The aim of this study was to develop and optimize α-arbutin-loaded nanostructured lipid carriers (Ar- NLCs) using the QbD. Additionally, the formulation studies, in-vitro and ex-vivo performance of Ar-NLCs were assessed, along with their cytotoxic efficacy in melanoma cells. The Ar-NLCs were fabricated using the high-speed homogenization-ultrasonication method, incorporating Gelucire 48/16, Castor oil, Capryol 90, and Tween 80. To analyze the impact of factors on Ar-NLCs, the Box-Behnken design (BBD) was utilized. The Ar-NLCs were characterized by particle size, polydispersity index, morphology, zeta potential, release kinetics, permeation, flux and stability. Additionally, Ar-NLCs cytotoxicity was assessed using the A375 cells. The Ar-NLCs demonstrated a particle size of 228.7 ± 44.5 nm, a zeta potential of -14.2 ± 2.64 mV respectively. The entrapment efficiency was 67.62 ± 4.46%. The α- arbutin release from NLCs followed Weibull kinetics. Notably, Ar-NLCs demonstrated a 2.53-fold higher permeability compared to Ar-SOL. Furthermore, Ar-NLCs exhibited significantly stronger cytotoxic effects against melanoma cells than Ar-SOL. This study reports the successful development of Ar-NLCs using a QbD approach. Enhanced transdermal permeability, enhanced cytotoxicity on melanoma cells, and sustained release of α-arbutin from NLCs were achieved. These findings indicate that NLCs offer a viable alternative drug delivery system for transdermal applications.
