| Aspect | Argireline | Semax |
|---|---|---|
| Mechanism | Inhibits the formation of the SNARE complex required for neurotransmitter release, reducing the intensity of muscle contractions that cause expression lines. | Enhances BDNF expression, modulates dopamine and serotonin systems, and provides neuroprotective effects. Increases attention, memory formation, and learning. |
| Typical Dosage | Topical: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments. | Intranasal: 200-600mcg 2-3 times daily. Higher doses (up to 1mg) used in clinical settings for stroke recovery. |
| Administration | Topical application to clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results. | Primarily administered intranasally. N-Acetyl Semax Amidate (NASA) is a modified version with enhanced stability and potency. |
| Side Effects | Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses. | Generally well-tolerated. May cause mild irritability or hair shedding in some users. |
