Epigen vs Lactoferricin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epigen
Epigen is a member of the epidermal growth factor (EGF) family. It plays roles in skin regeneration and has been studied for wound healing and anti-aging applications.
Full details →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.

| Aspect | Epigen | Lactoferricin |
|---|---|---|
| Mechanism | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. | Binds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects. |
| Typical Dosage | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. | Research applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily. |
| Administration | Primarily topical application for skincare. Research may use other routes for systemic effects. | Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings. |
| Side Effects | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. | Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies. |
