Nanotechnology in Cosmetics: An Overview

Nanotechnology is transforming cosmetics by enabling safe, targeted delivery of active ingredients and improving skin penetration and drug action through advanced carrier systems like vesicular and particulate systems, emulsions, and nanocapsules. These technologies are applied in skin, hair, and nail care products, with significant use in sunscreens for UV protection. The review discusses the potential of nanotechnologies as next-generation carrier systems, advances in nano cosmeceuticals, and the regulatory landscape, as well as exposure routes of nanoparticles in the human body.
