Nanotechnology is a cutting-edge field of science that covers the design, characterization, production, and application of materials, devices, and systems by manipulating shape and size at the nanoscale scale. The newest and most pioneering technology currently available is the inclusion of nanotechnology in cosmetic composition.
Nanoscale-sized chemicals are used in cosmetic formulations to deliver benefits such as enhanced UV protection, deeper skin penetration, long-lasting effects, greater colour, higher finish quality, and many more.

One of the newest technologies used in cosmetic products is called micellar nanoparticles. It is quickly gaining popularity and is being widely distributed in both domestic and foreign markets. The capacity of a nano emulsion technology to create tiny, highly surface-area micellar nanoparticles allows for efficient delivery of bioactive ingredients to the skin. By combining bioactive ingredients in cosmetic formulation with innovative nanocarriers such liposomes, niosomes, solid lipid nanoparticles, nanocapsules, micelles dendrimers, and metal nanoparticles, some cosmetics' quality and effectiveness have been improved.

Additionally, it shows how the application of nanotechnology to a variety of cosmetic markets has enormous promise. It is suggested that the effective nano emulsion delivery technique used in cosmetics be used to other industries, such as food and pharmaceuticals.
