What can I use if I don’t have UV light
If you don't have a UV light to cure your gel nails, you can try using a fan to completely dry them. Make sure the fan is several inches away from your nails so that they do not blow off before they are fully cured. The speed at which the airflow hits the nail will determine how long it takes for them to dry and set.
Is A UV light bad for you
Exposure to UV radiation can cause damage to your skin, especially if you're exposed over time. For example, it can lead to premature wrinkles, age spots, and even skin cancer. But the FDA views nail curing lamps as low risk when used as directed by the label.
Can you feel UV radiation on your skin
You can feel the sun's heat. But you can't see or feel the sun's UV radiation. UV can reach you directly from the sun. It can also be reflected off different surfaces and scattered by particles in the air.
