Argireline vs Cagrilintide

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

Skin & Cosmetic
Argireline
GLP-1 / Weight Loss Agonists
Cagrilintide
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.
Cagrilintide is a long-acting amylin analog developed by Novo Nordisk. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells. Cagrilintide slows gastric emptying, suppresses glucagon, and reduces appetite via central amylin receptors. In combination with semaglutide (CagriSema), Phase 2 trials achieved approximately 15% body weight reduction. Phase 3 trials (REDEFINE program) are ongoing.

Key Benefits
  • Reduces depth of dynamic expression wrinkles 17–27%
  • Non-invasive topical Botox alternative
  • Smooths forehead, eye area, nasolabial fold lines
  • Widely studied — published clinical efficacy data
  • Synergistic with SNAP-8 for enhanced effect
  • Reduces fine lines around eyes (crow's feet)
  • Improves skin smoothness and texture
  • Well tolerated across all skin types
  • ~15% body weight reduction in combination with semaglutide (CagriSema Phase 2)
  • Synergistic appetite suppression complementing GLP-1 receptor agonists
  • Reduces post-meal glucagon excursions improving glycemic control
  • Slows gastric emptying contributing to prolonged satiety
  • Once-weekly dosing via subcutaneous injection
  • Potential for greater weight loss than semaglutide monotherapy
Side Effects
  • Generally very well tolerated
  • At >10%: temporary eyelid/brow ptosis (drooping)
  • Rare: mild redness in sensitive skin
  • No systemic absorption at cosmetic doses
  • Nausea (most common, especially during titration)
  • Vomiting
  • Decreased appetite
  • Diarrhea
