Nanotechnology has the potential to generate advancements and innovations in formulations and delivery systems. This fast-developing technology has been widely exploited for diagnostic and therapeutic purposes. Cosmetic manufacturers employ nano-sized ingredients to improve UV protection, skin penetration, color, the release of fragrance, finish quality, anti-aging effect, and a variety of other properties. Consumers all over the world are looking for more natural and less harmful products to use on their skin, as it is one of the most important features. Drawbacks of traditional cosmetics can be overcome by using nanocosmeceuticals. Nanocosmetics and nanocosmeceuticals have been extensively explored for skin, hair, nails, lips, and teeth, and the inclusion of nanomaterials has been found to improve product efficacy and consumer satisfaction. Nanocosmeceuticals are a combination of cosmetics and pharmaceuticals; they just don’t conceal and make the skin fine but also cure and heal it now. The use of nanomaterials (NMs) by the cosmetic industry aims for long-lasting effects and increased stability. The high surface area of nanomaterials allows for more efficient transport of the ingredients through the skin. Also, many other features of nanoparticles help improve the usage of cosmetics, like controlled drug release, enhanced bioavailability, moisturizing power, entrapment and penetration efficiency, enhanced stability, and improved results. In this chapter, the emerging role of nanotechnology in skincare will be discussed.
