Science
Mechanism of Action
This peptide acts as a molecular switch, suppressing the MAPK/AP-1 and NF-κB signaling pathways to inhibit the production of collagen-degrading enzymes (MMP-1, MMP-2, MMP-3). Simultaneously, it functions as a radical scavenger and histamine inhibitor, effectively neutralizing pro-inflammatory cytokines like IL-6 and IL-8 to stop the cycle of itching and irritation while stimulating fibroblast proliferation for structural recovery.

Key findings
- 01 UVB-induced photoaging inhibition via MAPK/AP-1 suppression (Journal of Photochemistry and Photobiology B, 2010)
- 02 99% satisfaction rate in in-vivo microneedle patch trials for immediate relief of skin pruritus and irritation (Raphas Clinical Data)

Dusting Analysis
Due to its high biological activity at very low concentrations (starting at 0.0006%), it is rarely 'dusted' in the traditional sense, but peak efficacy for structural repair is consistently observed closer to the 0.1% concentration.
The Formula
Formulation
Stability
Demonstrates superior thermal and solution stability compared to free caffeic acid, effectively resisting oxidative browning. It remains stable in standard emulsions but degrades in extreme pH environments.
