What is the primary purpose of nail polish?

The primary purpose of nail polish is to add color and shine to the nails. This cosmetic product enhances the appearance of the nails, providing a vibrant color palette and a glossy finish that can improve the overall aesthetic of hands and feet. Nail polish serves not only as a beauty enhancement but also allows individuals to express their personal style and creativity through various colors and designs. The visual impact of colored nails has made nail polish a popular choice in beauty routines, often used for special occasions, daily wear, or as part of a complete manicure.

While there are other products and practices in the nail care regimen that serve functions such as protecting the nails or providing moisture, the core function of nail polish is specifically aimed at aesthetic enhancement through color and shine.
