Nonapeptide-1
Summary
Cerebrolysin is a porcine brain-derived neuropeptide complex that mimics the action of endogenous neurotrophic factors (BDNF, NGF, GDNF, NT-3). It promotes neurogenesis, neuroprotection, and synaptic plasticity, and is approved in many countries for stroke, traumatic brain injury, and Alzheimer's disease.
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
  • Promotes neurogenesis and synaptic plasticity
  • Approved for stroke rehabilitation (accelerates recovery)
  • Alzheimer's disease: slows progression and improves cognition
  • Traumatic brain injury recovery
  • Enhances memory and executive function
  • Neuroprotection against oxidative stress and excitotoxicity
  • Anti-amyloid and anti-tau effects
  • Mood improvement and reduced anxiety
  • 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 nausea and dizziness (IV infusion)
  • Headache at initiation
  • Rare: agitation (usually at very high doses)
  • +2 more
  • Generally very well-tolerated
  • Rare contact sensitivity in susceptible individuals
  • Theoretical risk of excessive depigmentation with prolonged high-concentration use
