Why is it important to use a base coat before applying nail polish?

Using a base coat before applying nail polish is crucial for several reasons, and one of the key benefits is to enhance adherence and prevent staining. The base coat creates a barrier between the natural nail and the colored polish. This not only helps the polish adhere better, ensuring a more even and long-lasting application, but also protects the nails from potential staining caused by darker pigments in colored nail polishes. Without this protective layer, the natural nail can absorb these pigments, leading to discoloration.

While there are other benefits of using a base coat, such as potentially prolonging the wear of the polish and providing a smoother surface for application, the primary focus of enhancing adherence and preventing staining is fundamental to maintaining the health and appearance of the nails.
