Science
Mechanism of Action
This ingredient operates via a dual-action pathway: it serves as a potent tyrosinase inhibitor to block melanin synthesis at the source, while simultaneously acting as a reactive oxygen species (ROS) scavenger to mitigate 'anti-inflammaging'—the process where environmental stress triggers premature skin degradation.
Research
Clinical Evidence
High confidence1.5%
Key findings
- 01 In-vitro patent testing demonstrated significant melanin reduction at concentrations as low as 10-1000 ppm, outperforming pure caffeic acid.
- 02 8-week clinical trials using standardized 1-3% solutions showed measurable improvements in skin luminosity and a reduction in localized hyperpigmentation.
Transparency
Dusting Analysis
Because this peptide is efficacious at extremely low parts-per-million (ppm), it is often 'dusted' into formulas at negligible levels for marketing purposes. For true corrective results, we look for concentrations aligned with clinical supplier data (0.1% to 3%).
The Formula
Formulation
Stability
Heat sensitive; must be integrated during the cooling phase below 40°C to maintain peptide integrity. Stable in standard storage when kept within physiological pH ranges.
Synergies
- Niacinamide
- Vitamin C derivatives
- Hyaluronic Acid
Conflicts
- Strong oxidizers
- Proteolytic enzymes
- Extreme pH environments (<3.0 or >9.0)
Safety
Safety Profile
While not yet formally reviewed by the CIR, its constituent parts (caffeic acid and amino acids) have well-established safety profiles in cosmetic use.
