What type of light is used to cure no-chip polish?

• A. Light-Emitting Diode
• B. Ultraviolet Light
• C. Infrared Light
• D. X-Ray Light

Answer: (A)

Gels and no-chip polishes cure through a light-activated polymerization process. The product contains photoinitiators that respond to specific light wavelengths, triggering the gel to harden. Light-emitting diode sources are designed to emit a spectrum that most modern no-chip gels are formulated to respond to, so they cure quickly and efficiently—often in under a minute per coat—while keeping heat low. This combination of fast, safe curing is why LED light is the preferred option for curing no-chip polish. Ultraviolet light can also cure gels, but it generally requires longer exposure and can produce more heat, making LED the more convenient and common choice today. Infrared light isn’t used to initiate the chemical cure of nail gels, and X-ray light isn’t a curing method for nail products. The key idea is that curing depends on activating the gel’s photoinitiators with a compatible light, and LED provides that compatibility for many no-chip formulas.
