Emerging Trends of Nanotechnology-Based Advanced Cosmeceuticals

Cosmeceuticals are the fastest growing sector of the personal care industry, and the use of several topical cosmeceutical treatments has increased significantly over the years. Nanotechnology has an impact on the cosmetics industry. Novel nanocarriers, such as liposomes, niosomes, nanoemulsions, gold and silver nanoparticles (NPs), solid lipid NPs, and nanospheres, have superseded the use of conventional delivery systems. In nano-cosmetics and nano-cosmeceuticals for skin, hair, nails, lips, and teeth, nanomaterials (NMs) have improved product performance and customer satisfaction. Nanotechnology-based cosmeceuticals offer the advantages of product diversity, improved bioavailability of active ingredients, and higher visual attractiveness of cosmeceutical products with long-lasting effects. However, the increasing use of nanotechnology in cosmeceuticals has raised concerns about potential health risks and ability of NPs to pass through the skin. This review discusses the various types of NPs used in various classes of cosmeceuticals, the availability of nanotechnology-based cosmeceuticals, the potential dangers associated with exposure to NPs, and the most recent developments in their regulation. The purpose of this review article is to provide consumers and regulators with an overview of nano-cosmetics and nano-cosmeceuticals and their applications in the cosmetic industry, as well as information on toxic effects associated with continued and sustained use of these products, which may help them gain a better understanding of benefits and encourage prudent use.
