Can UV nail dryers dry polish without a UV top coat?
UV nail dryers are more commonly referred to as UV nail lights. The UV light being emitted by the UV lamps does nothing to dry nail polish, but the heat from the light unit itself will assist in drying nail polish. A more effective nail polish dryer would be a heat light with a small fan or some apparatus that has heating capabilities as well as a fan to circulate the air. A nail dryer that does not use UV light would be more economical than using a UV light unit to dry the nail polish.
