Palmitoyl Tetrapeptide-20 Amide, with the sequence Pal-Pro-Glu-Lys-Lys-NH2, is a synthetic peptide that is widely used in the cosmetics industry for its potential to modulate skin pigmentation and support skin health. This peptide is known for its ability to mimic the effects of alpha-melanocyte-stimulating hormone (α-MSH), which can help in reducing the appearance of hyperpigmentation and promoting an even skin tone. Its lipophilic nature, due to the palmitoyl group, enhances its ability to penetrate the skin and deliver benefits effectively. It also promotes hair growth and eyelash growth.
