| Aspect | Thymosin Alpha-1 | Matrixyl |
|---|---|---|
| Mechanism | Enhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes. | Mimics collagen breakdown fragments, triggering fibroblasts to produce new collagen, elastin, and other matrix components. Essentially tricks skin into repair mode without actual damage. |
| Typical Dosage | Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary. | Topical: 2-8% concentration in serums and creams. Matrixyl 3000 combines it with Palmitoyl Tetrapeptide-7 for enhanced effects. |
| Administration | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. | Topical application 1-2 times daily. Can be combined with other actives like retinol, vitamin C, and other peptides. |
| Side Effects | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. | Very well-tolerated. Rare mild irritation. Suitable for sensitive skin types. |
