What is Lipopeptide (Cosmetic)?

Tap any underlined term for an instant definition.

Lipopeptides are a class of compounds combining fatty acid chains (lipid components) with peptide sequences. In cosmetic and topical research, the lipid modification (typically a palmitoyl, myristoyl, or lauroyl chain) serves primarily to enhance peptide penetration through the hydrophobic stratum corneum, which naturally resists water-soluble peptide passage.

What It Is

  • A broad class of fatty acid-conjugated peptides for topical skin use
  • The lipid modification (palmitoyl C16, myristoyl C14, or lauroyl C12) enhances skin penetration
  • Includes well-characterized compounds: Pal-GHK, Pal-GQPR, Pal-AHK, SNAP-8, Leuphasyl
  • Used across anti-aging, skin brightening, and wound repair research

How It Works

  • The fatty acid tail intercalates into stratum corneum lipid lamellae, dragging the attached peptide sequence into the epidermis and dermis
  • Once in target tissue, the peptide sequence exerts its specific biological effect (collagen stimulation, enzyme inhibition, receptor binding, etc.)
  • Lipid modification typically increases skin retention time vs unmodified peptide by 3-5 fold

Key Research Areas

  • The palmitoyl (C16) modification is the most studied: used in Pal-GHK (Palmitoyl Tripeptide-1), Pal-GQPR (Palmitoyl Tetrapeptide-7), Pal-AHK, and Pal-KTTKS (Palmitoyl Pentapeptide-4/Matrixyl)
  • Enhanced collagen production across multiple matrix-stimulating lipopeptides
  • Reduced expression wrinkle depth in clinical studies for SNAP-8 and Matrixyl formulations

Dosing From the Literature

  • Topical concentration varies by specific lipopeptide: 0.1-5% in formulation
  • Applied once or twice daily to target skin areas

Storage and Handling

  • Lyophilised: 2-8 degrees C for most compounds
  • In formulation: stable at pH 4-7 for most palmitoyl peptides
  • Some lipopeptides crystallize below 15 degrees C; allow to reach room temperature before use
