Abstract :The word "nano" is derived from the Greek word "nanos" meaning "dwarf" and corresponds to a size of 1 x 10-9 meters. The technology dealing with these tiny substances is also called "nanotechnology". The famous American physicist Richard Feynman (1918–1988) proposed for the first time that there is a nano-sized world. Feynman addressed the mystery of nanoscales for the first time in his speech titled "There is more room below” at a conference in 1959. The scientist reported that many new discoveries would emerge if he could work in the atomic and molecular dimensions he imagined. In this speech, which is accepted as the beginning of nanotechnology, it was emphasized that nanoscale measurement and production methods should be developed first in order to be engaged in nano-scale studies. Nanotechnology is the creation of functional structures at nanometer scales by combining atoms and molecules. Nano is a scale, nanotechnology means technologies developed at that scale. Therefore, dealing with nanoscience and nanotechnology requires a multidisciplinary field. Its target is not a specific subject; it creates a wide coverage area that requires collaboration and includes many researches. With atoms and their arrangement; it means making innovations in materials, production techniques and developing new products with superior features suitable for needs. Nanotechnology is widely used in cosmetics, especially in moisturizers, sunscreen and anti-aging products: Apart from these, there are different uses such as make-up products, perfumery, oral and hair care products. The number of products containing nanoparticles is increasing day by day in the cosmetics industry.
