Nanotechnology is an innovative area of science that includes the design, characterization, production, and application of materials, devices, and systems by controlling shape and size at the nanometer scale (1–100 nm). Nanotechnology incorporation in the cosmetic formulation is considered as the hottest and emerging technology available. Cosmetic manufacturers use nanoscale size ingredients to provide better UV protection, deeper skin penetration, long-lasting effects, increased color, finish quality, and many more. Micellar nanoparticles are one of the latest fields applied in cosmetic products that becoming trending and widely commercialized in local and international markets. The ability of the nanoemulsion system to form small micellar nanoparticles size with high surface area allowing to the effectiveness of bioactive component transport onto the skin. Oil in water nanoemulsion is playing a major role as an effective formulation in cosmetics such as make-up remover, facial cleanser, anti-aging lotion, sun-screens, and other water-based cosmetic formulations.
