ZLEY®377PRO – Phenylethyl Resorcinol Liposome-10:
Enhanced Penetration, True Brightening – 1 Bottle Equals 8
Productos
ZLEY®377PRO (Phenylethyl Resorcinol Liposome-10) is a skin conditioning agent featuring the powerful brightening active Feniletilresorcinol (also known as “377”) delivered via advanced liposome–targeted delivery technology. This system breaks through the absorption barrier between the active ingredient and the skin, acting like an “elevator” to deliver 377 deep into the basal layer within 8 hours, achieving 8.67 times higher transdermal penetration compared to conventional 377 – delivering the equivalent of 8 bottles in 1.
True brightening – reducing dullness and yellow tones – it promotes the expression of Nrf2 antioxidant factors, enhancing the skin’s antioxidant defense capacity. Inhibits MITF protein expression, downregulates tyrosinase and TRP-2 expression, and suppresses melanin production at the source to improve dull and yellow skin tone.

In cosmetics and skincare, ZLEY®377PRO functions primarily as a agente acondicionador de la piel. It is suitable for emulsions, creams, gels, and water-based formulations, making it ideal for brightening and spot-correcting products.
Filosofía de desarrollo de productos
To address the three major challenges of Phenylethyl Resorcinol (“377”) – poor skin penetration, low stability, and poor water solubility – ZLEY®’s R&D team innovatively developed liposome–targeted delivery technology. This technology breaks through the stratum corneum’s “brick-and-mortar” barrier structure, delivering 377 faster, more accurately, and more efficiently to the basal layer. It targets melanocytes directly, inhibiting melanin production at the source. This targeted delivery system significantly enhances the bioavailability and brightening efficacy of the active ingredient.

Preguntas frecuentes (FAQ)
Q1: What is the liposome delivery technology used in ZLEY®377PRO?
A: The liposome delivery system encapsulates Phenylethyl Resorcinol (“377”) within lipid bilayers, protecting it from degradation while enabling efficient transport across the stratum corneum. This “elevator-like” targeted delivery ensures the active ingredient reaches the basal layer where melanocytes reside, achieving 8.67‑fold higher transdermal penetration than conventional 377.
Q2: What is the recommended usage level?
R: El rango de uso recomendado es 0.5–3.3% . For optimal brightening efficacy, we recommend starting at 1–2% and adjusting based on formulation type and target market requirements.
Q3: What is the difference between ZLEY®377PRO and conventional 377 (Phenylethyl Resorcinol)?
A: Conventional 377 has poor water solubility, low stability, and limited skin penetration. ZLEY®377PRO is a liposome-encapsulated system that solves all three challenges, delivering significantly higher bioavailability and superior brightening results at lower effective concentrations.
Q4: Is ZLEY®377PRO suitable for sensitive skin?
A: The liposome encapsulation provides controlled release of the active ingredient, reducing the potential for irritation compared to conventional 377. However, we recommend compatibility testing for specific formulations targeting sensitive skin.
