organic acids also contribute to maintaining a healthy skin pH and facilitate gentle exfoliation.

Key findings
- 01 An Aloe vera leaf skin fermented by Lactobacillus plantarum extract (AF) at 0.3% concentration demonstrated mitochondrial activation in UVb-irradiated human skin fibroblasts, resulting in collagen production increases up to 125 ± 5.45% and MMP-1 secretion decreases down to 69.41 ± 2.63% of control levels.
- 02 An in-vivo study utilizing 5% Lactobacillus Ferment Lysate Filtrate observed a significant reduction in skin redness by 47%.
- 03 Topical application of Lactobacillus Ferment Filtrate has been shown to reduce signs of skin sensitivity, including stinging and itching, while concurrently boosting hydration and offering protective effects against pollution and oxidative stress.
- 04 Clinical investigations indicate that fermented Aloe (Lactobacillus/Aloe Barbadensis Leaf Ferment Filtrate) is 40% more effective than conventional Aloe extract in reducing skin redness induced by environmental stressors.

Stability
The ingredient demonstrates optimal stability and activity within an acidic pH range of 4.0 to 4.5, consistent with the naturally acidic environment produced by lactic acid fermentation processes.
Safety
Safety Profile
The CIR Expert Panel has determined that Lactobacillus Ferment, along with its Filtrate and Lysate forms, are safe for cosmetic use. While a maximum concentration of 1.5% is noted for Lactobacillus Ferment in makeup bases, specific data for the full ingredient is limited. For the Aloe Barbadensis component, an industry-established limit of 50 ppm or lower for anthraquinones in nonmedicinal aloe-derived material is recommended.
