Gel nails are a type of artificial nail enhancement made from a special gel that is cured under a UV light. They provide a glossy finish and are known for their durability, making them less prone to chipping compared to regular nail polish. The application process involves applying a base coat, followed by layers of colored gel, each cured under the UV light. After the final layer, a top coat is applied for added shine and protection. Gel nails can last for several weeks, making them a popular choice for those seeking long-lasting manicures.
