Science
Mechanism of Action
SYZYGIUM POLYANTHUM LEAF POWDER exerts its effects through several biological pathways. Rich in phenolic compounds, flavonoids, and other antioxidants like caffeic and gallic acid, it actively neutralizes free radicals, thereby protecting skin cells from oxidative stress. Its anti-inflammatory action may involve inhibiting NFκB and decreasing pro-inflammatory cytokines such as TNF-α and IL-1β. The ingredient also demonstrates broad-spectrum antimicrobial activity against various bacteria and fungi. Furthermore, it inhibits tyrosinase, the enzyme crucial for melanin production, which helps reduce the appearance of dark spots and promote a more even skin tone.

Stability
The active antimicrobial compounds within Syzygium polyanthum extract exhibit robust stability across a wide pH range (pH 3-11) and various temperatures (up to 80°C). Color stability is also noted between pH 4-10. However, some specific bioactive components may be sensitive to degradation at elevated temperatures.
Safety
Safety Profile
General toxicity evaluations reported no adverse effects following extended administration. An extract demonstrated low toxicity in Artemia salina with an LC50 of 75.85 mg/mL. In vitro tests on B16 melanoma cells indicated high cell viability even at concentrations up to 200 μg/mL, suggesting minimal cytotoxicity. Specific cosmetic safety assessments by CIR, SCCS, or FDA are currently unavailable.
