Gel nails are a type of artificial nail enhancement made from a special gel that is cured under a UV light or LED light. This process hardens the gel, creating a durable and glossy finish that can last for weeks without chipping. Gel nails can be applied over natural nails or used to extend the length of the nails. The application of gel nails typically involves several steps, including nail preparation, applying a base coat, and layering the gel. After curing each layer, a top coat is added for shine and protection. Gel nails are popular for their long-lasting results and versatility in design.
