Science
Mechanism of Action
It operates via the adenosine A2A receptor (A2AR) pathway, triggering essential signaling cascades including ERK and AKT. This molecular activation upregulates Growth Arrest Specific 6 (GAS6) and Hepatocyte Growth Factor (HGF), which together accelerate keratinocyte migration and Type I collagen synthesis while suppressing inflammatory histamine release.

Key findings
- 01 A 2025 study by Amorepacific and Eulji University demonstrated significant enhancement in fibroblast proliferation and COLIA1 expression via PDRN signaling.
- 02 Research from the University of Hohenheim (2019) confirmed the ingredient maintains structural stability and interfacial activity at a 2.5% protein fraction across extreme pH levels.
Transparency
Dusting Analysis
To achieve the PDRN-mediated regenerative benefits seen in clinical data, concentrations should meet or exceed 1%. Levels below 0.5% may provide minor soothing or emulsifying properties but fail to trigger the A2AR-dependent repair pathways.
The Formula
Formulation
Stability
Exhibits remarkable resilience to high ionic strength (up to 500 mM NaCl) and maintains integrity across a wide pH spectrum. Its natural emulsifying properties help stabilize oil-in-water systems.
