ZLEY\u00aeUP (INCI: Undecylenoyl Phenylalanine), also known as Sepiwhite<\/strong>, is a premium skin-brightening agent used in high\u2011end brightening and spot\u2011correcting products such as SK-II and OLAY.<\/p>\n\n\n\n

As a structural analog of \u03b1-melanocyte-stimulating hormone (\u03b1-MSH), Undecylenoyl Phenylalanine competitively binds to MC1-R receptors on melanocytes, effectively blocking the cAMP\/PKA signaling pathway. This action reduces the expression of key melanogenic enzymes and directly inhibits tyrosinase activity, thereby significantly decreasing melanin production for visible brightening and spot-fading results.<\/p>\n\n\n\n

ZLEY\u00ae is a professional supplier of Undecylenoyl Phenylalanine (CAS 175357-18-3), providing stable quality, technical support, and global delivery covering over 60 countries.<\/p>\n\n\n\n
