Pal-AHK vs Syn-Ake
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Pal-AHK is the palmitoylated form of the AHK-Cu copper tripeptide, created by attaching a palmitic acid chain to enhance skin penetration and lipid bilayer affinity. The palmitoyl modification significantly improves dermal bioavailability compared to unmodified AHK, making it particularly effective in anti-aging and hair growth formulations.
- Syn-Ake is a synthetic tripeptide that mimics waglerin-1, a peptide found in the venom of the Temple viper (Tropidolaemus wagleri). It acts as a reversible antagonist of muscular nicotinic acetylcholine receptors, temporarily reducing facial muscle contraction and smoothing dynamic wrinkles. Often called a 'synthetic Botox' in cosmetic marketing.

- Key Benefits
- Enhanced skin penetration vs. unmodified AHK-Cu
- Stimulates dermal collagen and elastin production
- Promotes hair follicle anagen phase
- Antioxidant and wound healing activity
- Firming and plumping effect on aging skin
- Improved bioavailability via lipid bilayer incorporation

- Well-studied in in vitro and clinical cosmetic trials
- Side Effects
- Generally well-tolerated
- Mild irritation at high concentrations in sensitive skin
- Possible comedogenicity at very high palmitate concentrations (formulation-dependent)
- Generally very well-tolerated topically
- Rare skin sensitivity or contact dermatitis
- Theoretical neuromuscular effects at systemic doses (not relevant topically)
