: Herbal cosmeceuticals are a rapidly expanding sector of the personal care industry, and their use has greatly expanded over time. The advancement of research and development is demonstrated by nanotechnology, which boosts product efficacy by delivering innovative solutions. The application of nanotechnology is growing in the field of cosmeceuticals to address numerous shortcomings of conventional herbal products. Lower penetration and high compound instability of various cosmetic products for prolonged and enhanced compound delivery to beauty-based skin therapy are the main problems with the use of phyto-based cosmeceuticals. Nanosized delivery technologies are currently being used in cosmeceutical industries and products for prolonged and improved delivery of phyto-derived bioactive chemicals to solve these drawbacks. The aseptic sensation of many cosmeceutical products is improved by nanosizing phytocompounds, which also improve skin-protective properties and sustained delivery. Nanocosmeceuticals are now commonly utilized on skin, hair, lips, and nails to treat disorders including wrinkles, photoaging, hyperpigmentations, dandruff, hair damage, chapped lips, etc. Some of the cutting-edge nanotechnologies now being used for improved delivery of the phytoconstituents in skin care therapy include liposomes, ethosomes, glycerosomes, transferosomes, niosomes, phytosomes, nanostructured lipid carriers, solid lipid nanoparticles, polymeric nanoparticles, nanoemulsions, nanogels, etc. The advantages of these novel nanocarriers include improved skin penetration, controlled and prolonged drug release, increased stability, site-specific targeting, high entrapment efficiency, and improved bioavailability. Several phytoconstituents such as curcumin, aloe vera, resveratrol, lycopene, tocopherol, quercetin, catechins, and lutein have been successfully nanosized by employing various delivery technologies and incorporated in various gels, lotions, and creams for skin, lip, hair, and nail care for their sustained effects. The present article primarily focuses on the use of phytocompounds in various cosmeceutical products, diverse classes of innovative nanocarriers employed for delivering herbal nanocosmeceuticals, and the use of various phytobioactive compounds in novel nanocosmeceutical formulations to improve skin-based therapy.
