Productos
ZLEY®577PRO (4-Butylresorcinol Liposome-135) features liposome–targeted delivery technology that protects the brightening active “577” (4-Butylresorcinol) and delivers it directly to the basal layer of the skin. The system provides sustained release of 577, targeting melanocyte stem cells and acting at both melanin synthesis and post‑synthesis stages to synergistically inhibit melanin production, fade surface pigmentation, and deliver gentle brightening and spot‑correcting effects.

Preguntas frecuentes (FAQ)
Q1: How does the liposome delivery system work?
A: The liposome system encapsulates 4-Butylresorcinol within lipid bilayers, protecting it from degradation and enabling efficient transport across the stratum corneum. It delivers the active directly to the basal layer where melanocyte stem cells reside, and releases it gradually over time for sustained brightening efficacy.
Q2: What is the recommended usage level for ZLEY®577PRO?
R: El rango de uso recomendado es 1–10% depending on product type and desired efficacy. Specific safe maximums by product category apply (see Safety section above).
Q3: Is ZLEY®577PRO suitable for sensitive skin?
A: Yes. The liposome encapsulation provides controlled, sustained release of the active ingredient, significantly reducing the irritation potential compared to unencapsulated 4-Butylresorcinol. This makes it suitable for sensitive skin formulations.
Q4: What skin concerns does ZLEY®577PRO address?
A: It addresses hyperpigmentation concerns including melasma, sun spots, age spots, post-inflammatory hyperpigmentation (PIH), and uneven skin tone, while also providing antioxidant and radiance-enhancing benefits.
