Science
Mechanism of Action
It utilizes a concentrated profile of phenolic compounds, including caffeic and ferulic acids, to neutralize oxidative species and inhibit pro-inflammatory cytokines. Additionally, it exerts antimicrobial pressure on specific pathogens like P. acnes and Malassezia while enhancing the skin's natural moisture barrier through improved water retention.

Key findings
- 01 Ethanolic extracts demonstrated a significant IC50 value of 284.5 µg/mL in antioxidant DPPH assays, confirming moderate free-radical scavenging capacity.
- 02 In vitro analysis revealed tyrosinase inhibition at an IC50 of 0.505 mg/mL, indicating efficacy for brightening and managing hyperpigmentation.
- 03 Demonstrated broad-spectrum antimicrobial activity against Propionibacterium acnes and Staphylococcus aureus, supporting its use in blemish-control formulations.
Transparency
Dusting Analysis
Due to its complex phytochemical profile, visible benefits for antioxidant protection and soothing are often cited at low levels, but concentrations below 0.028% are unlikely to provide the therapeutic antimicrobial or brightening effects seen in research.
