The aging of skin is a multifaceted biological phenomenon influenced by both intrinsic and extrinsic factors. As awareness among the public increases, there is a growing interest in natural ingredients and cutting-edge cosmetic solutions that enhance skin appearance and mitigate the aging process. Nanotechnology has emerged as a significant field within cosmeceuticals, providing innovative solutions that overcome the limitations of conventional cosmetic formulations by enhancing delivery, stability, and targeted efficacy. This review synthesized contemporary research on nanotechnology-driven approaches utilized in anti-aging skincare. A comprehensive search of scientific databases, including Pub- Med, Scopus, and Google Scholar, was performed to identify research articles and review papers using keywords, such as "nanotechnology," "skin aging," "anti-aging cosmetics," "nanocarriers," and "bioactive compounds." The emphasis was placed on studies that highlight nanosized delivery systems and their mechanisms in addressing issues related to skin aging. Bioactive compounds targeting anti-aging, such as antioxidants (including ascorbic acid, alpha-tocopherol, lipoic acid, and coenzyme Q10) and plant extracts (such as green tea, turmeric, and resveratrol), were successfully integrated into nanocarrier systems. These systems, comprising lipid nanoparticles, polymeric carriers, nanoemulsions, dendrimers, and fullerenes, demonstrate improved penetration, stability, and controlled release compared to traditional formulations, thereby enhancing the effectiveness of active ingredients in addressing signs of aging. Nanotechnology-driven skincare has demonstrated enhanced delivery, stability, and bioavailability of anti-aging compounds, addressing limitations of conventional formulations. Nanosized carriers improve penetration and controlled release, optimizing the functional benefits of antioxidants and botanical extracts. However, concerns related to safety, toxicity, and regulatory compliance require further investigation. Sustainable nanocarrier development and interdisciplinary collaborations will be essential for balancing efficacy with safety. Continued research will be crucial to establishing standardized guidelines and ensuring the successful commercialization of nano-based anti-aging cosmetics. Nanotechnology presents significant potential for the development of effective antiaging cosmetic products. The use of nanosized delivery systems significantly enhances the efficacy of active ingredients, providing a viable alternative to traditional formulations. Nonetheless, challenges related to safety, toxicity, regulatory compliance, and long-term clinical application must be addressed in future research to facilitate the successful commercialization of these products. Additionally, future investigations should consider sustainable practices.
