What is the primary use of a metal pusher?

The primary use of a metal pusher is to loosen the cuticle. This tool is designed to gently push back the cuticle, which helps to remove any dead skin cells and debris that accumulate at the base of the nail. By doing so, it allows for clearer visibility of the nail plate and creates a clean area for nail services. Properly loosening the cuticle is essential for maintaining nail health and preparing the nail for further treatments such as manicures or polish application.

The other options focus on different aspects of nail care: cleaning under nails is typically done with a different tool, shaping nails is achieved using specialized files or buffers, and applying polish requires brushes specifically designed for that purpose. Each of these actions has its own tools and techniques, highlighting the distinct function of the metal pusher in cuticle care.
