Laser therapy is commonly associated with transient skin reactions such as erythema and edema, creating a need for effective post-procedural skincare strategies. In this study, we developed and characterized a novel bio-mask that integrates a hydrogel matrix with a lipid nanodispersion system designed to simultaneously deliver hydrophilic and hydrophobic active compounds. The key innovation of this formulation lies in the combination of a highly hydrophilic hydrogel structure with lipid nanoparticles embedded within a polymeric network, enabling enhanced bioavailability of active ingredients. Preliminary observations from instrumental measurements in a small group of healthy volunteers suggest that a single 60 min application resulted in notable improvements in skin hydration and elasticity, along with a reduction in transepidermal water loss (TEWL), erythema, and skin sensitivity. Furthermore, both the complete formulation and its individual components exhibited inhibitory activity against collagen and elastin glycation, while promoting type I procollagen synthesis. Importantly, this study provides new evidence for the synergistic interaction between hydrogel matrices and lipid nanodispersion systems in modulating skin barrier function and biochemical aging markers. The formulation, composed entirely of ingredients of natural origin, proved to be an effective carrier for active compounds and showed measurable benefits for skin hydration and barrier-related parameters.
