Produkt\u00fcbersicht<\/strong><\/p>\n\n\n\n

ZLEY\u00ae577PRO (4-Butylresorcinol Liposome-135) features liposome<\/strong>\u2013<\/strong>targeted delivery technology<\/strong> that protects the brightening active “577” (4-Butylresorcinol) and delivers it directly to the basal layer of the skin. The system provides sustained release<\/strong> of 577, targeting melanocyte stem cells and acting at both melanin synthesis and post\u2011synthesis stages to synergistically inhibit melanin production, fade surface pigmentation, and deliver gentle brightening and spot\u2011correcting effects.<\/p>\n\n\n\n
