Myristoyl Pentapeptide-12 is a synthetic peptide that is recognized for its potential to promote hair growth, particularly for eyelashes and eyebrows, by stimulating keratin gene expression and enhancing the development of the dermal papilla, which is crucial for hair growth. In addition to its effects on hair, Myristoyl Pentapeptide-12 has also been noted for its ability to improve the appearance of the skin by increasing keratinocyte proliferation, which can lead to improved skin firmness, elasticity, and thickness. This peptide enhances skin firmness and elasticity, making it a valuable ingredient in skincare formulas designed to reduce signs of aging and improve skin texture.
