Background: Nanoscience is the section of science related to the study of
minute particles on an atomic or molecular scale, whose size is measured in nanometres.
Nanotechnology serves as one of the most capable technologies and accomplished approaches
of the 21st century which is safe and efficacious for novel drug delivery systems.
Now, nanotechnology is used widely in the field of cosmetics and dermatology
due to the improved properties of the atoms at the nano level.
Objectives: This mini-review article has been planned to discuss basic facts regarding
nanotechnology as well as various nanotechnology drug delivery systems used in cosmetics
and dermatology, applications of nanotechnology and overview of patents
published recently in the field of nanocosmetics. The current status of regulatory as well
as safety and quality aspects for the use of nanotechnology in cosmetics and
dermatology will also be discussed.
Discussion: Cosmetics industry is the sixth largest industry among United States patent
holders in nanotechnology. Nanotechnology has transfigured the treatment of several
skin diseases. Possible applications of nanotechnology in dermatology and cosmetology
include sunscreens, moisturizers, anti-aging formulations, anti-sepsis, nails and hair
care. The recent studies to date suggest that the nano-cosmeceuticals have no safety issues
with skin as well as human health, although the nano-cosmeceuticals are beneficial
for human health in a number of ways such as guarding against UV rays which may
cause skin cancer. The regulatory bodies had performed an active debate on the potential
risk of nano-cosmeceuticals on human health and steps have been taken for thecoordination
of regulatory rules.
