What is the purpose of a nail polish dryer?

The purpose of a nail polish dryer is to speed up solvent evaporation. When nail polish is applied, it consists of various solvents that need to evaporate for the polish to set and harden properly. A nail polish dryer uses heat or airflow to accelerate this evaporation process, thus allowing the polish to dry more quickly and reducing the risk of smudging. This is especially important in a nail care setting where efficiency and customer satisfaction are paramount.

Options that imply changing the color of nail polish or organizing nail polish bottles do not pertain to the function of a nail polish dryer. Additionally, maintaining the temperature of nail polish does not align with the primary purpose, as the focus of a nail polish dryer is on enhancing the drying process rather than managing temperature.
