Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: Copper Peptide, Glycyl-L-histidyl-L-lysine copper
A naturally occurring copper-binding peptide found in human plasma, saliva, and urine. Widely used in skincare for its wound healing and anti-aging properties.
Also: Acetyl Hexapeptide-3, Acetyl Hexapeptide-8
A popular cosmetic peptide that reduces facial wrinkles by inhibiting neurotransmitter release. One of the most widely used peptides in anti-aging skincare.
Key Comparison Insights
- Both peptides belong to the Skin & Hair category, suggesting similar primary applications.
Detailed Comparison
| Attribute | GHK-Cu | Argireline |
|---|---|---|
| Category | Skin & Hair | Skin & Hair |
| FDA Status | Not FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | GHK-Cu stimulates collagen and elastin synthesis, promotes glycosaminoglycan production, supports blood vessel growth, and has antioxidant and anti-inflammatory properties. It remodels damaged tissue and activates wound-healing genes. | Argireline mimics the N-terminal of SNAP-25 protein, inhibiting SNARE complex formation necessary for muscle contraction. This reduces facial muscle movement and subsequently wrinkle formation, similar to but milder than botulinum toxin. |
| Common Dosing | 1-2 mg daily (injection) or topical Once daily | Limited community data available See research protocols |
| Administration | Subcutaneous injection or topical application | Topical (serums, creams) |
| Typical Duration | Varies by application | Ongoing use for maintained effects |
| Best Time to Take | Evening (for skin/recovery) | Morning and evening (topical) |
Possible Side Effects May vary by individual |
|
|
| Research Summary | Studies demonstrate increased collagen synthesis, improved skin elasticity, reduced fine lines, and accelerated wound healing. Research shows it can reset gene expression to a healthier state and may have systemic anti-aging effects beyond skin. | Studies demonstrate 30% reduction in wrinkle depth after 30 days of use. Research shows effectiveness particularly for expression lines around eyes and forehead. Well-established safety profile with decades of cosmetic use. |
