LL-37 99% High Purity Peptide Powder 5 mg/vial

LL-37 is a 37-amino acid cationic antimicrobial peptide (AMP) and the only known human cathelicidin-derived peptide. It is produced by immune cells (neutrophils, macrophages) and epithelial cells (skin, gut, respiratory tract). LL-37 has multiple functions:

• Direct antimicrobial activity – Disrupts microbial membranes, killing bacteria (including MRSA), fungi, and enveloped viruses

• Immunomodulation – Regulates cytokine production and reduces excessive inflammation

• Wound healing – Promotes angiogenesis, re-epithelialization, and granulation tissue formation

• Skin barrier enhancement – Supports the skin's natural defense against pathogens

Due to these properties, LL-37 is studied for acne, rosacea, chronic wounds, and immune-related skin conditions. Our LL-37 is supplied as a high-purity (99%+) lyophilized powder, 5 mg per vial, with CAS 154947-66-7.

Why Choose LL-37?
Natural immune defense for skin. LL-37 is part of your body's first line of defense. Adding it to skincare formulations can help support the skin's ability to fight harmful microbes while calming inflammation.
Promotes faster healing. LL-37 accelerates wound closure and tissue repair, making it valuable for post-procedure recovery, minor cuts, or chronic skin issues.
Broad-spectrum antimicrobial action. Unlike single-target ingredients, LL-37 works against a wide range of bacteria, fungi, and viruses – including antibiotic-resistant strains – making it a powerful addition to acne or infection-prone skin products.
Anti-inflammatory benefits. LL-37 helps balance immune responses, reducing redness and irritation without suppressing the skin's natural defenses.
Ready to ship. Vacuum-sealed, discreet packaging with cold chain options available. Every batch includes COA documentation.
