Myristoyl Pentapeptide-17 is a potent ingredient renowned for its role in promoting eyelash growth. Its mechanism of action involves stimulating the expression of the keratin gene, a pivotal factor in the structural integrity of hair. This stimulation results in the increased proliferation of keratinocytes within the hair bulb, a crucial region for the development and nourishment of hair follicles. Myristoyl Pentapeptide-17 manifests its efficacy by imparting a dual benefit of both thickening and lengthening eyelashes. This transformative action contributes to an overall stronger and more voluminous appearance of the eyelashes, making it a highly sought-after ingredient for inclusion in eyelash serums and other formulations targeted at enhancing lash beauty.
