Science
Mechanism of Action
The fermentation process facilitates the breakdown of Calendula officinalis flower cell walls, significantly increasing the bioavailability of its beneficial compounds. The resulting filtrate is rich in a complex blend of plant-derived fragments and fermentation byproducts, including amino acids, peptides, organic acids (such as lactic acid), enzymes, and antioxidants. These components work synergistically to fortify the skin barrier, mitigate irritation, foster a stable skin microbiome, and provide humectant properties for superior hydration. The ingredient also contributes to maintaining an optimal skin pH, encourages cellular renewal, and defends against free radicals, thereby bolstering overall skin resilience and offering protection from oxidative stress and environmental damage. Furthermore, the presence of calendula flavonoids confers anti-inflammatory benefits and stimulates skin cell regeneration. The fermentation also generates secondary metabolites that support a healthier surface environment, improve comfort tolerance, and micro-sizes compounds for uniform distribution and reduced potential for irritation.

Key findings
- 01 A related Lactobacillus Ferment Lysate Filtrate at a 5% concentration demonstrated a 47% reduction in skin redness in an in-vivo study with 5 participants, indicating notable soothing and anti-irritant potential.
- 02 Lactobacillus extracts have been shown to stimulate beta-defensin production in skin cells in a dose-dependent manner, supporting skin's natural defenses.
- 03 Topical compositions containing Lactobacillus plantarum extract, applied regularly over six to eight weeks, reduced the incidence of both inflamed and non-inflamed acne lesions and decreased skin sensitivity.
- 04 Calendula extract, at concentrations of 3%, 5%, and 7%, exhibited beneficial effects on wound healing and provided soothing properties in albino rat models.
- 05 Calendula cream, applied topically at 20% or 30% w/w, led to a significant decrease in TNF-α and suppression of COX-2 in rats, confirming its anti-inflammatory efficacy.

Dusting Analysis
There is no available data to suggest that LACTOBACILLUS/CALENDULA OFFICINALIS FLOWER EXTRACT FERMENT FILTRATE is commonly 'dusted' or included at sub-efficacious concentrations in formulations.
The Formula
Formulation
Stability
For optimal texture and stability, and to prevent contamination, ferment products should be stored away from heat and direct sunlight, with caps securely closed. The Calendula Officinalis Flower Extract component generally maintains stability within a pH range of 4.5 to 6.5.
Safety
Safety Profile
The CIR Expert Panel has deemed Lactobacillus Ferment and related filtrates safe for cosmetic use, with reported concentrations up to 5.6% for Lactobacillus Ferment in face and neck products. Calendula Officinalis Extract and its derivatives are also recognized as safe in cosmetics, demonstrating no irritating, sensitizing, or photosensitizing effects in animal or clinical trials, though mild ocular irritation is a noted possibility. The combined ferment filtrate is generally considered safe for topical application and well-tolerated across most skin types.
