1. Nanotechnology is being used to enhance the quality of cosmetic products, including face masks and other personal care items. 2. Nanofiber cosmetic masks are made by mixing polymer solutions with active ingredients, resulting in a mask that adheres well to the skin and delivers active substances effectively. 3. The use of nanomaterials in masks provides benefits such as easy delivery of active substances, high retention, breathability, and deep skin layer delivery.
