Which tool is designed to shorten the drying time of nail polish?

Nail dryers are specifically designed to shorten the drying time of nail polish by providing a controlled airflow and/or heat to help the polish set more quickly. This is important in nail care because it enhances the efficiency of the manicure process, allowing clients to leave with their nails dried and polished without the risk of smudging. Nail dryers typically work by blowing air across the wet polish or gently warming the nails to accelerate the curing process.

Other tools mentioned in the question serve different functions. Ultraviolet lamps, while they do help with curing certain types of gel polishes, are not used for traditional nail polish and therefore are not appropriate for shortening drying time in that context. A metal pusher is used for pushing back cuticles and shaping the nail but has no bearing on drying nail polish. A disinfection container is utilized for sanitizing tools and implements but does not impact the polish itself. Thus, the primary purpose of nail dryers directly aligns with the goal of reducing drying time for nail polish, making it the correct choice.
