As nail care evolves, so do the techniques used to enhance and decorate these small but significant parts of our bodies. The rise of nail art has transformed simple manicures into intricate designs and artistic expressions. Techniques like gel manicures, acrylics, and nail stamping have gained immense popularity. Gel polish, for instance, offers a long-lasting finish that resists chipping and provides a glossy look. Meanwhile, acrylics allow for creativity with lengths and shapes that are often unattainable with natural nails.
