The article "Nanocosmetics and Skin Health: A Comprehensive Review of Nanomaterials in Cosmetic Formulations" explores the impact of nanotechnology on skincare, focusing on the effects of nanocosmetics on skin health. Nanocosmetics, which use materials at the nanoscale (1-100 nanometers), enhance the effectiveness and delivery of active chemicals through advanced delivery methods such as nanoemulsions and nanocapsules. These methods improve stability and targeted distribution, allowing active ingredients to penetrate deeper into the skin. The review includes in vitro, animal, and clinical studies, excluding those unrelated to skin health or nanocosmetics. Key benefits of nanocosmetics include improved penetration, enhanced bioavailability, and tailored solutions for various skin issues. However, concerns over the safety of nanoparticles, including potential systemic absorption and penetration, are still under investigation. The article also discusses the use of nanomaterials in sunscreen, nutricosmetics, nanoemulsions, nanoencapsulation, fullerenes, nanodiamonds, and nanopeptides, highlighting their potential in addressing specific skin concerns. Overall, nanocosmetics offer a more efficient and focused approach to skincare due to their advanced delivery mechanisms and improved stability.The article "Nanocosmetics and Skin Health: A Comprehensive Review of Nanomaterials in Cosmetic Formulations" explores the impact of nanotechnology on skincare, focusing on the effects of nanocosmetics on skin health.
