Argireline vs BNP (B-type Natriuretic Peptide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Argireline
Argireline (Acetyl Hexapeptide-3) is a widely-used cosmetic peptide that reduces wrinkle depth by inhibiting neurotransmitter release. One of the first 'Botox-like' peptides developed for topical use.
Full details →BNP (B-type Natriuretic Peptide)
BNP is a cardiac neurohormone released primarily by ventricles in response to volume/pressure overload. It's a major biomarker for heart failure and has therapeutic applications as nesiritide.
Full details →Side-by-Side Comparison
| Aspect | Argireline | BNP (B-type Natriuretic Peptide) |
|---|---|---|
| Mechanism | Inhibits the formation of the SNARE complex required for neurotransmitter release, reducing the intensity of muscle contractions that cause expression lines. | Similar to ANP - activates NPR-A receptors to produce vasodilation, natriuresis, and RAAS suppression. Released in response to ventricular wall stress. |
| Typical Dosage | Topical: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments. | Nesiritide (recombinant BNP): 2mcg/kg IV bolus followed by 0.01mcg/kg/min continuous infusion for acute decompensated heart failure. |
| Administration | Topical application to clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results. | Intravenous administration only. Used in acute care settings for heart failure. BNP levels also used diagnostically. |
| Side Effects | Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses. | Hypotension (common and dose-limiting), headache, nausea, and potential renal function worsening in some patients. |
