Cagrilintide- Summary
- Pal-GHK is the palmitoylated form of the GHK tripeptide without a copper ion. By conjugating palmitic acid to glycine-histidine-lysine, skin penetration is substantially enhanced, enabling deeper dermal collagen stimulation. It is commonly paired with Pal-GHK-Cu or GHK-Cu in anti-aging formulations.
- 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.

- 0.16 mg → 0.3 mg → 0.6 mg → 1.2 mg → 2.4 mg
- Frequency
- Once or twice daily
- Once weekly
- Key Benefits
- Stimulates collagen I and III synthesis in dermis
- Reduces the appearance of fine lines and wrinkles
- Improves skin elasticity and firmness
- Inhibits collagenase (MMP-1) to preserve existing collagen
- Enhances wound healing and skin repair
- Well-tolerated in anti-aging serums and creams
- ~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
- Rare skin irritation at very high concentrations
- Possible formulation-dependent comedogenicity
