Myristoyl Pentapeptide-4 is a synthetic peptide engineered for topical cosmetic use, designed to mimic a fragment of collagen and stimulate the skin’s natural repair processes. Its structure features a myristic acid chain attached to a pentapeptide sequence (Tyr-Ile-Gly-Ser-Arg), which enhances lipophilicity and skin penetration, allowing the peptide to reach deeper dermal layers where it can exert its effects.
This peptide is widely recognized in the cosmetic industry as a signaling peptide that promotes collagen production, improves skin firmness, and reduces the appearance of fine lines and wrinkles. It is commonly used in anti-aging formulations, serums, and creams, and is valued for its stability and compatibility with a range of cosmetic ingredients.
