Cosmetics are preparations intended for external application to the human body for cleansing or beautifying effects without affecting the body’s structure or functions. Whereas, cosmeceuticals are cosmetic products having therapeutic effects for the treatment of different skin, face, hair, or nail conditions. Being the bridge between drugs and beauty care products, cosmeceuticals are the fastest-growing segment in the personal care industry with novel applications being frequently investigated.
Nanotechnology is the design, characterization, manufacturing, and application of materials and systems at the nanoscale level (1–100 nm). This technology is being extensively studied for drug delivery and is recently being investigated for application in cosmetic/cosmeceutical preparations. The incorporation of nanotechnology can offer greater advantages over traditionally used cosmetic products. The inclusion of nanoparticles in cosmetic preparations can improve their appearance, coverage, and adherence to the skin without altering the properties of these formulations. Moreover, the small size and large surface-to-volume ratio of nanoparticles enhance the therapeutic effect of cosmeceuticals by offering enhanced skin penetration and site specificity.
In this workshop, we will explore the different types of nanoparticles currently being used in cosmetic preparations. The different materials used, their applications, methods of preparation, and characterization will be discussed.
