Nanotechnology is a novel expanding area of research involved in manipulating properties and structures at nanoscale. Nanoparticles have recently received considerable attention in medical, biomedical, and biotechnological applications and have emerged in the fields of cosmetics and dermal preparations. This chapter introduces the cutting-edge science related to nanoparticles' role in the cosmeceutical industry. It starts by presenting skin structure and function. It then explains mechanisms of nanoparticle permeation through skin including transcellular, intercellular, and transappendageal pathways. Various ingredients used in beauty care products and their novel nanoformulations are discussed. A full discussion of the main nanoparticles that have been used in cosmetics is presented. The toxicity of nanoparticles, safety requisites for these products, and the regulation of nanoparticle applications in beauty care products are then described. |
