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

Is ZLEY\u00aeUP Safe?<\/strong><\/p>\n\n\n\n

Yes. ZLEY\u00aeUP is considered safe for cosmetic use under normal, reasonable, and foreseeable conditions at concentrations fino a 2,01 TP3T<\/strong> in both leave-on and rinse-off products (for rinse-off, the same limit applies by referencing leave-on usage data).<\/p>\n\n\n\n

Applicazioni del prodotto<\/strong><\/p>\n\n\n\n

In cosmetics and skincare, ZLEY\u00aeUP functions primarily as a agente emolliente<\/strong>. Its lipid-amino acid structure provides excellent skin affinity, making it suitable for sensitive skin in brightening, spot-correcting, and antioxidant formulations, as well as compound liposome development. It has become a benchmark ingredient in efficacy-driven skincare. By combining it with niacinamide, adenosine, and other actives, formulators can build full-pathway brightening systems that deliver both safety and high performance, continuously empowering brands.<\/p>\n\n\n\n
