Science
Mechanism of Action
This peptide functions as a signaling molecule with inherent antioxidant properties. Its core mechanism involves stimulating the dermal synthesis of key extracellular matrix proteins, including collagen, elastin, and fibronectin. This regenerative action directly targets concerns such as fine lines, wrinkles, and sagging, promoting a more youthful, firm, and hydrated complexion.

Dusting Analysis
Without specific clinical efficacy data or commonly recognized effective concentrations, it is not possible to assess if Tetrapeptide-1 is typically used at concentrations considered to be 'dusting' levels.
The Formula
Formulation
Stability
Tetrapeptide-1 maintains stability under standard cosmetic formulation conditions. For optimal integrity, it should be incorporated into the water phase at temperatures below 40°C. Storage for the powder form is recommended at -80°C for up to 2 years or -20°C for 1 year, while in solvent, it should be stored at -80°C for 6 months or -20°C for 1 month, always in sealed containers away from moisture.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet conducted a specific safety assessment for Tetrapeptide-1 (Leu-Pro-Thr-Val). While the CIR has reviewed other tetrapeptides (e.g., Palmitoyl Tetrapeptide-7, Tripeptide-1, Hexapeptide-12), this particular peptide currently lacks a formal safety review.

Verdict
Tetrapeptide-1 presents a promising mechanism for improving skin structure and combating aging signs, but further comprehensive clinical efficacy data and a formal CIR safety review are needed for a conclusive assessment.
