Lactoferricin vs Argireline
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Lactoferricin
Lactoferricin is an antimicrobial peptide derived from lactoferrin, a protein found in milk and other secretions. It has potent antibacterial, antiviral, and antifungal properties.

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.

| Aspect | Lactoferricin | Argireline |
|---|---|---|
| Mechanism | Binds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects. | Inhibits the formation of the SNARE complex required for neurotransmitter release, reducing the intensity of muscle contractions that cause expression lines. |
| Typical Dosage | Research applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily. | Topical: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments. |
| Administration | Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings. | Topical application to clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results. |
| Side Effects | Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies. | Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses. |
