Nonapeptide-1 vs Vesilute

Side-by-side comparison of key properties, dosing, and research.

Skin & Cosmetic
Nonapeptide-1
Anti-Aging & Longevity
Vesilute
Summary
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.
Vesilute is a tetrapeptide bioregulator (Lys-Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific for the retina and visual system. It supports retinal cell function, promotes normalization of photoreceptor protein synthesis, and is studied for age-related macular degeneration (AMD), retinal aging, and vision preservation in the elderly.

Key Benefits
  • 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
  • Supports retinal photoreceptor cell function and survival
  • May slow progression of age-related macular degeneration
  • Reduces retinal cell apoptosis from oxidative stress and aging
  • Anti-aging effects on retinal pigment epithelium
  • Potential support in diabetic retinopathy management
  • Preserves visual acuity with aging
  • Complementary to lutein, zeaxanthin, and NAD+ in ocular health protocols
Side Effects
  • Generally very well-tolerated
  • Rare contact sensitivity in susceptible individuals
  • Theoretical risk of excessive depigmentation with prolonged high-concentration use
  • Generally well tolerated
  • Mild injection site reactions
  • No significant ocular adverse events reported at standard doses
