Science
Mechanism of Action
Functions primarily by inhibiting tyrosinase, the enzyme responsible for melanin production, effectively disrupting the pathway that leads to dark spots. Additionally, it acts as a scavenger of reactive oxygen species (ROS) and downregulates pro-inflammatory markers like COX-2 and PGE2 to mitigate damage caused by UVB exposure.

Clinical Evidence

Key findings
- 01 Demonstrated measurable reduction in melanin index and tyrosinase activity in herbal cream formulations.
- 02 In vitro studies at 25-100 µg/mL showed significant recovery of cell viability following ultraviolet stress.
Transparency
Dusting Analysis
As a rare botanical, it is frequently used at 'label claim' levels (below 0.1%). To achieve the tyrosinase inhibition and antioxidant recovery seen in research, it should be present at higher concentrations in a pH-stabilized formula.
The Formula
Formulation
Stability
Extremely sensitive to pH levels; bioactive anthocyanins remain stable and pigmented in acidic environments (pH 2-5) but degrade and lose efficacy in neutral or alkaline conditions (pH 7-8).
Synergies
- L-Ascorbic Acid (shared acidic pH requirement)
- Tocopherol
- Ferulic Acid
Conflicts
- Alkaline ingredients
- Strong oxidizing agents
- Direct UV exposure (requires opaque packaging)
Safety
Safety Profile
Widely consumed as a food source in Southeast Asia; topical application is considered safe and non-irritating for all skin types when formulated correctly.
