No, not all nail polish dries in UV light. UV light is typically used to cure or dry gel nail polish, which contains photo-initiators that are activated by UV light. Regular nail polish, also known as traditional or regular enamel, does not contain these photo-initiators and therefore does not require UV light to dry.
Regular nail polish typically dries through a process of evaporation and can take anywhere from a few minutes to a few hours to completely dry depending on the brand and the thickness of the layers applied. However, some regular nail polish brands do offer fast-drying formulas that can dry in a matter of minutes, without the need for UV light.
It’s important to note that UV light can be harmful to the skin, so it’s important to use caution and protect your skin when using UV light to cure gel nail polish. If you have any concerns about using UV light to dry your nails, consider using regular nail polish or trying out fast-drying formulas instead.
