The use of nanopolymers in anti-aging and regenerative skincare has emerged as a transformative advancement in dermatological science. Specific nanopolymeric systems such as chitosan nanoparticles, hyaluronic acid nanogels, poly(lactic-co-glycolic acid) (PLGA) nanospheres, dendrimers, and polymeric micelles have demonstrated significant potential in enhancing topical delivery and skin regeneration. These nanoscale polymers (1–100 nm) offer tunable physicochemical properties that enable efficient encapsulation, targeted delivery, and controlled release of active ingredients, including retinoids, peptides, antioxidants, and growth factors. Their small size and surface modifiability improve penetration across the stratum corneum and facilitate interaction with dermal fibroblasts, promoting collagen synthesis, enhanced hydration, and cellular renewal. In anti-aging applications, nanopolymers reduce wrinkles, fine lines, and hyperpigmentation by improving bioavailability and stability of sensitive compounds such as vitamins and retinoids. In regenerative dermatology, nanopolymeric scaffolds and nanocarriers support wound healing, angiogenesis, and extracellular matrix remodeling. Despite their promising benefits, concerns regarding long-term safety, regulatory frameworks, and production scalability remain. Continued research into biodegradable and biocompatible nanopolymers is expected to further advance personalized and precision skincare strategies. This review highlights the mechanistic roles and therapeutic potential of nanopolymers in reshaping modern anti-aging and regenerative skincare.
