The commonly used lamps in nail art are ultraviolet (UV) lamps and LED lamps. These two lamps are mainly used to cure gel nail polish or resin used in the enhancement process.

1. Ultraviolet (UV) lamp: This lamp can cure gel nail polish by emitting ultraviolet light of specific wavelength. UV lamps are usually divided into two types: low pressure and high pressure. Low pressure UV lamps are more common because they cause less damage to the skin. However, prolonged exposure to UV light may cause harm to the skin and eyes, so caution should be taken when using it.

2. LED lamp: LED lamp is a more and more popular substitute in recent years. It can cure gel nail polish by emitting high-energy visible light. Compared to UV lamps, LED lamps are more energy-efficient, have a longer lifespan, and cause less damage to the skin and eyes. However, not all gel nail polish can be completely cured under LED light, so it is very important to choose compatible light and nail polish.

Reasonable use of these lights during nail art can improve the durability and aesthetics of the nail art effect. At the same time, in order to protect the health of customers, nail technicians should ensure the correct use of lamps and take necessary safety measures.
