Gels cure when photoinitiators absorb specific wavelengths. Traditional UV lamps emit broadly around 365 nm and cure most gels more slowly; LED lamps emit narrow bands around 395 to 405 nm and cure compatible gels in seconds; dual-wavelength lamps cover both. The gel maker's recommended lamp and cure time matter more than wattage. Some dermatologists suggest broad-spectrum sunscreen or UV-protective gloves for clients.
Under-cured gel lifts, peels and can irritate skin. The lamp must match the gel.

Skin precautions
Studies of UV nail lamps are ongoing. Offering broad-spectrum sunscreen or UV-protective fingerless gloves is a reasonable precaution.

Common questions
Can I use any gel with an LED lamp?
Only gels formulated for LED wavelengths. Check the gel maker's lamp compatibility.
Does higher wattage mean faster curing?
Not necessarily. Wavelength match, LED arrangement and distance matter more.
Are UV nail lamps safe?
Exposure per session is short, but research on long-term effects is ongoing. Sunscreen or UV gloves reduce skin exposure.
What is a dual-wavelength nail lamp?
A lamp with LEDs covering both UV and visible-violet ranges, so it cures more gel types.
