Science
Mechanism of Action
This ingredient, or its extracts, operates through several key mechanisms within the skin. It exhibits broad-spectrum antimicrobial activity against both Gram-negative and Gram-positive bacteria. Its potent antioxidant capabilities are attributed to the presence of phenolic compounds, flavonoids (reaching concentrations of 0.8% in leaf extract and 1.08% in stem extract), and scytalone, which collectively scavenge free radicals and impede lipid peroxidation. Anti-aging effects are achieved by inhibiting matrix metalloproteinase-2 (MMP-2), inducing telomerase activity, and reducing tyrosinase activity alongside melanin production for enhanced skin brightening. Furthermore, the ingredient contains alpha-amyrin, known for its anti-inflammatory properties, and actively stimulates fibroblast proliferation, crucial for tissue repair and wound healing. Osmoprotectants like proline and glycine betaine are also present, potentially supporting skin hydration and osmotic balance.

Key findings
- 01 Antimicrobial activity against a wide spectrum of Gram-negative and Gram-positive bacteria, evidenced by 13-20mm inhibition zones from an n-hexane extract.
- 02 Antioxidant activity (DPPH radical scavenging) for Suaeda maritima root extract (SMRE), with an SC50 of 0.29 mg/ml.
- 03 Antioxidant activity (inhibition of lipid peroxidation) for SMRE, with an IPC50 of 0.08 mg/ml.
- 04 SMRE inhibited matrix metalloproteinase-2 (MMP-2) by 7.24±2.17% in human skin fibroblasts.
- 05 SMRE increased telomerase activity in HeLa cells by 1.35±0.24%.
- 06 SMRE inhibited tyrosinase by 41.26±8.75% and melanin production by 22.43±6.00% in B16F10 melanoma cells.
- 07 SMRE stimulated proliferation of human skin fibroblasts by 26.58±5.91% and promoted wound healing.

Dusting Analysis
There is no specific data available to indicate that Suaeda Maritima Flower/Leaf/Stem Powder is commonly 'dusted' or used in sub-efficacious concentrations in formulations.
The Formula
Formulation
Stability
Optimal pH range for the stability of Suaeda Maritima Flower/Leaf/Stem Powder has not been specifically determined. However, its active components exhibit solubility in both aqueous and oil phases, suggesting versatility in formulation, as various solvents like hexane, methanol, ethanol, and water are effective for extraction.
Safety
Safety Profile
No specific safety assessments have been conducted by major regulatory bodies such as CIR, SCCS, or FDA for Suaeda Maritima Flower/Leaf/Stem Powder or its extracts. A critical finding from one study noted that Suaeda maritima root extract (SMRE) at a concentration of 1.0 mg/ml exhibited toxicity against human skin fibroblasts. This is particularly significant given that other studies reported beneficial effects, such as fibroblast proliferation and wound healing, at the identical 1.0 mg/ml concentration of SMRE. Conversely, SMRE showed no cytotoxicity in B16F10 melanoma cells and HeLa cells across various tested concentrations. These findings emphasize the necessity for precise concentration control and further comprehensive safety evaluation for cosmetic applications.

Verdict
Suaeda Maritima Flower/Leaf/Stem Powder presents a valuable profile for diverse skin concerns, offering antioxidant, anti-aging, antimicrobial, and wound healing benefits; however, careful formulation at optimal concentrations is imperative given reported fibroblast toxicity at 1.0 mg/ml for its root extract.
