Argireline vs Sermorelin

Side-by-side comparison of key properties, dosing, and research.

Skin & Cosmetic
Argireline
Growth Hormone PeptidesAnti-Aging & Longevity
Sermorelin
Summary
Argireline is the most widely researched topical 'Botox-alternative' cosmetic peptide, an acetylated hexapeptide that inhibits neuromuscular transmission to relax facial muscles and reduce dynamic wrinkle depth by 17–27% in clinical studies.
Sermorelin is a bioidentical synthetic peptide comprising the first 29 amino acids of naturally occurring GHRH. It is FDA-approved for diagnostic use and widely prescribed off-label for anti-aging, stimulating growth hormone production in a natural pulsatile pattern that mimics the body's own rhythm.
