Skin & Cosmetic
Nonapeptide-1
Summary
MOTS-c is a mitochondria-derived peptide (MDP) encoded within the mitochondrial genome. It acts as a metabolic regulator, improving insulin sensitivity, enhancing exercise capacity, and counteracting age-related metabolic decline. It is often called a 'mitochondrial hormone.'
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
  • Improves insulin sensitivity and glucose metabolism
  • Enhances exercise capacity and endurance
  • Reduces age-related metabolic decline
  • Activates AMPK — the master metabolic regulator
  • Promotes fat oxidation
  • Anti-inflammatory effects
  • May extend healthspan via mitochondrial optimization
  • Increases energy and reduces fatigue
  • 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
  • Injection site irritation
  • Fatigue during initial adaptation
  • Unknown long-term profile (limited human data)
  • Generally very well-tolerated
  • Rare contact sensitivity in susceptible individuals
  • Theoretical risk of excessive depigmentation with prolonged high-concentration use
