Acetyl Tetrapeptide-3 is a biomimetic peptide designed to mimic the effects of natural growth factors. It is commonly found in hair and lash growth serums, where it is believed to stimulate collagen production and improve the integrity of the dermal papilla. This can lead to stronger hair follicles and potentially thicker, fuller hair.
