Nanocosmeceutical and Emerging Trends in Pharmacy

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. The application of nanotechnology in cosmetics has been shown to overcome the drawbacks associated with traditional cosmetics and also to add more useful features to a formulation. Nano cosmetics and nano cosmeceuticals 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. This is leading to the replacement of many traditional cosmeceuticals with nanocosmeceuticals. Novel nanocarriers like liposomes, niosomes, nanoemulsions, microemulsion, solid lipid nanoparticles, nanostructured lipid carrier, and nanospheres have replaced the usage of conventional delivery system. These systems enhance the bioavailability, stability, and efficacy of active ingredients, offering controlled release and targeted delivery features that are crucial for optimizing cosmetic results. Nanotechnology facilitates improved penetration of actives into the skin, protects ingredients from degradation, and ensures sustained release, thereby enhancing the therapeutic effectiveness of cosmeceuticals. This review highlights the various novel carriers used for the delivery of cosmeceuticals, their positive and negative aspects, marketed formulations, and their toxicity.
