The central challenge with traditional gel nail polish lies in its formulation, which requires a specific wavelength of ultraviolet (UV) light to initiate polymerization. This process hardens the gel, creating a durable and long-lasting finish. Without this curing step, the gel remains tacky and prone to smudging. Alternatives are explored to achieve a similar hardened state without UV exposure.
UV light exposure, even in nail lamps, carries potential risks associated with skin damage. The desire to mitigate these risks fuels the demand for methods that circumvent the need for specialized equipment. Furthermore, accessibility to UV lamps can be a barrier for some users, making alternative hardening techniques more appealing and practical.
