Nail polish is a cosmetic product applied to the nails to enhance their appearance. It comes in various colors and finishes, such as glossy, matte, or glittery. The main ingredients typically include a film-forming agent, solvents, and pigments, which help create a smooth and colorful coating. To apply nail polish, one usually starts with a base coat to protect the nails, followed by one or more layers of colored polish, and finishes with a top coat for shine and durability. Nail polish can be easily removed with nail polish remover, which contains solvents that dissolve the polish.
