Question

Myristoyl hexapeptide-5 is unavailable. What are the recommended substitutes for use in cosmetics?

Answer

Since Myristoyl hexapeptide-5 is currently unavailable, we recommend the following peptide substitutes that share similar structures and functions, particularly in stimulating keratin production for eyelash and hair growth:

Recommended Substitutes (Eyelash & Hair Growth Group)

  1. Pep®-235 (Myristoyl Hexapeptide-16 1000ppm)

    • Properties: This is the closest structural substitute (both are hexapeptides with a myristoyl tail). It specifically stimulates keratin genes (Keratin 3, 19) to promote thicker and fuller eyelashes.
    • Usage Rate: 2-10%
    • Mixing: Mix in the water phase; avoid heat.
  2. Myristoyl pentapeptide-4 (1000ppm Solution)

    • Properties: A synthetic peptide that significantly increases the skin's own keratin levels. It is highly effective for promoting eyelash and hair growth by activating keratin genes.
    • Usage Rate: 5-10%
    • Mixing: Mix in the water phase; avoid heat.
  3. Long-Lash™ (Myristoyl Pentapeptide-17, Copper Tripeptide-1)

    • Properties: A synergistic blend of two peptides that work together to stimulate keratin genes. It is a popular choice for eyelash serums, showing visible results in 2-6 weeks.
    • Usage Rate: 5-10%
    • Mixing: Mix in the water phase. Note: Do not use with EDTA or AHAs as they can deactivate the Copper Peptide component.

Selection Guidance

  • For the closest structural match, choose Pep®-235 (Myristoyl Hexapeptide-16).
  • For a proven functional alternative for eyelash growth, Long-Lash™ or Myristoyl pentapeptide-4 are excellent choices.
