(Myristoyl Pentapeptide-4 + Hexapeptide-3)
These matrikine-like peptides act as cellular messengers that signal the nail matrix to produce keratin more efficiently. Research in keratin-dense tissues shows peptides can upregulate keratin gene expression. Myristoyl Pentapeptide-4 supports growth rate. Hexapeptide-3 reinforces structural integrity. Together, they address the biological slowdown that causes ridging, peeling, and slow recovery after damage.
