Science
Mechanism of Action
This extract functions as a potent anti-inflammatory agent by inhibiting the synthesis and release of inflammatory mediators such as nitric oxide (NO), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6). Its quercetin component demonstrates inhibitory activity on COX-1 and COX-2 enzymes comparable to diclofenac. By reducing capillary permeability and improving microcirculation, it effectively aids in the absorption of edema fluid. Rich in flavonoids and phenolic acids, it provides robust antioxidant protection while stimulating fibroblast growth and collagen production to support anti-aging and tissue regeneration. Additionally, it offers emollient, astringent, and phlebotonic effects, contributing to moisturization, pore tightening, and the alleviation of conditions like couperose, hematomas, and sprains.

Stability
Formulations containing Melilotus officinalis extract exhibited stable physical characteristics (color, odor, consistency, homogeneity, and no phase separation) over a 6-month storage period at 22 ± 2 °C within a pH range of 5.15 (cream) to 7.15 (gel). A significant decrease in pH was observed after 6 months, but stability was maintained within the first 2 months. The extract's stability and activity are influenced by its various constituents, including coumarins, flavonoids, phenolic acids, vitamin C, tannins, and allantoin.
Safety
Safety Profile
Topical application of 2% Melilotus officinalis extract did not induce dermal irritation in rat studies, indicating safety at this concentration. The ingredient has a history of safe use in skincare for at least 30 years. However, broader preparations of melilot (not specifically topical skin applications at defined concentrations) have been associated with potential adverse events such as gastrointestinal complaints, allergic reactions, and photosensitivity in some studies.
