Abstract

 Periorbital skin is particularly susceptible to premature aging due to its thin structure, reduced barrier function, and increased vulnerability to oxidative stress. Caffeine, a naturally occurring methylxanthine, has demonstrated potential for improving microcirculation, reducing puffiness, enhancing lipolysis, and providing antioxidant and anti-aging benefits. However, its incorporation into topical formulations may be limited by its hydrophilicity and relatively rapid diffusion from conventional delivery systems. The present study aimed to develop and characterize a caffeine-loaded nanostructured lipid carrier (NLC) gel for targeted periorbital skin care with potential anti-aging and anticellulite activity. Caffeine-loaded NLCs were prepared using a combination of solid and liquid lipids and optimized for particle size, polydispersity index, zeta potential, entrapment efficiency, and drug loading. The optimized NLC dispersion was incorporated into a suitable gel base and evaluated for pH, viscosity, spreadability, homogeneity, drug content, in vitro drug release, skin permeation, and stability. The formulation was further assessed for its potential antioxidant and anti-aging/anticellulite effects using appropriate in vitro models. The developed NLC gel is expected to provide sustained release and enhanced topical delivery of caffeine, thereby improving its residence time and therapeutic efficacy at the skin surface. The proposed formulation may offer a promising nanotechnology-based approach for managing periorbital puffiness, early signs of skin aging, and localized cellulite-related cosmetic concerns. Further in vivo and clinical studies are warranted to establish its long-term safety, efficacy, and consumer acceptability.
