Science
Mechanism of Action
Functions through multiple pathways: suppresses tyrosinase enzyme activity and downregulates MITF transcription factor to reduce melanin synthesis, while simultaneously neutralizing UV-generated reactive oxygen species and blocking MMP-1 and MMP-3 enzymes that degrade collagen matrix
Research
Clinical Evidence
Medium confidence1%
Key findings
- 01 Acanthoic acid at 100 μM concentration significantly inhibited α-MSH-induced melanogenesis in B16F10 melanoma cells
- 02 Extract concentrations of 0.1-1.0% reduced ROS levels and inhibited collagenase expression in UVB-exposed human skin fibroblasts
Transparency
Dusting Analysis
Effective concentrations start at 0.1% based on clinical data, making concentrations below 0.05% likely insufficient for meaningful skin benefits
