Vialox
Summary
GHK-Cu is a naturally occurring copper complex that declines with age. It is one of the most studied anti-aging peptides, known for powerful skin rejuvenation, wound healing, and tissue remodeling effects.
Vialox is a synthetic pentapeptide that mimics the activity of conotoxin from cone snails, acting as an antagonist of nicotinic acetylcholine receptors at the neuromuscular junction. Similar to Syn-Ake but derived from cone snail venom biochemistry, it reduces facial muscle contraction to smooth expression wrinkles.

Key Benefits
  • Reduces wrinkles and fine lines
  • Improves skin firmness and elasticity
  • Accelerates wound healing
  • Reduces inflammation and oxidative damage
  • Promotes hair growth and thickness
  • Supports collagen and elastin production
  • May improve overall skin health and appearance
  • Resets aged fibroblast behavior
  • Anti-fibrotic — reduces scar tissue formation
  • Reduces dynamic wrinkles from repetitive facial expressions
  • Reversible muscle-relaxing effect without injection
  • Smooths forehead, periorbital, and perioral lines
  • Complementary to collagen-stimulating peptides
  • Well-studied tolerability in cosmetic concentrations
  • Can be combined with Syn-Ake for dual conotoxin/viper venom effect
Side Effects
  • Temporary blue-green discoloration at injection site (from copper — harmless)
  • Post-injection sting (brief)
  • Skin irritation with topical use (rare)
  • Generally very well-tolerated topically
  • Rare contact sensitivity or mild irritation
  • No clinically significant systemic neuromuscular effects at cosmetic doses
