Nanotechnology: Current Developments, Applications and Patents for Non-invasive Topical Cosmetics and Dermatological Therapeutic Delivery

Nanotechnology exhibits the advancement in the field of invention, by improving the potency of the formulation through the delivery of inventive solutions. To resolve several limitations related to conventional formulations, nanotechnology applications are increasing in the cosmetics and dermatological area. Cosmetic and dermatological preparations are considered a thriving branch of the body care arena and their usage has increased dramatically through the past years. Scientists are designing innovative delivery mechanisms and emerging innovations that are presently being utilized in the development of cosmetics. Inventive nanocarriers such as niosomes, liposomes, microemulsions, nanoemulsions, solid-lipid nanoparticles, nanospheres, and nanostructured (lipid) carriers have substituted the use of traditional drug delivery. These innovative nanocarriers have the convenience of better skin permeation, sustained and controlled drug delivery, precise location, higher stability, and greater incorporated capability. Since the usage of cosmetics has increased, the usual delivery system has been substituted by modern delivery approaches. The introduction of newer advancements and novel drug delivery systems make cosmetics and cosmeceuticals more popular with increased market share. This review article on nanotechnology employed in cosmetics and dermatology emphasizes the numerous innovative nanocarriers designed for cosmetic and dermatologic drug delivery, their negative and positive aspects, and their toxicity.
