What device is commonly used to dry nail polish quickly?

The commonly used device to quickly dry nail polish is a nail dryer. Nail dryers are specifically designed to speed up the drying process of nail polish by using airflow or heat. Many models utilize a combination of both techniques to effectively evaporate the solvents in nail polish at an accelerated rate, which helps to create a smooth, dry finish without smudges.

In contrast, while a nail fan may provide air circulation, it is generally less effective than a dedicated nail dryer in terms of drying speed and efficiency. UV light is used primarily for curing gel nail polish rather than standard polish, as it activates the special formulas in gel products. Additionally, a heating pad is not intended for this purpose and can potentially damage the polish or cause uneven drying. Thus, the nail dryer is the most appropriate tool among the options for hastening the drying time of traditional nail polish.
