What is the primary purpose of using a top coat in gel layering?

The primary purpose of using a top coat in gel layering is to provide a protective shine. A top coat serves as a final layer that seals in the gel color beneath it, offering a glossy finish that enhances the overall appearance of the manicure. This layer not only adds visual appeal but also protects the underlying color from chipping, scratching, and fading, thereby prolonging the life and integrity of the manicure.

While adding color intensity, speeding up drying time, or enhancing the nail shape are considerations in nail technology, they do not represent the main function of a top coat. Color intensification is typically achieved through the gel color itself, and drying time is primarily a function of the curing process. Nail shape is influenced by the shaping and filing of the natural nail or enhancement, rather than by the top coat application. Therefore, the protective shine that the top coat provides is essential for both the aesthetics and longevity of the gel manicure.
