Science
Mechanism of Action
The extract utilizes its primary neoflavonoid, Brazilin, to inhibit tyrosinase activity and neutralize reactive oxygen species (ROS). It acts as a biological shield by downregulating pro-inflammatory cytokines (TNF-α, IL-1β) and suppressing Matrix Metalloproteinases (MMP-2 and MMP-9) to prevent collagen fragmentation, while also upregulating antioxidant enzymes like GPX7 to mitigate UVA and blue light-induced cellular damage.

Clinical Evidence
Medium confidence1%
Key findings
- 01 Concentrations as low as 20 µg/mL demonstrate free radical scavenging comparable to L-ascorbic acid.
- 02 A 1.0% concentration provides significant antibacterial efficacy against Cutibacterium acnes.
- 03 In-vitro models show a 76.82% reduction in cytotoxicity at 25 µg/mL, confirming high cytoprotective capacity.

Dusting Analysis
Often included at very low concentrations (under 0.1%) to serve as a natural colorant or marketing 'claim' ingredient. To achieve functional antioxidant or anti-acne benefits, concentrations should meet or exceed 0.5–1.0%.
The Formula
Formulation
Stability
Thermolabile; must be incorporated during the cool-down phase below 40°C. The natural pigment is pH-sensitive, shifting from red in acidic environments to purple in alkaline conditions.
Synergies
- Sodium Phytate (chelating agent for color stability)
- L-Ascorbic Acid (antioxidant synergy)
- Niacinamide (barrier and brightening support)
Conflicts
- Strong oxidizing agents
- Alkaline environments (pH > 7.5)
- High-temperature processing (> 45°C)
Safety
Safety Profile
While not officially reviewed by the CIR, it is widely utilized in Asian pharmacopeia and recognized by the EU CosIng and FDA VCRP for skin conditioning.
