Gel nail polish requires a curing process rather than simple air drying. This process involves exposure to ultraviolet (UV) or light-emitting diode (LED) light, which hardens the polish through a chemical reaction known as polymerization. This curing time is the primary factor determining when the manicure is fully set and resistant to smudging.
The utilization of UV/LED curing offers several advantages over traditional nail polish. It provides a significantly more durable and long-lasting finish, resisting chips and scratches for extended periods. The rapid curing time also reduces the likelihood of imperfections that can occur with slower-drying conventional polishes.
