Science
Mechanism of Action
This ingredient operates as a dual-action bio-modulator; it utilizes the antimicrobial and brightening capabilities of Azelaic Acid to calm the skin surface while the tetrapeptide component stimulates essential growth factors (PDGF-A and HGF) to support the dermal matrix and inhibit pro-inflammatory cytokines.

Key findings
- 01 In vitro studies on the base Tetrapeptide-32 demonstrated significant increases in PDGF-A and HGF expression, leading to a 176% increase in hair follicle length at 20 ppm.
- 02 Commercial skincare applications have validated its use in reducing visible facial redness and soothing hypersensitive skin barriers.
Transparency
Dusting Analysis
Because this peptide is active at extremely low concentrations (parts per million), it is frequently included in formulations at 'label-only' levels that fall below the 20 ppm threshold required for physiological impact.
The Formula
Formulation
Stability
Heat sensitive; must be incorporated during the cool-down phase of formulation at temperatures below 40°C to prevent peptide degradation.
