Nail products generally fall into these two categories, but many girls may not be able to tell the difference.
Nail polish is more popular and it does not need to light, by natural air drying. Some fairies think nail polish is hard to dry. UV or LED lights can speed up the drying, but actually they can't. Nail polish lights only work for glue, not nail polish.
Nail polish needs special UV/LED lamp to solidify. After solidification, it can last longer than nail. It can basically last for 20-30 days.
Nail polish remover needs to use special nail polish remover products and ordinary nail polish remover cannot be removed. It is recommended to use nail remover bag. If it is not removed properly (such as forcibly removing it), it will cause more damage to the nails.
