Nanotechnology is the study of atoms and molecules at the nanoscale, which is 80,000 times smaller than the width of a human hair. Nanoscale versions of chemicals are used by cosmetic producers to give better UV protection, deeper skin penetration, long-lasting effects, enhanced color and finish quality, and so on. Nanocosmeceuticals have a variety of advantages. They do this by modulating the release of active compounds from carriers based on a variety of criteria such as physical or chemical interactions between the components, drug content, polymer and additives, ratio, and production process. They're found in hair care products like shampoos and conditioners, and they're used to treat hair loss and prevent greying. Scientists have developed new technologies and delivery techniques that are currently being employed in the production of cosmeceuticals. The use of cosmeceuticals is expanding, and conventional procurement mechanisms are being replaced with innovative delivery technologies.
