Nanotechnology in cosmetics refers to the use of nanomaterials—substances that have been engineered at the nanometer scale (typically between 1 to 100 nanometers)—to enhance the formulation, effectiveness, and delivery of cosmetic products. This technology can improve the performance of cosmetic formulations in various ways. Here are some key aspects of nanotechnology in cosmetics: 1. **Improved Delivery Systems**: Nanoparticles can serve as carriers for active ingredients, allowing for better penetration into the skin.
