This study reports the development of a dermato-cosmetic hydrogel combining retinol (2% wt) and bioactive glass (1.25% wt) in a Carbopol-based matrix enriched with hyaluronic acid. The formulation was synthesized using high-shear dispersion and evaluated through TGA, DSC, FTIR, and XRD. Thermal analysis indicated strong water-polymer interactions, while FTIR and XRD confirmed amorphous structure favorable for controlled release. The hydrogel showed high conductivity (25000 µS/cm) and alkaline pH (12.4), attributed to its 85% water and triethanolamine content. Turbiscan and microscopy confirmed physical stability. Microbiological tests confirmed sterility. In vivo VISIA analysis on five volunteers over 45 days revealed visible improvements in wrinkles, pores, red areas, UV spots, and porphyrins, with notable changes as early as day 14. These results support the hydrogel’s potential for effective and well-tolerated dermal delivery of retinol.
