| Aspect | Palmitoyl Tetrapeptide-7 | Thymalin |
|---|---|---|
| Mechanism | Suppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides. | Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production. |
| Typical Dosage | Topical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex. | Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance. |
| Administration | Topical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin. | Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols. |
| Side Effects | Excellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin. | Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated. |
