Science
Mechanism of Action
Acetyl Tripeptide-30 Citrulline operates by preventing the breakdown of the extracellular matrix (ECM) through potent inhibition of various matrix metalloproteinase (MMP) enzymes. It specifically targets and inhibits MMP-1, MMP-2, MMP-3, and MMP-9, which are known to degrade collagen and other vital skin proteins. By preserving these structural components, it supports the skin's firmness, elasticity, and overall youthful appearance.

Key findings
- 01 Studies demonstrated that Acetyl Tripeptide-30 Citrulline completely inhibits the activity of MMP-2, an enzyme crucial for degrading type I collagen fibers. Furthermore, it showed a significant inhibition of MMP-9 by 63.1%, and inhibited MMP-1 and MMP-3 by 35% to 40%.

The Formula
Formulation
Stability
The stability of peptides like Tripeptide-30 is inherently sequence-dependent. Degradation pathways can include hydrolysis, deamidation (which is sharply accelerated at alkaline pH), and oxidation (which progresses faster above pH 7). Maintaining proper storage conditions is crucial for peptide longevity, and robust formulation stability is essential for commercial product viability. Peptides are typically formulated within hydrophilic mediums.
Safety
Safety Profile
While Acetyl Tripeptide-30 Citrulline specifically has not undergone formal review by CIR, SCCS, or FDA, general peptides, such as Tripeptide-1, are often considered well-tolerated and safe for cosmetic use at typical concentrations, often below 10 ppm. Therefore, the sensitization risk is generally considered low, though specific review for this peptide is pending.
