Nanodermatology: A Blessing or Bane?

Nanoscience represents the study of particles on an atomic or molecular scale, whose size is measured in nanometers. A nanometer is equal to one billionth of a meter (i.e., 10-9 m). Nanotechnology, employing the concept of nanoscience, is an emerging branch of engineering pertaining to the use of particles on a nanoscale (1-100 nm). Applying this novel concept of nanotechnology in the field of dermatology for diagnostic, therapeutic and preventive applications is the Nanodermatology [1]. Nanotechnology has revolutionized the treatment of several skin diseases by its armamentarium of nano particles each with different physico-chemical properties. At the present scenario, an increasing demand is felt by scientists and pharmaceutical companies throughout the world for nanodermatology. One of attributing factors can be the huge number of registered patients with regard to dermatology, particularly cosmetology [2].
