Science
Mechanism of Action
This ingredient utilizes a capsaicinyl moiety to engage TRPV1 receptors, boosting blood flow and nutrient delivery to follicles and skin cells without a burning sensation. Simultaneously, the Tripeptide-1 (GHK) component signals the skin to synthesize essential extracellular matrix proteins like collagen and elastin, while the succinoyl bridge ensures deep, stable delivery of these active signals.
Research
Clinical Evidence
Medium confidence3%
Key findings
- 01 In vitro testing confirmed a significant increase in VEGF and IGF-1 growth factors within human dermal papilla cells, essential for hair follicle vitality.
- 02 A 12-week clinical evaluation of a 3% solution demonstrated a measurable reduction in telogen phase (shedding) hair and enhanced hair anchoring efficacy.

Dusting Analysis
Because it is a complex peptide-derivative, brands often include it at trace amounts (under 0.1%) just for label claims. For genuine scalp revitalization or hair density benefits, concentrations between 1% and 3% are required.
The Formula
Formulation
Stability
Highly stable in water-based serums but prone to degradation via hydrolysis if the formula's pH drops below 3.0 or rises above 8.5. Using polyols like glycerin can further stabilize the peptide chain.
Synergies
- Glycerin
- Butylene Glycol
- Panthenol
- Caffeine
Conflicts
- Strong oxidizing agents
- Proteolytic enzymes
- Extreme pH environments
Safety
Safety Profile
While the specific derivative is awaiting a formal CIR panel review, it is listed as safe in the EU CosIng database and the Tripeptide-1 base is well-documented for its safety profile.
