The curing process for gel nail coatings involves exposure to ultraviolet (UV) or light-emitting diode (LED) lamps. This exposure polymerizes the gel, hardening it from a liquid to a solid state. Unlike traditional nail lacquers that dry via evaporation, gel polish relies on this photochemical reaction. For example, a typical application requires 30-60 seconds of exposure under an LED lamp or 2 minutes under a UV lamp for each layer.
Proper curing is crucial for achieving a durable, long-lasting manicure. Insufficient exposure can lead to chipping, peeling, or a tacky finish. The benefits of adequately cured gel nail coatings include extended wear, resistance to damage, and a high-gloss appearance. Historically, advancements in gel polish formulations and curing lamp technology have significantly reduced the time required for this process, improving efficiency and convenience for both technicians and clients.
