Skin & Cosmetic
Nonapeptide-1
Summary
Vesugen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for blood vessels and the vascular endothelium. It supports endothelial cell function, promotes vascular wall integrity, and is studied for atherosclerosis prevention, vascular aging, and cardiovascular health maintenance. It is one of the more broadly applicable Khavinson bioregulators given the ubiquity of vascular tissue.
Nonapeptide-1 is a synthetic 9-amino acid peptide that inhibits melanin production by blocking α-MSH (alpha-melanocyte stimulating hormone) receptor binding. Used in cosmetic formulations for skin lightening and evening skin tone, it is particularly effective for UV-induced and hormonal hyperpigmentation.

Key Benefits
  • Supports vascular endothelial cell function and integrity
  • May reduce endothelial inflammation and dysfunction
  • Anti-aging effects on blood vessel walls
  • Potential benefits in early atherosclerosis and vascular aging
  • Supports nitric oxide-mediated vascular tone
  • Reduces endothelial apoptosis from oxidative stress
  • Complementary to Cardiogen and Epithalon in cardiovascular longevity protocols
  • Inhibits UV-induced tanning and hyperpigmentation
  • Reduces hormonal melasma
  • Evens skin tone at receptor level
  • Well-tolerated with minimal irritation
  • Complementary to tyrosinase inhibitors for enhanced brightening
  • Reduces post-inflammatory hyperpigmentation
Side Effects
  • Generally well tolerated
  • Mild injection site reactions
  • No significant vascular adverse events reported at standard doses
  • Generally very well-tolerated
  • Rare contact sensitivity in susceptible individuals
  • Theoretical risk of excessive depigmentation with prolonged high-concentration use
