1. Introduction to Nail Gel
Nail gel, also known as UV nail gel or phototherapy nail gel, is an upgraded product of nail polish that combines the characteristics of phototherapy (UV) products. In the past two years, it has rapidly gained popularity in the global nail art market.

The birth of nail gel originated from a beautiful wish. When customers visit nail salons for nail polish application, the most concerning issues are drying speed and longevity. These are the exact issues that traditional nail polish, existing for over a hundred years, has struggled to address. With the increasing demand for solutions to these issues, nail gel emerged. This new nail art method features low odor, eco-friendliness, health benefits, and offers a high gloss and a wide range of colors that traditional nail polish cannot match. It boasts better durability, ease of application, convenience in nail art design, among other advantages compared to traditional nail polish.

Nail gel is generally divided into base gel, color gel, and topcoat gel. Compared to traditional nail polish, it is solvent-free, low in irritation, low in odor, cures quickly, has a bright and transparent finish, and has a longer longevity before chipping. Its application is simple and convenient, making it highly favored by nail art enthusiasts.

2. Light Sources for Nail Gel
Nail gel is typically cured using traditional UV lamps or LED lamps. LED lamps do not emit heat, do not harm the skin, cure faster, but come at a higher price. Traditional UV lamps, on the other hand, emit spectra that are mostly unused (such as visible light and infrared radiation), resulting in slight heating and skin irritation during curing. They also have lower efficiency, leading to longer curing times compared to LED lamps, but are cost-effective. Common UV lamps usually have a power of 36 watts, while LED lamps typically have a power of 12 watts. Comparison of power and curing times between common UV lamps and LED UV lamps:

Common UV Lamp LED UV Lamp
Power 9 watts 18 watts 36 watts 4 watts 9 watts 12 watts
Base Gel 180 seconds 150 seconds 120 seconds 40 seconds 30 seconds 30 seconds
Color Gel 180 seconds 150 seconds 120 seconds 40 seconds 30 seconds 30 seconds
