Myristoyl Tetrapeptide-12 is a synthetic lipopeptide composed of a myristic acid chain attached to a tetrapeptide sequence (proline, proline, tyrosine, leucine). The myristoyl group enhances the peptide’s lipophilicity, allowing it to penetrate the stratum corneum and deliver bioactive amino acid sequences to the deeper layers of the skin. This peptide is designed for cosmetic applications, particularly in anti-aging and skin-restructuring formulations.
In advanced cosmetic products, this peptide is used at low concentrations (typically 1-5%) to stimulate collagen production, reduce the appearance of fine lines, and improve overall skin firmness. Its compatibility with a wide range of emulsion systems makes it a versatile ingredient for serums, creams, and lotions targeting mature or stressed skin.
