Science
Mechanism of Action
It functions via a dual-action pathway: first, by neutralizing oxidative stress through its rich polyphenolic profile, and second, by inhibiting the Matrix Metalloproteinases (MMP-1 and MMP-3) responsible for collagen breakdown. Simultaneously, it stimulates the transcription of the COL1A1 gene to accelerate Type I collagen synthesis and suppress inflammatory markers like NF-κB and TNFα.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Demonstrated significant increase in Type I collagen synthesis and cell proliferation in human dermal fibroblasts at concentrations of 10–100 μg/ml (2022).
- 02 Confirmed inhibition of inflammatory adhesion molecules (ICAM-1, VCAM-1) and ROS production at 50 μg/mL dosage.
- 03 Established 93% antibacterial efficacy against S. aureus and E. coli at a 10% leaf extract concentration (2024).
Transparency
Dusting Analysis
Due to its deep natural pigment and high potency, many brands include it at negligible percentages (below 0.05%) for marketing claims. Efficacy for collagen support typically requires concentration levels starting at 0.1% or higher in stabilized aqueous solutions.
The Formula
Formulation
Stability
Highly pH-dependent; bioactive anthocyanins degrade and shift color in alkaline environments. Must be kept in opaque, cool storage to prevent photo-degradation of polyphenols.
Synergies
- L-Ascorbic Acid
- Ferulic Acid
- Hyaluronic Acid
- Zinc PCA
Conflicts
- Alkaline formulations (pH >7.0)
- Strong oxidizing agents
- High-heat processing
- Simple glucose/fructose solutions
Safety
