Science
Mechanism of Action
This ferment filtrate exerts its benefits through a multifaceted approach to skin improvement. It deeply hydrates the skin while strengthening the skin barrier. Its rich composition, derived from both carrot root (including vitamins A, C, K, and carotenoids like beta-carotene) and the fermentation process (peptides, enzymes, organic acids such as lactic acid, and polysaccharides), supports cellular renewal and provides gentle exfoliation. It acts as a natural antioxidant, combating free radicals to mitigate premature aging, and crucially helps to balance the skin's microflora and pH, fostering an optimal environment for skin regeneration and repair.

The Formula
Formulation
Stability
This ingredient presents as a lightweight, clear to slightly yellowish liquid, which facilitates easy incorporation and absorption into formulations. During its production, the fermentation of carrot juice by Lactobacillus strains typically results in a pH reduction from approximately 6.0 to a range of 4.9-5.1. While the presence of lactic acid contributes to balancing skin pH, for robust product stability, further acidification below pH 4.5 has been suggested in some contexts.
Safety
Safety Profile
The CIR Expert Panel has affirmed the safety of Lactobacillus Ferment ingredients, including filtrates, for cosmetic application, with reported usage concentrations up to 5.6% in face and neck products. This specific Lactobacillus/Carrot Root Extract Ferment Filtrate is generally considered safe for topical use, predicted to be non-cytotoxic, non-irritating, and non-sensitizing based on general Lactobacillus ferment assessments. However, individuals with existing allergies or extremely sensitive skin should exercise caution.
