| Aspect | Palmitoyl Tetrapeptide-7 | Palmitoyl Tripeptide-1 |
|---|---|---|
| Dose Range | 500 mcg–2 mg | 500 mcg–2 mg |
| Frequency | 2x daily | 2x daily |
| Cycle Length | 4–12 weeks | 4–12 weeks |
| Route | topical | topical |
| Mechanism | Suppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides. | Mimics the skin's own mechanism for producing collagen by acting as a messenger peptide that signals fibroblasts to produce more collagen and other extracellular matrix components. |
| Typical Dosage | Topical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex. | Topical: Typically 2-4% in serums, often combined with Palmitoyl Tetrapeptide-7 as Matrixyl 3000. |
| Administration | Topical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin. | Topical application 1-2 times daily. The palmitoyl group enhances skin penetration compared to non-lipidated versions. |
| Side Effects | Excellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin. | Very well-tolerated. Suitable for most skin types including sensitive skin. |
