Science
Mechanism of Action
The extract's primary bioactive, Brazilin, undergoes oxidation into Brazilein to neutralize reactive oxygen species (ROS). It preserves the skin's structural matrix by inhibiting matrix metalloproteinases (MMP-1 and MMP-3), which prevents collagen breakdown, and suppresses inflammatory signaling through the JAK-STAT pathway. Additionally, it exhibits antimicrobial activity by disrupting the growth and lipase production of Propionibacterium acnes.
Research
Clinical Evidence
Medium confidence2%
Key findings
- 01 In vitro analysis on human dermal fibroblasts confirmed that 0.1-5% concentrations protect against blue light-induced cellular senescence and collagen degradation.
- 02 In vivo studies demonstrated significant reduction in inflammatory angiogenic responses and potent free radical scavenging (DPPH and NO radicals).

Dusting Analysis
This ingredient is frequently included at trace levels (under 0.1%) solely to achieve a natural pink or red hue in formulations. While effective as a colorant at these levels, it requires at least 0.1% to provide the biological antioxidant and blue light protection benefits reported in clinical data.
The Formula
Formulation
Stability
Extremely pH-sensitive; it shifts from yellow (<pH 6) to deep red (pH 6-7) to purple (>pH 7). It is prone to oxidation when exposed to light and air, requiring airless packaging or stabilization.
