Myristoyl pentapeptide-17, a liposomal peptide, is an engineered peptide reacted with lipids (fats) to introduce peptides into living keratin cells. The peptides (myristoyl pentapeptide-17) combined with the liposomes are engineered to be identical to peptides produced in the follicle that instruct cells to produce more keratin. Myristoyl pentapeptide-17 can directly stimulate the increased synthesis of keratin within keratin cells without requiring biological growth factors.

Liposomal proteins are identical copies of biological proteins, making them safer and significantly more effective than other hair-thickening agents. They can specifically and selectively stimulate keratin production within the cell, increasing the size and weight of the keratin cell by 60-100%.
